Because of the difference in power limitations, data rate
requirements, applications, environmental conditions
and performance objectives, not all of Teletronics' point-to-point
systems are identical. For each customer,
pre-installation design and on-site surveys are made in advance
by Teletronics per the customer's request.
A suggested equipment list and setup configuration are submitted
for approval by the customer prior to
Teletronics undertaking any work. Generally, the first few
links of Teletronics' point-to-point systems are installed
by our professional staff. From a hardware installation viewpoint,
Teletronics essentially provides transceiver
equipment and antennas positioned on customer-supplied towers
or poles to effect clear line of sight paths.
The two antennas of the point-to-point system are aimed at
each other to optimize the wireless connection
between the links.
For a new point-to-point system customer, Teletronics will
first connect a Teletronics EZWiMax system to the
customer's indoor network by a cable and a connector then
proceed with a trial and subsequent calibration
to prove connectivity before turning the system over to the
customer for operation. Using multiple systems,
customers can connect more than two locations to form an expanded
network. After the first few links are
established by Teletronics, including trials, demonstrations
and training, the customer will then take over
subsequent installations and begin operation of the system.

All TT™ Series products are designed for outdoor, all-weather
deployment and offer a robust yet stylish
weather-proof case that will stand up to the harshest environments.
TT™ Series products all have integrated
transparent VLAN, QoS, bandwidth control, WPA, WPA2, 64/128
bit WEP data security, MAC filtering and Web
and SNMP features. New NAT functionality will be incorporated
soon into the products.
TT™ Series products cover 802.11a, b, and g at frequencies
of 5.8GHz and 2.4GHz. Of special note is Teletronics'
TT™5800 bridge/router, or the TT™X. FCC approved
at 200 mw power for 5.8GHz long-distance applications, the
TT™5800 can be configured either as a base-station or
as a client station. "We were able to put the TT™5800
through
various tests during the last three weeks and the results
were quite unbelievable despite my vast experience in
this field over time" remarked Mr. Yomi of InterFinish,
an ISP customer of Teletronics’, "We were able
to get 19.5
miles point-to-point with the 28dBi flat panel antenna and
15 miles on the 22dBi antenna. Both links are steady at
24Mbps throughput and a latency of 1ms between the two radios,
even when fully loaded with data."
Recognizing the merit of the TT™5800, AETC of China
invited Teletronics to enter a bidding to become the supplier
of a broadband wireless network for 60 schools in late 2005.
Teletronics won the bid, completing the project in
June, 2006. Essentially, the project was for the installation
of wireless broadband systems at 5.8GHz to serve approximately
50,000 students in 60 schools across Dang Tu County, a municipality
covering an area of 100
square kilometers near Nanjing, China. For those who cannot
wait for WiMax either because of cost or timing,
Teletronics' EZWiMax products offer a reliable and cost-effective
alternative.
