The RADWIN product family focuses on the delivery of wireless Ethernet over large distances. Now including both the WinLink 1000 and RADWIN 2000 series devices, the products are targeted to such uses as IP or WiMAX backhauls, multi-site connections in Enterprise campuses, or broadband service delivery for providers. The products are sold in pairs; i.e., a WinLink or RADWIN is deployed at both ends of the connection.

The WinLink 1000 product line aggregates both T1/E1 and Ethernet services and delivers them over distances of up to 50 miles to the recipient radio. The key entry in the WinLink portfolio is the WinLink 1000, which consists of an indoor unit (IDU) which connects via CAT-5e cabling (100 meters max) to an outdoor unit, which is offered with an integrated antenna or with the ability to connect to an external antenna.

As of this writing, three different IDU devices are offered by the vendor: The IDU-E, a half-rackmount device with up to 2 Ethernet (10/100) ports and up to 2 T1/E1 interfaces; the IDU-C, with dual Ethernet ports (10/100) and 4 T1/E1 interfaces; and the IDU-R, which includes a single T1/E1 port, dual 10/100 ports, and an external alarms interface. The IDU-R is specifically targeted for back-up deployments: It connects to the remote IDU-R via a physical T1/E1 line, which it constantly monitors. If that physical line should fail, it automatically switches to the radio link, instead.

For outdoor units, multiple frequency bandwidths are supported; including 2.300-2.690GHz, 4.940-4.990 GHz, and 5.140-6.020 GHz.

A key feature of the WinLink platform is its support for multiple point-to-point (MPtP) deployments, in which multiple WinLink devices can be deployed at the same site, enabling it (the site) to serve multiple remote connections. Facilitating this type of deployment is the vendor's Hub Site Synchronization (HSS) technology, which the vendor states synchronizes the transmissions of the multiple WinLink radios, removing the mutual interference that would otherwise occur from a multi-radio collocation. With MPtP up to 16 WinLink 1000s can be deployed at a single site.

An additional WinLink model, the WinLink 1000 Access, is targeted specifically to Ethernet point-to-point connections (no T1/E1 connectivity). The WinLink 1000 Access IDU includes a single 10/100 port that can deliver power (via PoE) to the ODU, with overall link throughput listed at up to 2 Mb/sec (full duplex). The WinLink 1000 Access platform operates in the 2.300--2.4835, 2.400--2.4835, or 5.725--5.850 GHz frequency bands.

New to the vendor's product family are the RADWIN 2000 series radios, which they boast support transmissions at up to 50 Mb/sec (full duplex) and ranges of up to 75 miles. Similar to the WinLink 1000s in package (an IDU or PoE device connects via CAT-5e cable to an ODU, which is offered with either an integrated antenna or supporting connections to an external antenna), the RADWIN 2000s are expected to operate in the 4.9--5.8 GHz bands and leverage a "Combo" design in which multiple frequencies are supported in a single unit; such that the frequencies can be switched as needed in noisy environments. Initially available only for Ethernet, the vendor states that RADWINs with TDM interfaces are expected to be available in the first half of 2009.

The WinLink and RADWIN series products are available now. Contact RADWIN for further information.
