900 MHz Up/Down Converter with Power over Ethernet for 2.4 GHz radio


Teletronics announces its 900 MHz Up/Down Converter with Power over Ethernet for 2.4 GHz radio to extend the range with Near Line-of-Sight.

Rockville, MD – November 22, 2004

Teletronics International, Inc. announces a new product, 900MHz Up/Down Converter with Power over Ethernet (POE) that works with any 2.4 GHz radio for readily in-the-air transmission at 900MHz. This product has two versions, UDC9001 (Up/Down Converter 900 MHz 1 Watt) and UDC9002 (Up/Down Converter 900 MHz 2 Watt).

The new 900 MHz broadband product will add to Teletronics’ existing radio product portfolio that supports 2.4 GHz and 5.8 GHz frequencies. This product will allow a link at 900 MHz to be established over distances in excess of 20 miles depending on conditions with a Near Line-of-Sight (NLOS).

Unlike 802.11a/b/g standards, there is no standard applicable to 900 MHz radios, significantly hindering the market prospects of proprietary 900 MHz radios. Teletronics’ approach of using UDC with a 2.4 GHz radio creates a new prospect because:

1. It provides not only Line-of-Sight (LOS) but Near Line-of-Sight (NLOS) coverage at 900 MHz
for increased range beyond those of existing systems.

2. It works with both 802.11b/g standards, although the 802.11g mode provides the better performance.

3. It is easy to upgrade and add new features in the 802.11 standard such as QoS in the future without investing additional R/D dollars.

4. It works with Teletronics Ezbridge, Versa Routers, and other outdoor 802.11b/g products, all are robust, low-cost equipment.

“In addition to low cost and extended range,” said Dr. Dickson Fang, President of Teletronics, “we believe our 900 Mhz customers will now enjoy the tremendous business advantage of claiming their system as a part of the main stream of 802.11, eligible for all kinds of broadband wireless applications.”
