The Alvarion (Breezecom) BreezeACCESS are a series of ISP radio released in the 1998-2004 time frame based on 802.11 FHSS. Origially there was BreezeAccess II for 2.4 GHz, and then BreezeACCESS V for 5GHz, and 900 for 902-928 MHz. They use a 1 MHz wide channel with GFSK modulation (2MHz on 900) and can do about 1.6 Mbit/s payload throughput at a signaling rate of 3mbit/s. The system supports about 550 packets per second.

These were the high-end technology for WISP's in the 2000's. They supported native voice, or prioritization based on 802.3p bits. Using the native voice hardware they supported a CAC on each sector/access point (an Access Unit or AU in Alvarion nomenclature). Each unit supports CIR/MIR and some filtering to help with people turning their router backwards. There's a detailed security model and they are designed to operate in a vlan aware network.

There's a less fully featured LAN soultion based on the SU-I hardware known as Breezenet. This lacks telnet management and is somewhat compatible with the over the air format, but will not respect MIR/CIR or other features in the ISP CPE.

Note this is not the same as BreezeACCESS VL, which is based on the OFDM atheros chip set.

Why use these?

Well they are 20 years old? What good are they?

They are cheap, and available on the market for 10-20 per unit.

They can be programed to use a single frequency, or a defined hopset.

You can convert the SU to an AU.

Easy to amplify as they will work with any amp that works with DMR/TRBO.
