Installation
Preparation for Installation
Always double check for any missing parts from the kit you received before deployment.
The next step is to set up the computer Ethernet interface for configuring the TT5800/TT2400. Since the default IP
Address of the unit is on the 192.168.10.x IP range in both Client Bridge and AP mode you will need to set the Ethernet
interface within the same IP range, where x will have to be a free IP address number from 1-254.
Check the following section - “Hardware Installation” and the next chapter - “Configuring Windows for IP Networking” to
obtain complete details.
Hardware Installation
Follow the procedure below to install your TT5800/TT2400 device:
1. Select a suitable place on the network to install the TT5800/TT2400. For best wireless reception and
performance the external antenna should be positioned within Line of Sight from the AP with proper alignment.
2. Connect the TT5800/TT2400 to the ODU side of the PoE Injector, via a straight Ethernet cable (Cat-5), and then
connect the NET side of the PoE Injector to either a computer or an Ethernet Switch. Note: The TT5800/TT2400
now fully supports the MDI/MDI-X standard and no longer requires the use of a cross over cable to connect
directly with a computer.
3. Connect the 48VDC power adapter to the power jack on the PoE injector to power on the TT5800/TT2400.
4. Check the LEDs on the TT5800/TT2400 to confirm if the status is okay. At this point the Power (PWR) LED
indicator should be red and Ethernet (LAN) LED should be green. The RF light should light up once the unit is
associated wirelessly with another wireless device. However at this point the unit is still in factory default setting
so do not be alarmed that the WLAN light doesn’t light up.
5. Now the hardware installation is complete and you may proceed to the next chapter –“Configuring Windows for
IP Networking” for instructions on setting up network configurations.

Information
Under the main web interface home page you will see the following configuration menu pages: Information, APs,
Wireless, Security, Admin and Advanced. Detailed information for each section is provided below:
Access Points (APs)
The APs section displays available hotspots in the area along with the MAC address, SSID, Channel, Wireless mode,
signal strength and transmission rate for each access point.
14
Wireless
15
Wireless On/Off
This is the on/off switch of the radio card.
Wireless Mode
Infrastructure: An 802.11 networking framework in which devices communicate with each other by first going through
an Access Point (AP).
Ad-hoc: An 802.11 networking framework in which devices or stations communicate directly with each other, without
the use of an access point (AP). Use this mode if there is no wireless infrastructure or where services are not required.
Wireless Network Name (SSID)
Network Name is also known as SSID, which stands for Service Set Identifier. Any client in Infrastructure mode has to
indicate the SSID of an Access Point to access a service such as internet access through the Access point.
Access Point Identifier (BSSID)
The Basic Service Set Identifier is the unique identifier (MAC address) of an access point in a Basic Service Set (BSS)
network. The subscriber unit is forced to associate with this particular unit if there are multiple access points in the
network.
Transmission rate (Mbits/s)
This option indicates the transmission rate of the bridge. Specify the rate according to the speed of your wireless
network from the list. Most of the time the default setting, Best (automatic), should be selected for best performance.
The setting can be adjusted manually if the link quality and signal strength are unusually low or high to get the best
performance.
802.11 Mode
Wireless mode allows the user to select whether this subscriber unit will connect to an 802.11b only network, an
802.11g only network, an 802.11a only network or both b/g networks. For b or g only wireless devices on the network,
selecting 802.11b or 802.11g only mode will provide better performance than mixed mode. In the case of TT5800 only
802.11a mode is allowed. For TT2400 the options of 802.11b, 802.11g only or Mixed 802.11g and 802.11b are
available.
RF Transmit Power
This section controls the power output for the mini-PCI radio card. The valid input range for this section is in the range
of 0-30 in dBm units or (1mw – 1000mw). The default value is 23 dBm or 200mW.
Super Mode
Super Mode is only supported if both the client and the AP are using compatible Atheros radio chipsets
• Disabled
• Super A/G without Turbo
• Super A/G with Static Turbo
• Super A/G with Dynamic Turbo (AR enabled)
16
Country and Region
This option selects the country and region of operation. Every device should be configured to use the proper regional
settings which comply with and do NOT violate the radio regulatory laws at the installed location.
Channel
Channels are important to understand because they affect the overall capacity of your Wireless LAN. A channel
represents a narrow band of radio frequency. A radio frequency modulates within a band of frequencies; as a result
there is a limited amount of bandwidth within any given range to carry data. It is important that the frequencies do not
overlap or else the throughput would be significantly reduced as the network sorts and reassembles the data packets
sent over the air.
For the TT2400: 2.4 GHz – 2.497 GHz frequency range, there are only 3 channels out of the 11 available that do not
overlap with one another. To avoid interference within a network with multiple APs, set each AP to use one of the 3
channels (e.g. Channel 1) and then the other AP to be one of the other 2 channels (i.e. Channel 6 or Channel 11)
within the range of the wireless radio. This simple method will reduce interference and improve network reliability.
802.11b/g Wireless Channel Frequency Range: 2.4 GHz – 2.497 GHz
802.11b/g Non-overlapping Channel Frequency Ranges
• Channel 1 = 2.401 GHz – 2.423 GHz
• Channel 6 = 2.426 GHz – 2.448 GHz
• Channel 11 = 2.451 GHz – 2.473 GHz
Americas: Wireless Channels 1 – 11
Asia: Wireless Channels 1 – 14
Europe: Wireless Channels 1 – 13
802.11a Wireless Channel Frequency Range: 5.15 GHz – 5.35 GHz, 5.725 – 5.825
802.11a is an extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band.
802.11a uses an orthogonal frequency division multiplexing encoding scheme rather than FHSS or DSSS. Unlike that
of 802.11b/g, 802.11a standard separates its channels into 3-100MHz segments in the US.
The lower and middle band accommodates 8 channels in a total bandwidth of 200 MHz and the upper band
accommodates 4 channels in a 100 MHz bandwidth. The frequency channel center frequencies are spaced 20 MHz
apart. The outermost channels of the lower and middle bands are centered 30 MHz from the outer edges. In the upper
band the outermost channel centers are 20 MHz from the outer edges.
In addition to the frequency and channel allocations, transmit power is a key parameter regulated in the 5 GHz U-NII
band. Three transmit power levels are specified: 40 mW, 200 mW and 800 mW. The upper band defines RF transmit
power levels suitable for bridging applications while the lower band specifies a transmit power level suitable for shortrange indoor home and small office environments.
802.11a Non-overlapping Channel Frequency Ranges
Lower Band (5.15 - 5.25 GHz) – Maximum Output Power 40mW
• Channel 36 = 5.15 – 5.18
• Channel 40 = 5.18 – 5.20
• Channel 44 = 5.20 – 5.22
• Channel 48 = 5.22 – 5.25
Middle Band (5.25 - 5.35 GHz) – Maximum Output Power 200mW
• Channel 52 = 5.25 – 5.28
• Channel 56 = 5.28 – 5.30
• Channel 60 = 5.30 – 5.32
• Channel 64 = 5.32 – 5.35
17
Upper Band (5.725 - 5.825 GHz) – Maximum Output Power 800mW
• Channel 149 = 5.725 – 5.745
• Channel 153 = 5.745 – 5.765
• Channel 157 = 5.765 – 5.785
• Channel 161 = 5.785 – 5.805
• Channel 165 = 5.805 – 5.825
Special Atheros Turbo Mode Channels
*Use this setting only when both side of the wireless connection is using the Atheros chipset. The radio will combine 2
free channels for the wireless transmission to double the bandwidth.
• Channel 42 = 5.210
• Channel 50 = 5.250
• Channel 58 = 5.290
• Channel 152 = 5.760
• Channel 160 = 5.800

Security
19
WPA Configuration
Short for Wi-Fi Protected Access, WPA is a Wi-Fi standard that was designed to improve upon the security features of
WEP. WPA has the following improvements over WEP:
• Improved data encryption through temporal key integrity protocol (TKIP). TKIP scrambles the keys using a
hashing algorithm. By adding an integrity-checking feature, TKIP ensures that keys have not been tampered
with.
• User authentication through the Extensible Authentication Protocol (EAP). WEP regulates access to a wireless
network based on a computer’s hardware-specific MAC address, which is relatively simple to be sniffed out
and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized network
users can access the network.
WPA Enable
This option enables the WPA Authenticator. Note that any client that does not support the WPA standard will not be
able to handshake / authenticate with a WPA enabled device.
WPA Mode
• WPA
• WPA2
o Designed to secure present and future versions of IEEE 802.11 devices, WPA is a subset of the IEEE
802.11i specification. WPA addresses all known vulnerabilities in WEP. WPA also provides user
authentication, since WEP lacks any means of authentication. WPA replaces WEP with a strong new
encryption technology called Temporal Key Integrity Protocol (TKIP) with Message Integrity Check
(MIC). It also provides a scheme of mutual authentication using IEEE 802.1X/Extensible
Authentication Protocol (EAP) authentication or pre-shared key (PSK) technology. WPA was designed
and has been scrutinized by well-known cryptographers. It can be implemented immediately and
inexpensively as a software or firmware upgrade to most existing Wi-Fi CERTIFIED™ access points
and client devices with minimal degradation in network performance. WPA offers standards-based, WiFi CERTIFIED security. It assures users that the Wi-Fi CERTIFIED devices they buy will be crossvendor compatible. When properly installed, WPA provides a high level of assurance to enterprises,
small businesses and home users that data will remain protected and that only authorized users may
access their networks. For enterprises that have already deployed IEEE 802.1X authentication, WPA
offers the advantage of leveraging existing authentication databases and infrastructure.
o WPA2 is the second generation of WPA security; providing enterprise and consumer Wi-Fi® users with
a high level of assurance that only authorized users can access their wireless networks. Launched in
September 2004 by the Wi-Fi Alliance, WPA2 is the certified interoperable version of the full IEEE
802.11i specification which was ratified in June 2004. Like WPA, WPA2 supports IEEE 802.1X/EAP
authentication or PSK technology. It also includes a new advanced encryption mechanism using the
Counter-Mode/CBC-MAC Protocol (CCMP) called the Advanced Encryption Standard (AES). AES
satisfies U.S. government security requirements. It has been adopted as an official government
standard by the U.S. Department of Commerce and the National Institute of Standards and
Technology (NIST). Organizations that require the AES encryption available in WPA2 should be aware
that upgrading to it may require new hardware. Section II of this document offers a roadmap for
organizations planning to upgrade to WPA2. Considerations for its deployment are outlined in Section
III.
