Editor's Notes
- 我会诚恳的回答你们的问题
- There are four parts about today presentation. In The frist part ,i will give analysis of the requriement of the opeartors for green mobile nerwork Introduce In the next,i want tell three 绿色技术的运用 At last give a conclusion about today presention 。 Start to the frist part
- Let us analyse this question from another standpoints ，这边是关于 TCO 的分析，移动运营商门对着越来越 intense 的 competition ， TCO is made up of capex and opex, let us analyse the capex fristly ,the expense of buy nodeB is just 22% of whole capex, however ,other expense such as equipment room ,tower are almost 80%. So we want to the ratio of main equipment is about 27 percent , network construction such as equipment and Tower is about 24 percent altogether How to reduce the tco ,we should analysis We need Power generator and power backup is 50 percent. Let us look opex example is the largest part of opex,about 38 percent, Capital expense operating expense
- It is our company understanding about 绿色移动网络 但是怎样建设一个绿色移动网络呢，中兴 umts 绿色解决方案将会给从四个方面给出答案 from 4 aspects
- 降低网络能耗最有效的方法是减少基站数量， UMTS 系列基站通过下面的方案能够有效增加基站覆盖范围，进而减少建站数量和降低能耗 The best way to reduce the cost of network is decrease sites number, zte umts nodeb could improve the coverage and reduce the number of sites with these techonologies,how to reduce sites number, if there is no limit about cell capacity, we can reduce the sites number through improve coverage of the cell, 减少站点数量：既可以又可以 multi-antenna receive , 下行容量不受限 TMA (Tower Mounted Amplifier) With special algorithm ,our company realize the efficiency of pa is up to 40 percent ,and in the future ,we will provide higher efficiency PA The table below gives us two numbers, the most efficient method to reduce the node B power cost. Zte company has a good team to develop the high efficiency PA techonolgy digital pre distortion

- According to our statistics , average radio resource usage is only 6.06%, 29.4% and 42.4% in the period of low, middle and high traffic. The status transfer from high traffic to medium traffic, period in the large quantity base station, the power consumption straightly influence profit of operator. In the past time, base station will be working all the day. No matter it is low traffic ,medium traffic or high traffic. The cost of the power is wasted meaningless. In the case, it is necessary to adopt some special technology to shutdown partially power during low traffic period.. Transceivers modules in BTS can be switched off automatically depending on the traffic load. threshold For the same reason Figure out
- The share of
- 无线网络占总能耗的比重最高，其能耗构成中基站主设备的能耗最大，占整个机房能耗的 51% ，机房空调能耗占 46% ，其他配套能耗 3% 。由此可以看出，机房空调的节能也相当重要。 风扇的转速跟室内和室外的温差相关，温差越大，则风扇的转速越快，温差越小，则风扇转速越慢。在这种情况下可以不使用空调。机房里的设备需要 Appropriate temperature for stable working equipment The temperature monitor detect the outdoor temperature satisfy…. The misu give the instruction to air exchange system during Almost 70% of time, of annually can adopting nature air substitute air-condition. temperate regions
- Infrastructure construction not only cost a lot of money ,human resource but cost a lot of resource 如果运营商拥有 GSM 网络，这是不可多得的宝贵资源，能否充分利用 GSM 网络资源是优质、快速、低成本建设 UMTS 网络的关键。 在采用传统基站产品的情况下， 2/3G 共站建设方案如图所示： 1. 看看现有站点的资源有无富裕，机房空间、电源、传输啊等等； 2. 如果运气好，条件都合适，那就再塞一个 NODEB 进去 这种方式也可称为 passive sharing ，主要是共享基建和站点的配套资源，如图上所示：方舱、电池、电源、空调、铁塔、传输等。 如果是基于 SDR 的方案，则可以共享的更彻底，效率更高，投入更低，请看下页！
- [Presentation Key Points]: Infrastructure cost occupy high percentage of the TCO, especially the equipment room construct/rent cost. Distributed Node B is introduced to solve this problem The idea is that we divide the traditional Node B to be two parts, the baseband part to be the BBU (Baseband Unit), and the radio frequency part become the RRU (Radio Remote Unit). BBU is deployed in the centralized manner, and connect RRU with fiber. The maximum distance can be 40km. RRU is deployed close to the antenna, the feeder loss is decreased, coverage get expanded; The distributed Node B can be applied in many scenarios: large scale BBU +RRU, extra baseband resource of Macro Node B (Micro Node B)+RRU, or BBU+RRU for indoor coverage. Both BBU and RRU are very small in dimension, support convenient/flexible installation. BBUB is only 3U height, support flexible installation; Can be installed on the wall, in transmission rack, 2G/3G BTS rack, or even in the light current well or basement of the building. ZTE RRU can be mounted on the pole/pillar, wall and the top of the tower, etc. In this way save the equipment room space, speed up the network construction, decrease the maintenance cost. Save the TCO for operators; [Remarks]: BBUB: ZTE BBUB is designed with high capacity, 4 BP boards with full configuration (maximum 768 CE) per BBUB, 12 cells are supported; GSM/WCDMA dual-mode; Support two shelf cascade, baseband smooth expansion; Rich interface, support IP UTRAN; Support HSPA, software upgrade to HSPA+. HW BBU single shelf capacity: 192 CE only per BBU 2 BBU cascade: 6 cells are supported; 2 set of power supply needed RRU: ZTE RRU only 19L in volume, 16.5kg in weight, easily portable and can be mounted on the pole, wall and the top of the tower, etc. The dimension is the smallest one in the macro RRU in the industry, while other vendors’ more than 20 liters; With HPA, lower RRU power assumption; Flexible output power: 20W/40W/60W; Support 1-Carrier to 4-Carrier upgrade, completely adapt to the future expansion.
- For a long time ,zte research the green energy to take place traditional power supply for reducing the emission of carbon Dioxide,and protecting environment . In this picture, I want to introduce three solutions about green energy. Solar, wind energy, and hybrid energy solution. ZTE provides solar power supply system in many countries Wind energy advantage is listed here, Wind energy can provide 24 hours power supply if there is enough wind ,it is a advantage the solar does not have Generally speaking , Seaside, island, plateau, plain are the ideal areas for the wind energy However, the solar and wind energy both have a disadvantage that can provide enough power steadily if the resource of solar or the wind is not enough for a long time .So, in the practical application ,the hybrid energy solution is always adopted. It is structure of hybrid solution ,controller Charge the battery In china ,there is a example ,a base station use these solution ,it have worked steadily for one years,and it just use tow bottles of nature gas.

- ZTE Assist Green Olympics 在奥运举办城市，减少能源消耗和二氧化碳排放是绿色奥运的基本要求。另外，很多运营商因为现有站址没有足够的空间安装大型机柜 ，但为了保障奥运通信，不得不另觅站址，额外支付了新建或租用成本，所以空间资源和机房资源显得尤为宝贵 香港 CSL 项目节能案例 Energy Efficiency Scheme in HONGKONG CLS Project 客户拥有多频段网络在运行过程中有诸多困难和问题，一方面网络基础设施资源浪费严重，大量基础设施无法共享，导致网络操作复杂、网络覆盖和性能优化难度大，维护成本高、特别是机房和电源的支出较大。另一方面现有网络各自独立升级维护以及扩容困难，不支持平滑演进以及与其他网络的融合等问题 每年大约可以省 2300 万度电，相当于减 8000 吨标准煤的消耗，可减少二氧化碳排放量 2.4 万吨。这一数字相当于多达 8000 辆汽油动力汽车的年度排放量（ 3 吨 / 年） 阿富汗太阳能使用案例 Solar Utilization in Afghanistan 由于供电不足，大多数站都是使用双油机工作，不仅维护麻烦（每个 BTS 站点油机维护外包费一年就 4300 多美圆）、耗油（一个站点一年一般在 2 万多美圆），因油机停机还导致网络中断（每天都有因油机故障导致掉站），因道路很差和安全局势问题，要去处理很困难 ，所以客户希望用太阳能替换油机，节省运营费用
- 让我们对今天的宣讲做个总结，作为全球优秀的无线设备供应商，中兴通讯从人与自然和谐共存的理念出发，长期以来致力于绿色环保的通讯技术，在 WCDMA 领域中的 SDR 、高效率功放、 RRU+BBU 、基站小型化等技术处于领先地位，这些技术使得基站的能耗和占地与传统基站相比有了大幅下降，节能接近 50% be adopted in the commercial market.
