Installation
Preparation for Installation
Always double check for any missing parts from the kit you received before deployment.
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’ll need to set the computer Ethernet
interface within the same IP range, where the 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), 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 require the use of 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 and Ethernet
LEDs should be on green. The WLAN 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 the 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 instruction 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, Advanced. Check below for detail information on each section.
APs
The APs section will display the available hotspots in the area along with the MAC address and some basic RF related
information.
Wireless
Wireless On/Off
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 a Access Point to start accessing the service from behind such as internet access.
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.
You may want to adjust the setting manually If your link quality and signal strength is usually low or high to get the best
performance.
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. The default value is 23 dBm or 200mW.
802.11 Mode
Wireless mode allows the user to select whether this Bridge will connect to an 802.11b only network, an 802.11g only
network, an 802.11a only network or both b/g networks. If you only have b or g wireless devices on the network
selecting 802.11b or 802.11g only network will provide better performance then in 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 is
available.
Super Mode
Super Mode is only supported if both the client and the AP is 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)
Auto Channel Select
Check this box to enable Access Point to automatically select the best channel at start up. This may take upto 20
seconds and no clients will be able to associate during this period.
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 lowered as the network sorts and reassembles the data packets
sent over the air.
These are the only 3 channels out of the 11 available that do not overlap with one another. To avoid interference within
the 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 separate its channels into 3 100MHz segments in the US.
The lower and middle band, accommodate 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.
