Ridin' Millimeter Waves to 4G

5:20 PM -- Clearwire LLC (Nasdaq: CLWR) isn't the only company making waves lately in microwave backhaul. (See Clearwire Gets a New Backhaul Buddy .)

News that the WiMax operator has been using millimeter-wave radios from startup E-Band Communications Corp. as part of its microwave backhaul strategy is the latest in some recent activity in this wireless backhaul area, which promises higher capacity and lower costs for WiMax and Long Term Evolution (LTE) backhaul.

  • NEC Corp. (Tokyo: 6701) recently waded in to the millimeter wave with the introduction of the ePasolink product, which was developed with a partner that NEC said it could not name. The Japanese vendor says that it expects demand for the new product to come mostly from Europe and North America. (See NEC Launches ePASOLINK for LTE.)

  • Wireless backhaul silicon provider Provigent Inc. says it will develop a system on a chip (SoC) for millimeter-wave products in partnership with BridgeWave Communications through a strategic relationship that will effectively see the millimeter-wave vendor become Provigent's first customer. (See Provigent, BridgeWave Team Up.)

    According to Provigent's chief marketing officer Aviv Ronai, LTE is the "Holy Grail" for microwave vendors. "Cell sites will be smaller, closer, and have higher capacity," he says.
