CMHK Partners with ZTE for LTE Microwave Backhaul Deployment

本帖最後由 u23dom 於 2013-6-6 21:28 編輯

China Mobile Hong Kong(CMHK), a wholly-owned subsidiary of China Mobile,was established in 1997. CMHK was the first PCS (GSM 1800) operator to launch mobile services in Hong Kong, which is one of the biggest economies in the world. The high-rise buildings and dense commercial districts are signs of the city's prosperity, but they also give rise to a complicated radio environment and are a challenge for mobile network construction. Through the use of cutting-edge GPRS, EDGE, 3G HSPA, and 4G technologies, CMHK has been providing customers with professional, innovative communication services. CMHK is now one of the largest mobile broadband operators in Hong Kong and has the greatest potential. CMHK operated a Hong Kong-wide GSM 1800 network to provide GSM voice and data to mainland customers roaming to Hong Kong. Previously, CMHK's lack of 3G networks meant it lagged behind other mainstream operators in Hong Kong. Therefore, CMHK made 4G network construction its key strategic goal. CMHK bought an FDD 2.6G license at auction in 2009 and launched a commercial FDD LTE network in early 2012. It also bought a TDD 2.3G licenseat a high price and launched a commercial TDD LTE network at the end of 2012. LTE networks are being rapidly deployed. Mobile backhauls need to have large capacity and wide coverage because fiber is limited and site rental fees are high. ZTE has rich experience in network construction, project management, and managed services in Hong Kong. Guided by a customer service philosophy, ZTE provided CMHK with a highly reliable,expansible microwave transmission solution that provided high coverage even with limited fiber resources.

CMHK had never used microwave in its network before. ZTE took into consideration transmission cost at end sites when proposing the microwave solution to CMHK and also drew on the experience of deploying microwave in CSL's mobile network. In the CMHK  project, microwaves were used to equipment NR8250 operated smoothly with existing FDD-LTE equipment by Ericsson. NR8250 also out performed other microwave products from Ericsson,Alcatel-Lucent, and Comba in the subsequent QoS and link stability tests. As a result, ZTE was shortlisted as a candidate partner for CMHK. ZTE took into consideration CMHK's existing network conditions and future evolution needs and adopted a highly customized all-IP microwave backhaul solution. NR8250 was used to provide high data throughput and low latency. It supported dynamic allocation between emulated TDM and Ethernet services without any bandwidth loss. This helped CMHK solve the issue of 2G, 3G, and LTE coexistence and pave the way for smooth transition to future IP services. NR8250 has integrated module slots for flexible network upgrade and also provides enhanced Ethernet performance for high link reliability and stability. By the end of 2012, ZTE had delivered and commercialized the first phase of the microwave project. According to the deployment plan agreed upon by both ZTE and CMHK, ZTE will complete the deployment of all microwave sites by the end of 2014. CMHK was responsible for the project execution. ZTE provided technical support in the early stages of professional network planning to assist CMHK getlink certificated by OFCA. ZTE also developed a one-click deployment tool for efficient installation. This tool provides offline parameter configuration that lowers the skill required of the on-site deployer. It also increases the success rate of one-time site deployment and greatly reduces costs for CMHK. In the customer satisfaction survey conducted by ZTE at the beginning of 2013, CMHK praised ZTE's microwave equipment and expressed their expectation for further cooperation with ZTE. “The partnership with ZTE is most important for successful project implementation. We expect further cooperation with ZTE to expand and share the microwave backhaul network,” said Feng Yaojin, microwave project director of CMHK.

問題精結在於CSL/CMHK/SMT無自建光纖網絡,以CMHK有強大水源在背後支持著也敵不過成本的拖累. 若SMT不自建光纖網;遲早也會因成本問題而轉用微波.

何苦呢, 行td-cdma已經係錯, 用microwave仲雪上加霜

都唔一定係壞事,減省嘅成本可用於網絡建設上。

你說笑嗎?   
呢D係擋企惡習
黎香港做生意, 一分一毛投資同花費都只肯用番係大陸既擋企同自己友勾結。
一滴水都唔比香港人賺, 一條毛都唔肯投資係香港。
垃圾移不動, 個2G網係華潤人仔台時期投資起架。 垃圾擋企入主後投資絛毛訝?

仲有
你標題的CXL
係中資操縱
所以又係只可投資比擋企

不要為反共而盲目反倒一切,CMHK在投資頻譜上絕無手軟,閣下論調真的可笑!

莫非FD-LTE & TD-LTE建設不用付出分毫是偷回來? FD-LTE用的是愛立信設備; 莫非愛立信又是國企?

看來閣下不只心盲連雙眼也盲了
