ZTE's LTE BBU+RRU distributed BS solution has the following predominance: 1. Clearer and Simpler Network Instead of running hardware independent platforms for each technology, operators can have various wireless technologies implemented in software on the same hardware platform. 2. Lower TCO (Total Cost of Ownership) Fewer engineers are required since there is a single platform to manage and maintain. The operational expenditures are kept to minimum compared to running several hardware platforms. The TCO for a mobile network is much lower in performing upgrades for the new wireless technology due to multi-technology deployment supported by SDR-platform. 3. Lower Investment Risk Since hardware platforms can be reused, there is significantly less investment risk for deploying hardware. Wireless technologies develop so fast, and investing on one technology only may bring risk to operators. SDR-based solutions will decrease the investment risk since SDR platform can support various technologies. 2-1 SJ-20110921170448-002|2013-09-12(R1.0) ZTE Proprietary and Confidential ZXSDR R8964 User Manual 2.2 RRU Location in LTE Wireless Network ZXSDR R8964 is a compact LTE remote radio frequency unit, which adopts the digital pre-distortion technology, high-efficiency power amplifier technology and SDR technology.
