Capacity Off Load

Mobile network operators are facing skyrocketing demand for voice and data services on their networks. Cisco predicts that "Globally, mobile data traffic will double every year through 2014, increasing 39 times between 2009 and 2014." To meet this demand, mobile operators have responded with costly network build-outs and wide-scale technology upgrades. While these actions can meet some of the projected increases in demand, these carriers have stated that they need access to significantly more spectrum (frequencies) if they are to meet anticipated demand over the next five years.

In the US, the FCC has pledged to make an additional 500 MHz of spectrum available over the next 10 years. However much of this spectrum will be offered on a secondary or unlicensed use basis. The FCC has made it clear that opportunistic use of this spectrum via cognitive radio networks is a key part of their plan to mitigate the looming spectrum crisis.

xG's xMax carrier-class cognitive radio network solution, can add additional capacity to mobile network operators' existing networks while positioning them to take advantage of new unlicensed and opportunistic use spectrum bands in the future.

xMax allows mobile traffic to be shifted off expensive, licensed cellular spectrum and onto unlicensed spectrum today - while offering the reliability, coverage and manageability they demand. xMax offers mobile users a licensed experience using unlicensed spectrum.

xMax can also be used to increase the capacity and utilization of a carrier's existing licensed spectrum. Its patented cognitive radio technology can be applied to licensed frequencies where it can opportunistically put any unused capacity (no matter how brief) to work, without impacting primary wireless services or users. This additional capacity enables the delivery of new revenue-generating services, or could also be used as “overflow” to help relieve pressure on these capacity constrained networks.

Just as mobile carriers found that WiFi (which operates on a different unlicensed band) could be used to reliably offload data traffic on to fixed, local area wireless networks, xMax allow operators to offload both voice and data on to a fully mobile wide area mobile network operating in unlicensed spectrum.

xMax is the only system that is designed to recapture unused capacity on both existing licensed spectrum, as well as unlicensed bands – while still offering carrier-class voice and data services.
