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.

End of Steps 5.3 Replacing Optical Fiber Prerequisite l Perform fault observation and analysis to confirm that the optical fiber should be replaced. l Select the optical fiber with the proper length, and check whether the type of the new optical fiber is the same as that of the old optical fiber to be replaced. l Record the connection position of the optical fiber to be replaced, the new optical fiber should be connected at the original position. l Prepare the moisture-proof bag and certain labels for marking. Context When replacing an optical fiber, pay attention to the following:
l During operations, do not damage the optical fiber cladding. l Protect optical fiber connectors to avoid contaminating them. l Do not forcibly pull out the original optical fiber or forcibly bundle the new optical fiber. 5-2 SJ-20110921170448-002|2013-09-12(R1.0) ZTE Proprietary and Confidential Chapter 5 Product Maintenance l Bend the new optical fiber at the turning. Steps 1. After the old optical fiber is removed, put the protective cap on the optical port so as to avoid contaminating the optical port. 2. Cut off the cable tie of the old optical fiber, remove the old optical fiber, and then put the fiber to the moisture-proof bag. 3. Lay the new optical fiber the same path with the old one, fasten fiber connector, and then attach label on the new optical fiber. 4. Bundle the new optical fiber. End of Steps 5.4 Replacing Antenna Feeder Jumper Prerequisite Prepare new feeder cable the same length and type as the one to be replaced. Context The jumper of the antenna feeder is used to induct the RF signal to RRU and connect the feeder cable of the antenna feeder system. Steps 1. Switch off power supply. 2. Dismantle the older jumper to be replaced. 3. Connect one end of the feeder jumper to the feeder system, and then connect the other end of the feeder jumper to antenna port of RRU. 4. Switch on power supply. End of Steps SJ-20110921170448-002|2013-09-12(R1.0) ZTE Proprietary and Confidential 5-3 ZXSDR R8964 User Manual This page intentionally left blank.
