FCC REGULATORY ALERT
Regulatory Alert
As of July 20, 2007, a new FCC regulation has gone into effect which impacts operators of
the U-NII band in the United States. As a result of this regulatory change, several MicroTek
products are affected. The new FCC regulation impacts the sale of wireless equipment in the
5.25-5.35 GHz band. The regulation states that all devices imported and marketed after the
July 20
th
, 2007 deadline must support radar detection as specified by the FCC in the 5.25-
5.35 GHz band.
MicroTek Electronics Product Changes
To comply with FCC regulation, MicroTek has disabled the 5.25-5.35 GHz band. The
following products are still available but will only support operation in the 5.725-5.85 GHz
ISM band.
ML WES-2500
ML WES-2-4
ML WAP
ML WAPOM
ML WSU
ML WSUP
ML WSUOM
ML WES-D
ML WES-OD
ML WES-D1-2
MicroTek is currently working on the firmware change necessary to comply with the new
FCC regulations which require Dynamic Frequency Selection (DFS) and Transmit Power
Control (TPC) for operation in the 5.25-5.35 GHz band.
How Does the FCC Regulation Affect the WES User?
If one WES System is in use and there are no plans to add to the wireless project then it
might not affect you at all. However, if you are using two or more systems then you may
need to change frequencies according to the available channels. Multiple WES systems set to
channels 0, 1 or 2 (all unavailable 5.2/5.3 GHz frequencies) will all be defaulted to channel 3
(available 5745 MHz). The next available frequency in sequence would be channel 4 (5765
MHz). Channels 3 through 7 are all individual frequencies but channels 0-2 are not available.
