Proxim Does Dynamic Frequency Selection



Proxim Wireless, today announced that it has received FCC certification for the Dynamic Frequency Selection (DFS) capabilities of its Tsunami MP.11 point-to-multipoint products.

This new certification means that Proxim’s Tsunami MP.11 Model 5054-R (pdf) and Tsunami MP.11 Model 5012 (indoor and outdoor subscriber units), now enable FCC-compliant operation in each of the 5.3 GHz, 5.4 GHz and 5.8 GHz bands in the U.S. and Canada in a single radio.

DFS is a recent FCC requirement for operation in the 5.3 GHz and newly available 5.4 GHz bands. As a result, these products expand the frequencies available on one unit. proxim says DFS is one of many new capabilities enabled by their new Tsunami MP.11 software release 4.0. Proxim’s Tsunami MP.11 family enables wireless point-to-multipoint connections in the 900 MHz, 2.4 GHz, 4.9 GHz and 5 GHz frequency bands using Proxim’s Wireless Outdoor Routing Protocol (WORP).

The mid-band adds another 255 MHz and 11 channels to the existing 325 MHz and 13 (20 MHz-wide) channels currently available for unlicensed use. The FCC opened up the middle band (from 5.470 GHz to 5.725 GHz) of the 5 GHz Unlicensed National Information Infrastructure (UNII) band for unlicensed use in the United States, but requires Dynamic Frequency Selection to avoid interference.

Dynamic Frequency Selection, shifts client and access point radios to a different channel if it detects, say, a radar transmission, and will automatically adjust the strength of the radio signal to increase or decrease the coverage area.
