The solution allows Lans to be connected - as long as they have line of sight - using Alvarion's Breezelink wireless transmission equipment in conjunction with RAD's Kilomux 2100 multiplexer, which compresses voice traffic and transmits it along with data and fax traffic.
The solution gives a full duplex bandwidth of 384kbps and is aimed at businesses that want to connect separate Lans across urban or rural areas, especially where broadband offerings such as ADSL are not available.
The equipment operates in the industrial, scientific and medical 2.4GHz frequency band, which is unlicensed in the UK. The Kilomux multiplexer allows a number of offices to use a single private branch exchange.
Grant Notman, UK general manager at RAD Data Communications, said potential users would need to install the Alvarion dish on the outside of their building and connect that via the multiplexer to their Lan. This would allow three or four voice calls - compressed from 64kbps to 6.4kbps - as well as 256kbps for the Lan.
The Kilomux uses time-division multiplexing to ensure minimal delay and protocol transparency. It connects to leased line, ISDN, Fractional E1/T1, fibre and IP.
