Sumitomo Electric Industries Ltd. announced the introduction of the TRU2640, its advanced remote radio head (RRH) designed for use in Time Division-Long Term Evolution (TD-LTE) networks. Telecommunications operators are increasingly required to expand their coverage and capacity to meet customer needs. For these operators, it is vital to deliver strong signals to a large given area, and thus, many operators deploy RRHs in their base stations. As the base stations increase in number, any OPEX and CAPEX savings for a base station create considerable difference in their bottom line. The TRU2640 has a high power efficiency of 20%, weighs less than 15 kg, and operates in the 2.6 GHz band, the most commonly used band for TD-LTE systems. Requiring smaller backup power systems, the TRU2640 saves on monthly electric costs and simplifies inventory, resulting in the reduction of their CAPEX. This high power efficiency, coupled with technology developed by Sumitomo Electric, enables the TRU2640 to be the most environmental-friendly RRH in the market, while maintaining the installation flexibility and performance. Available in 2x2, 2x4, 4x4 and 4x2 configurations, the TRU2640 meets and exceeds all specification requirements contained in the 3GPP standards. The TRU2640 also offers optional support for multi-carrier operation, which enables operators to expand capacity in the future without truck rolls or tower climbs. Supporting a standard Common Public Radio Interface (CPRI), this RRH offers a blend of standards implementation and performance.
