ArrayComm nabs spectrum for i-Burst 3G

Newcomer mobile carrier, ArrayComm will use its i-Burst wireless system technology to deliver its third-generation (3G) network within Australia's capital cities.

ArrayComm subsidiary CKW Wireless secured 5MHz of unpaired spectrum within all capital cities at the recent Australian Communications Authority (ACA) auction of 15-year licences in the 2GHz band.

ArrayComm, provider of smart antenna-based wireless communications, said i-Burst will deliver the 3G services via an IP-centric wireless Internet access network with an aggregate bandwidth of 20Mbps per call.

"We're delighted to be an active participant in Australia's wireless future. This is a very technology-focused marketplace with enormous Internet and wireless penetration," said ArrayComm's executive vice president Nitin Shah.

The company said that, unlike cellular voice networks, which are designed for paired spectrum, i-Burst is optimised for unpaired bands.

By using unpaired frequencies, also referred to as time division duplex (TDD) spectrum, the company said the i-Burst system will integrate with its IntelliCell technology, which is used in wideband code-division multiple access (WCDMA) and GSM networks, thereby maximising the spectral efficiency of wireless networks.

The TDD spectrum is ideal for data-only networks such as i-Burst because of its asymmetric transmission characteristics, which mirror those of the wired Internet, company officials said.

The i-Burst system is undergoing technology trials at ArrayComm's US facilities, with a trial set to follow later this year in San Diego.
