Amended from Broadband Wireless Magazine:
 Radwin enhanced its WinLink 1000 product family by adding a new wireless broadband system supporting the 4.9 GHz public safety band.
The WinLink 1000 product for the 4.9 GHz frequency band is designed to
provide secure high-speed data communications for police, fire and
other public safety workers.
The product supports data transport at E-1/T-1 speeds, enabling voice
and data backhaul, broadband access and multi-site connectivity. The
system delivers high capacity data at distances of up to 80 kilometers
(49.7 miles), according to an announcement issued by the company.
More from Daily Wireless:
A maximum Effective Radiated Power (ERP) of up 16W
can be used at 4.9 GHz. There are 18 channels which are aggregated for
channel bandwidths of 1, 5, 10, 15, or 20 MHz. Channels 1 – 5 and 15-18
are 1 MHz channels and 6-14 are 5 MHz channels. Power limits vary from
20 dBm to 33 dBm depending on bandwidth.
Other 4.9GHz vendors include AIRAYA which is shipping FCC type-approved 4.9GHz public safety outdoor bridges. Mesh is often used at 4.9 GHz since the higher frequency requires three times the density of nodes as the 2.4 GHz band.
