NEC Corp. has launched the ePASOLINK compact wireless transmission system, which enables mobile network operators to build a cost-effective, IP-based mobile backhaul network that meets the high-capacity data demands of mobile broadband technologies such as HSPA, WiMAX and the anticipated LTE.

"We expect that as mobile operators deploy 4G mobile broadband networks, there will be a step up in capacity demand in the tail links to cell sites and in the aggregation portion of backhaul," said Hiroyasu Ishii, General Manager, Global Network Division, NEC. "NEC continues its close relationship with leading operators across the world and we are confident that ePASOLINK will be a key component of their strategic portfolio to address the need for increased network capacity."

ePASOLINK provides ultra-high link throughputs of up to 2.5 Gbps in the E-band spectrum range of 70/80 GHz. Traditionally, mobile operators have addressed capacity needs with microwave and optical product solutions. However, there is a gap where sub-42 GHz microwave spectrum becomes congested and the fiber optic alternative is too expensive to deploy efficiently. This is particularly the case in dense urban and suburban areas where operators often face intense competition in the expansion of 4G mobile broadband infrastructure.

ePASOLINK provides scalable transport of 2G, 3G, HSPA, WiMAX and LTE, in addition to its support for both Ethernet and SDH/SONET protocols with carrier-grade reliability. The system also helps mobile operators to build and operate their backhaul networks with a low cost of ownership. For example, it is supported by NEC's widely adopted Network Management Systems, which facilitate the easy integration with existing microwave infrastructures, such as PASOLINK.
