Airvana upgrades EV-DO software

Airvana announced an upgrade to the company's radio network control technology to give CDMA 1xEV-DO operators more capacity and higher data speeds. Some 70 operators worldwide use Airvana's technology, including Verizon and Sprint. Airvana's upgrade enables CDMA operators to increase the number of sites it can fit in a cluster.

"With Airvana's RNC clustering, operators can deploy multiple RNCs without introducing any RNC borders that can cause service interruptions as subscribers cross them," the company said. "This benefit is especially important for delay-sensitive applications such as push-to-talk and push-to-video."
