Section 1 - Product Overview
Introduction
D-Link’s DWM-311 4G LTE M2M Modem is a robust 4G LTE modem that provides blazing fast connection speeds for
embedded Machine-to-Machine (M2M) applications. The single mode LTE modem provides an economical and reliable
high-speed connection suitable for the most demanding Internet of Things (IoT) applications. This cost-eective device is
pre-congured to provide a complete connectivity solution out of the box.
The industrial-grade casing means the DWM-311 provides reliable high-speed connectivity in extreme conditions. The
corrosion-resistant zinc-plated steel case and wide operating temperature and humidity tolerance mean that the DWM-311
is ready for the most demanding M2M applications in virtually any environment. Wall mounts and exible interfaces allow
the DWM-311 to be mounted virtually anywhere for optimal connectivity.
The DWM-311’s USB and Ethernet interfaces allow connectivity to be added to virtually any device. Ethernet means
driverless, instant access for any Ethernet-enabled device, without the need for pre-conguration or special software.
Standard USB protocols allow you to add high-speed Internet access to devices not traditionally equipped with network
adapters. Ethernet makes the DWM-311 a true plug-and-play solution, suitable for mass deployment or small scale use.
Should unique settings be required, the easy-to-use web interface can be congured through any web browser.

Section 2 - Installation
Before You Begin
Installation
This section will guide you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area
such as a closet, cabinet, or in an attic or garage.
Observe the following precautions to help prevent shutdowns, equipment failures, and personal injury:
• Install the DWM-311 in a cool and dry place. Refer to the technical specications in the user manual for the acceptable operating temperature
and humidity ranges.
• Install the modem in a site free from strong electromagnetic sources, vibration, dust, excessive moisture, and direct sunlight.
• Place antennas in an unobstructed area with clear LTE signal. Avoid metal boxes, brick walls, and other dense materials. Use the web interface
to conrm signal strength before permanent installation.
• Visually inspect the power connector and make sure that it is fully secure.
• Do not stack any devices on top of the modem.
Attach the External Antennas
The DWM-311 requires two external antennas to function correctly. The included antennas are interchangeable, but third party antennas may
require connection to specic ports.
1. Attach the antennas to the included magnetic mounts. Turn the hex nut clockwise to fasten the antenna.
2. Place antennas where they will receive optimal signal. Arrange them so they point upward.

Section 2 - Installation
Powering the Modem
The modem can be powered either directly via mini-USB or via Power over Ethernet (PoE) using a PoE splitter.
Using included Mini-USB cable
Use the included mini-USB AC adaptor to power the modem. Attach the USB connector to the included AC adaptor. Attach the AC adaptor to a wall
socket. Insert the mini-USB connector into the port on the modem labelled with the symbol. The power LED will turn green to indicate the modem
is receiving power.
Using Power over Ethernet (PoE)
The DWM-311 can be powered via Power over Ethernet (PoE) (sold separately) by connecting a 5.5 mm DC to mini-USB adaptor (sold separately)
to a PoE splitter. This may be useful when long cable lengths required. Standard PoE has a range of up to 330 ft (100 m). The following steps outline
setting up the modem with a PoE Splitter/Injector kit.
1. Verify your PoE splitter is set to output 5 volts.
Warning: Higher voltages may damage the DWM-311.
2. Attach the PoE splitter’s DC-OUT to the DWM-311’s mini-USB power input using the DC-to-Mini-USB adaptor (sold separately). The power input
is labelled with the symbol.
3. Once the antennas are placed, attach both antenna cables to the DWM-311’s external SMA connectors, labelled DIV and PRI. Turn the hexnut
clockwise to secure the cables.
Note: The included antennas are interchangeable. Third party antennas may require connection to specic ports.
Page 11
8D-Link DWM-311 User Manual
Section 2 - Installation
3. Attach the PoE splitter’s LAN OUT to the DWM-311’s DATA1 port on the DWM-311.
4. Finally, connect the PoE injector’s LAN-IN port to an available Ethernet port on
your end device and plug in the injector’s power cord into a power outlet as
shown in the diagram.
Note: the above case assumes you are using a D-Link DPE-301GI 1-Port Gigabit PoE
Injector and D-Link DPS-301GS 1-Port Gigabit 30W PoE Splitter (sold separately).
Other PoE congurations may vary.
Connecting Devices
After the DWM-311 has been successfully installed, the modem can be connected
to the end device via either of the following connection methods:
Over Ethernet
The Ethernet port can be connected to an end device. Use a standard Category 5/5e/6
RJ-45 Ethernet cable to connect the end device to the modem. The port will autonegotiate to the highest possible port speed based on the connected device. Note
that the DWM-311 supports a maximum transfer speed over Ethernet of 100 Mbps.
Over USB 2.0
To connect the modem over USB, connect a micro-USB cable (not included) to the
port marked DATA2 on the back panel. Insert the other end of the cable into a free
USB port of the device you wish to connect.
Note: The modem cannot accept power over micro-USB, only over mini-USB through
the port labelled with the symbol.
Connect DATA1 on the
DWM-311 to the Ethernet
port labelled PoE OUT on the
PoE injector. Connect the
Mini-USB port to the
splitter’s DC OUT using an

Router Mode
By default, the DWM-311 operates in bridge mode. Any attached devices are assigned
an IP address directly by the ISP. However, for compatibility purposes, some devices
may require an IP address assigned from a local DHCP server. Enabling router mode
ensures that all IPs on the subnet will be assigned by the DWM-311’s internal DHCP
server, and all trac relayed to the ISP via NAT (Network Address Translation).
Note: NAT is considered a type of rewall*, and may interfere with incoming direct
connections over the Internet.

Section 4 - Troubleshooting
Troubleshooting
This
chapter provides solutions to problems that can occur during the installation and operation of the DWM-311. Read
the following descriptions if you are having problems.
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link modem (192.168.17.1 for Ethernet, 192.168.15.1 for USB), you are not
connecting to a website, nor do you have to be connected to the Internet. The device has the utility built-in to a ROM chip
in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser.
We recommend the following:
- Microsoft Internet Explorer® 11 or higher
- Mozilla Firefox 52 or higher
- Google™ Chrome 8 or higher
• If connecting over Ethernet, verify physical connectivity by checking for solid link lights on the device. If you do not get a
solid link light, try using a different cable, or connect to a different port on the device if possible. If the computer is turned
off, the link light may not be on.
• Disable any Internet security software running on the computer. Software firewalls such as ZoneAlarm, BlackICE, Sygate,
Norton Personal Firewall, and Windows® firewall may block access to the configuration pages. Check the help files included
with your firewall software for more information on disabling or configuring it.
Page 29
26D-Link DWM-311 User Manual
Section 4 - Troubleshooting
• Congure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click
the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button.
Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and re-open it.
• Open your web browser and enter the IP address of your D-Link modem in the address bar. This should open the login page
for your web interface.
• If you still cannot access the conguration, unplug the power to the router for 10 seconds and plug it back in. Wait about 30
seconds and try accessing the utility. If you have multiple computers, try connecting using a dierent computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your modem. This process will revert all your settings back to the factory defaults.
To reset the modem, follow the instructions on the next page.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. http://fsf.org/ Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

Appendix C - GPL Code Statement
Preamble
The GNU General Public License is a free, copyleft license for software and other kinds of works.
The licenses for most software and other practical works are designed to take away your freedom to share and change the
works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions
of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General
Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make
sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source
code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know
you can do these things.
To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore,
you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the
freedom of others.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the
same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show
them these terms so they know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) oer you this License giving you legal permission to copy, distribute and/or
modify it.
For the developers’ and authors’ protection, the GPL clearly explains that there is no warranty for this free software. For both
users’ and authors’ sake, the GPL requires that modied versions be marked as changed, so that their problems will not be
attributed erroneously to authors of previous versions.
Some devices are designed to deny users access to install or run modied versions of the software inside them, although
the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users’ freedom to change the
software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it
is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such
problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of
the GPL, as needed to protect the freedom of users.

Appendix C - GPL Code Statement
Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development
and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents
applied to a free program could make it eectively proprietary. To prevent this, the GPL assures that patents cannot be used
to render the program non-free.
The precise terms and conditions for copying, distribution and modication follow.
TERMS AND CONDITIONS
0. Denitions.
“This License” refers to version 3 of the GNU General Public License.
“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees”
and “recipients” may be individuals or organizations.
To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other
than the making of an exact copy. The resulting work is called a “modied version” of the earlier work or a work “based on” the
earlier work.
A “covered work” means either the unmodied Program or a work based on the Program.
To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable
for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation
includes copying, distribution (with or without modication), making available to the public, and in some countries other
activities as well.
To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with
a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently
visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work
(except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a
copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list
meets this criterion.

33D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
1. Source Code.
The “source code” for a work means the preferred form of the work for making modications to it. “Object code” means any
non-source form of a work.
A “Standard Interface” means an interface that either is an ocial standard dened by a recognized standards body, or, in the
case of interfaces specied for a particular programming language, one that is widely used among developers working in that
language.
The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the
normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable
use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available
to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window
system, and so on) of the specic operating system (if any) on which the executable work runs, or a compiler used to produce
the work, or an object code interpreter used to run it.
The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for
an executable work) run the object code and to modify the work, including scripts to control those activities. However, it
does not include the work’s System Libraries, or general-purpose tools or generally available free programs which are used
unmodied in performing those activities but which are not part of the work. For example, Corresponding Source includes
interface denition les associated with source les for the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specically designed to require, such as by intimate data communication or control ow
between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the
Corresponding Source.
The Corresponding Source for a work in source code form is that same work.

Appendix C - GPL Code Statement
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided
the stated conditions are met. This License explicitly arms your unlimited permission to run the unmodied Program. The
output from running a covered work is covered by this License only if the output, given its content, constitutes a covered
work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License
in conveying all material for which you do not control copyright. Those thus making or running the covered works for you
must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies
of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed;
section 10 makes it unnecessary.
3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an eective technological measure under any applicable law fullling obligations
under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting
circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent
such circumvention
is eected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit
operation or modication of the work as a means of enforcing, against the work’s users, your or third parties’ legal rights to
forbid circumvention of technological measures.
Page 38
35D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program’s source code as you receive it, in any medium, provided that you conspicuously
and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and
any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any
warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may oer support or warranty protection for a
fee.
5. Conveying Modied Source Versions.
You may convey a work based on the Program, or the modications to produce it from the Program, in the form of source
code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modied it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added
under section 7. This requirement modies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a
copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of
the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the
work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program
has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of
the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or
distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or
legal rights of the compilation’s users beyond what the individual works permit. Inclusion of a covered work in an aggregate
does not cause this License to apply to the other parts of the aggregate.
Page 39
36D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium),
accompanied by the Corresponding Source xed on a durable physical medium customarily used for software
interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium),
accompanied by a written oer, valid for at least three years and valid for as long as you oer spare parts or
customer support for that product model, to give anyone who possesses the object code either (1) a copy
of the Corresponding Source for all the software in the product that is covered by this License, on a durable
physical medium customarily used for software interchange, for a price no more than your reasonable cost of
physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network
server at no charge.
c) Convey individual copies of the object code with a copy of the written oer to provide the Corresponding
Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object
code with such an oer, in accord with subsection 6 b.
d) Convey the object code by oering access from a designated place (gratis or for a charge), and oer equivalent
access to the Corresponding Source in the same way through the same place at no further charge. You need
not require recipients to copy the Corresponding Source along with the object code. If the place to copy the
object code is a network server, the Corresponding Source may be on a dierent server (operated by you or
a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the
object code saying where to nd the Corresponding Source. Regardless of what server hosts the Corresponding
Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object
code and Corresponding Source of the work are being oered to the general public at no charge under
subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System
Library, need not be included in conveying the object code work.
Page 40
37D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for
personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining
whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product
received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A
product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer
uses, unless such uses represent the only signicant mode of use of the product.
“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required
to install and execute modied versions of a covered work in that User Product from a modied version of its Corresponding
Source. The information must suce to ensure that the continued functioning of the modied object code is in no case
prevented or interfered with solely because modication has been made.
If you convey an object code work under this section in, or with, or specically for use in, a User Product, and the conveying
occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in
perpetuity or for a xed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under
this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any
third party retains the ability to install modied object code on the User Product (for example, the work has been installed in
ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service,
warranty, or updates for a work that has been modied or installed by the recipient, or for the User Product in which it has
been modied or installed. Access to a network may be denied when the modication itself materially and adversely aects
the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is
publicly documented (and with an implementation available to the public in source code form), and must require no special
password or key for unpacking, reading or copying.

38D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
7. Additional Terms.
“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its
conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in
this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program,
that part may be used separately under those permissions, but the entire Program remains governed by this License without
regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or
from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify
the work). You may place additional permissions on material, added by you to a covered work, for which you have or can give
appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the
copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability dierently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specied reasonable legal notices or author attributions in that material or in the
Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modied versions of such material
be marked in reasonable ways as dierent from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnication of licensors and authors of that material by anyone who conveys the material (or
modied versions of it) with contractual assumptions of liability to the recipient, for any liability that these
contractual assumptions directly impose on those licensors and authors.
Page 42
39D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program
as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a
further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing
or conveying under this License, you may add to a covered work material governed by the terms of that license document,
provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source les, a statement of the
additional terms that apply to those les, or a notice indicating where to nd the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as
exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to
propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses
granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and nally terminates your license, and (b) permanently, if the
copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder noties you of the
violation by some reasonable means, this is the rst time you have received notice of violation of this License (for any work)
from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights
Page 43
40D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive
new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered
work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require
acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These
actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you
indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify
and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this
License.
An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing
an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party
to that transaction who receives a copy of the work also receives whatever licenses to the work the party’s predecessor in
interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work
from the predecessor in interest, if the predecessor has it or can get it with reasonable eorts.
You may not impose any further restrictions on the exercise of the rights granted or armed under this License. For example,
you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not
initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making,
using, selling, oering for sale, or importing the Program or any portion of it.
Page 44
41D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
11. Patents.
A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is
based. The work thus licensed is called the contributor’s “contributor version”.
A contributor’s “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired
or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its
contributor version, but do not include claims that would be infringed only as a consequence of further modication of
the contributor version. For purposes of this denition, “control” includes the right to grant patent sublicenses in a manner
consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor’s essential patent
claims, to make, use, sell, oer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to
enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant”
such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available
for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other
readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive
yourself of the benet of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements
of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge
that, but for the patent license, your conveying the covered work in a country, or your recipient’s use of the covered work in a
country, would infringe one or more identiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance
of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use,
propagate, modify or convey a specic copy of the covered work, then the patent license you grant is automatically extended
to all recipients of the covered work and works based on it.
Page 45
42D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are specically granted under this License. You may not
convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software,
under which you make payment to the third party based on the extent of your activity of conveying the work, and under which
the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a)
in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in
connection with specic products or compilations that contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that
may otherwise be available to you under applicable patent law.
12. No Surrender of Others’ Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy
simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not
convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to
whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely
from conveying the Program.
13. Use with the GNU Aero General Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work
licensed under version 3 of the GNU Aero General Public License into a single combined work, and to convey the resulting
work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of
the GNU Aero General Public License, section 13, concerning interaction through a network will apply to the combination
as such.
Page 46
43D-Link DWM-311 User Manual
Appendix C - GPL Code Statement
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time.
Such new versions will be similar in spirit to the present version, but may dier in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program species that a certain numbered version of the GNU
General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of
that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify
a version number of the GNU General Public License, you may choose any version ever published by the Free Software
Foundation. If the Program species that a proxy can decide which future versions of the GNU General Public License can
be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the
Program.
Later license versions may give you additional or dierent permissions. However, no additional obligations are imposed on
any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY
AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS
WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY
OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal eect according to their
terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection
with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
