Functioning of the device
Functioning of the deviceFunctioning of the device
Functioning of the device
The WEB-Catcher transmits and receives the WIFI signals in a flat, circular cone
(donut) in an angle of 8-20° depending on the type of the antenna. This specific
characteristic considerably increases the range of communication (transmission and
reception power).
You do not need a long HF antenna cable due to the direct connection of antenna
and WLAN electronics. Thus there is no loss of the maximum possible transmission
and reception power. Therefore the range of communication can be 50 times higher
than that of the integrated systems in notebooks. The radiation power of the
antenna can be adjusted in the router set up:
• Type: SW08WL up to 35,5dBm (3548,13mW)
• Type: SW10WL up to 37dBm (5110mW)
• Type: SW12WL up to 39,5dBm (8912,50mW)

5. Positioning of antenna
5. Positioning of antenna5. Positioning of antenna
5. Positioning of antenna
If you install the antenna in vertical position in unobstructed sight of the
WLAN hotspot, you will get the best horizontal communication range.
A wrong installation of the antenna will substantially reduce the maximum possible
communication range.
Please also note that a high difference in altitude between hotspot and antenna may
cause a bad connection or a total loss of the connection.
Any obstruction between antenna and hotspot weakens the WLAN waves by
reflection or deviation. Therefore an optimal position of the antenna is essential for a
good WLAN connection.
Paper, cardboard, textiles, glass, wood, thin plastics and dry leaves are relatively
permeable to WLAN waves whereas metal, roof tiles, soundproof windows and
thermo glass and especially ferroconcrete are hardly permeable.

Transmission and radiation power
Transmission and radiation powerTransmission and radiation power
Transmission and radiation power
10.1 Regulations concerning the maximum transmission power
According to regulations in the EU and many other
countries (EU: RTTE regulation) the radiation power
(EIRP - Equivalent Isotopic Radiation Power) of a
WLAN device must not exceed 20 dBm / 100mW.
The radiation power of a WLAN device is the sum of
the transmission power of the router and the
antenna gain. In order to calculate the radiation
power of the WLAN device all power and
attenuation levels in dBm must be known. See
calculation example below.
If you use your device outside the EU, observe the
national regulations of the country in question. In
the US, for example, EIRP is 1000mW / 30dBm.
In case the legal radiation power is exceeded, the
producer refuses any liability obligations!
Example:
+ 10,0 dbm (transmission power WLAN-device)
+ 10,0 dbi (antenna gain)
= 20 dbm radiation power EIRP
Converting dBm to mW / mW to dBm
mW in dBm = 10Log10(Watt) + 30
dBm in mW = 10(dBm/10)

SW08WL | SW10WL | W12WL
10.2 Adjusting WLAN transmission power
In order to adjust the transmission and radiation power of your WEBcatcher antenna you must click on the tab "Advanced" and further down
under the menu item "wireless settings" on the button "Advanced".
In the input window "TX Power" the transmission power of the WLAN
electronics can be set from 3 to 27dBm. .
On delivery the transmission power is set on 8dBm to keep the legal
radiation power limit of 20dBm (for type SW12WL).
SW12WL: 8dBm + 12dBi = 20dBm
After input of the transmission
power click on "Apply".
For the antennas 8dBi and 10dBi the transmission power can be set 10 or
12 dBm to receive the permitted 20dBm.

In the following we will explain the most important technical terms used in our manual. If
you want more detailed information, we recommend electronic technical literature.
IEEE 802.11 Standard
802.11 refers to an industrial standard that clearly regulates and harmonizes regulations
for transmitting network devices.
Categories like 802.11b or 802.11g determine a fixed frequency range for radio
transmission and its speed etc.. Currently the most common standard used is IEEE
802.11g with a speed of up to 54 MBit/s.
The standards are edited by the Institute of Electrical and Electronics Engineers (IEEE).
Access Point
is a network device that establishes a permanent connection between wired and wireless
networks. In most cases an access point connects the connected computers with the
internet -to say it quite simplified.
Ad Hoc
An Ad-Hoc wireless LAN is a group of computers equipped with WLAN adaptors that are
connected to an independent wireless LAN. Unlike an infrastructure network, this makes
a direct connection between computers without access to the internet possible
DHCP
Dynamic Host Configuration Protocol is a mode by which the server automatically
allocates IP addresses to network users. DHCP is used to automatically allocate IP
addresses. It requires a DHCP server in the network assigned with this task.
Direct Sequence Spread Spectrum
This method uses wireless adaptors to transmit data via the frequency spectrum. An
alternative method is frequency switching. With the direct sequence method data are
spread by one channel whereas frequency switching means that channels on a narrow
frequency band are switched several times per second.
ESSID
is an infrastructure configuration that can also support roaming for mobile staff. If there
are at least two BSS (broadband switching system), they can be configured as Extended
Service Set (ESS). Users within the can communicate with each other while the
connection to the stations of the wireless network is maintained.
Access Points within the ESS must be configured by the same BSS and channel.

Ethernet
is a 10/100-Mbps-network that is used for private home or office LAN cable connections.
Users must always be connected to the network to have access to this net.
Gateway
is a device two different systems with each other, e.g. a LAN and a computer. The
internet terminology defines a router as gateway. A gateway normally functions as a kind
of funneling system for all internet contacts.
Infrastructure
Integrated wireless and wired LANs are called infrastructure configurations. In a lot of
companies this infrastructure is used to provide wireless access to the central database
and the wireless connection of the mobile staff.
ISM-Frequenzband
Die FCC and related organizations outside the US have reserved a frequency range that
may be used (without any license fee) for industrial, scientific and medical purpose for
which the spectrum used worldwide is about 2.4 GHZ. This provides users all over the
world with high speed, wireless access to the internet..
Local Area Network (LAN)
A LAN consists of several computers which are all equipped with a suitable network. They
are connected either via cable or wireless enabling them to use applications, data and
peripheral devices together. Connections are made by cable or wireless devices, no
telephone lines are used. A LAN is useful to connect WLAN devices on premises,
university campuses, railway stations etc.
Network
is a system of connected computers. This network can transmit data, files and news.
Networks can be established locally or for wider areas (WAN).
Protocol
is a standardized set of rules that determines how data are transmitted, including the
format, chronological sequence, sequencing and/or check of errors.
Roaming
In an infrastructure network roaming refers to the process when a wireless connected
notebook switches from the first access point to another access point establishing a new
connection.
In a network environment in which access points are used PCs can always be connected
regardless of their position or provider.

SSID
is a network identification that is unique for every network. Only clients and access points
sharing the same SSID can communicate with each other. Mind upper and lower case in
the characters.
Simple Network Management Protocol (SNMP)
is the network management protocol of TCP/IP. In the SNMP hard- or software agents
monitor the activities of various devices in the network and report them to the networkconsole-workstation. Control information about any device is administrated in a structure
called management-information block.
Static IP addressing
is a process to allocate network IP addresses to clients. In networks with static IP
addressing the network administrator allocates an IP address to every computer. Having
allocated a static IP address the computer uses the same address every time it is started
and registered unless the address has been manually altered.
Temporal Key Integrity Protocol (TKIP)
The Temporal Key Integrity Protocol is part of the IEEE 802.11i encryption standards for
wireless LAN. TKIP is the generation following the WAP (Wired Equivalency Protocol)
which is used for the security of wireless 802.11-LAN. TKIP provides a data encryption
changing after any data packet and offers a message integrity check and a rekeying
mechanism that remedies the security vulnerability of the WEP. .
Transmission Control Protocol / Internet Protocol (TCP/IP)
is a pile of protocols that were developed by the Advanced Research Projects Agency
(ARPA). It is often used for company intranets as it is very well suited for WLAN. TCP
determines how packets are sequenced for transmission in the network. The term TCP/IP
is often used to refer to the complete pile of related protocols.
Transmission/Reception
refers to the throughput of a wireless connection in bytes per second. It is always
calculated for the period of two seconds.
Wi-Fi Alliance
is a non-profit international association that was established in 1999 to certify the
interoperability of wireless LAN products on the basis of IEEE 802.11 . The target of the
association is to improve the interoperability of products for the users. Previously the
organization was called WECA.

Wi-Fi Protected Access (WPA)
The Wi-Fi Alliance developed WPA as a method of encrypting data for wireless 802.11LAN. WPA is an industry led, not yet standardized version of 802.11i that uses the TKIP
which (among other features) remedies the security vulnerability of the WEP by the use
of dynamic keys.
Wide Area Network (WAN)
A WAN consists of several LANs that are connected by telephone lines and/or glass fiber
optic cable. WAN may cover the area of a town, a state, a country or of even the whole
planet.
Wired Equivalent Privacy (WEP)
Meanwhile it is generally accepted that WEP, a method to encrypt data protecting the
transmission between 802.11 clients and APs is insufficient. It used the same key for all
communication devices. The problems of WEP are well-known, among others there is an
insufficient length of keys as well as the lack of an automatic method to allocate the
keys. WEP can easily be decrypted with standard tools within a few hours..
Wireless LAN (WLAN)
A wireless LAN doesn't use cables but radio waves or infrared technology to transmit
data. High frequency and infrared connections are the most used modes of wireless
connections. Most wireless LANs use spread spectrum technology. This technique offers a
limited spectrum (usually less than 11Mbps) that is used by users with other devices in
the spectrum. Users can operate a device with spread spectrum technology without
having a license of the FCC.
