Most of the vendors have small cell product line. The real difference lightRadio makes is it so small so can be attached to antenna. On microwave range which used by cell phones radio wave decay very fast in copper line between the radio head and antenna. And bring an optical fiber or ethernet cable to radio head is very easy compare to bring a thick copper cable from radio head to antenna. To get radio head connected next to antenna solved the problem. lightRadio, like LTE, will become an industry standard and other vendors will adopt and catch up, but whoever bought up the concept and first product will command bigger market share, like Ericsson did in LTE. ALU will go to $7 this year once it can show positive cash flow and balance sheet.
