The Radwin 2000B was just recently released and is already flying off the shelf. This is the first true carrier grade wireless bridge to hit this price point. The Radwin 2000B operates in the entire 5GHz band, uses MIMO technology, provides low latency and comes in a convenient form factor. The 2000B comes with both an integrated 15 dbi antenna as well as 2 x N-Connectors in case of a longer path.
More and more 3.65 GHz wireless products are rolling out of manufacturing and R&D and are hitting the shelves. Here is a highlight of three 3.65 GHz point to point solutions both released or soon to be released.
Radwin RW-2030-0100 : 3.65 GHz carrier grade 200 Mbps point to point bridge. This device is an outdoor unit (ODU) with an integrated 21 dbi antenna and the ability to send TDM (T1) over the wireless link. The Radwin has adaptive modulation and spectrum analyzer built in and is built tough for demanding applications.
Ubiquiti has 2 solutions here, the PowerBridgeM365 and the RocketM365 with additional dishes. Unlike the Radwin these products are based on traditional Atheros WIFI chipsets which greatly reduce the cost of the items but do come with additional overhead and quirks that Radwin’s proprietary protocols can avoid.
PowerBridgeM365 : To be released Q1 of 2011 the PowerBridge M365 is Ubiquiti’s attempt at a carrier grade bridge. Not much (actually no) info is really given about the PowerBridgeM365 but, from what we are told, the current PowerBridgeM5 offers a nice mix of price & performance. So we are interested in seeing what the new M365 can do.
RocketM365 + RocketDish-3G26 : The Rocket is a very versatile device. You can select between AP and Bridge mode and comes with 2 x RP-SMA connectors that will allow you to connect it to either a sector (AP) or dish antennas (bridge).
The new Ubiquiti PowerBridge M5 is directly targeted at WISPs who need the increased capacity between towers but whos wallets are tight. The PowerBridge features a unique 25dbi MIMO antenna array that Ubiquiti claims will support links up to 20 miles with 100 Mbps+ throughput. I do find that a little hard to believe as you would normally need an external antenna to sustain such throughputs at that distance so if you have any feedback on actual throughputs we’d love to hear it!
The PowerBridge M5 comes at a price of $269 per end or $538 for a complete link.
Motorola is releasing their first every outdoor dual radio 802.11n mesh access point the AP-7181. With innovative antenna array design the AP-7181 will provide longer distances and better performance then standard mesh APs with simple “stick” or “dipole” antennas.
