China Mobile, Huawei and Qualcomm Technologies said they completed the commercial verification of TDD+ uplink data compression technology on a commercial LTE-TDD network.

UDC is claimed to enable operators to maximize LTE-TDD uplink resources, increasing the number of uplink users and achieve compression efficiency for various applications such as messaging services and Web browsing.

Huawei said that the deployment of UDC does not require any hardware upgrade. On the network side, operators need only upgrade Huawei's ENodeB software. On the terminal side, the technology is fully implemented in the LTE modem and thus completely independent from the mobile phone's operating system.

Last month, the Chinese vendor launched its new TDD+ solution in collaboration with its industry partners China Mobile and Japanese telecom operator SoftBank. The solution is set to be commercially available next year.

Huawei said that the TDD+ technology can provide a multi-gigabit-per-second-level user experience, uncover more business opportunities for carriers and maximize their return on investment. TDD+ is also designed to increase spectral efficiency and system capacity by using high-performance cloud-baseband chips and features such as distributed multiple input/multiple output, massive carrier aggregation, high-order modulation, high-order MIMO and multiuser 3D beamforming.

In related news, China Mobile rolled out its voice-over LTE voice services in Zhejiang, the first province in China to enter into the VoLTE era. The rollout was carried out in partnership with Huawei, which recently won nearly half of China Mobile's nationwide VoLTE project. The provinces involved in Huawei's contract are Beijing, Shanghai, Tianjin, Guangdong, Zhejiang, Jiangsu, Fujian, Hunan, Guizhou, Shanxi, Guangxi, Jiangxi, Heilongjiang, Hubei, Anhui and Jilin.

China Mobile aims to provide services for 50 million commercial VoLTE subscribers by the end of 2015 or the beginning of 2016.

China Telecom ends first half of 2015 with 320,000 LTE base stations

China Telecom invested a total of 17.8 billion yuan ($2.8 billion) in its LTE network in the first half of 2015. The operator ended June with 320,000 LTE base stations across the country, and aims to reach 510,000 LTE base stations by the end of 2015.

By the end of the first half of the year, China Telecom had 29 million 4G terminal users, compared to 7 million at the end of last year.

The telco recorded revenue of 164.9 billion yuan in Q1 2015, down 0.6% vs. the year-ago period. The company's net profits for the period totaled 10.9 billion yuan, down 4% year-on-year.

China Telecom is looking to provide LTE coverage to 95% of the country's population by the end of the year, according to previous press reports.

The country's No. 3 mobile company with approximately 192 million subscribers, China Telecom obtained its nationwide FDD-LTE license in February, having previously launched 4G services through a hybrid TDD/FDD network.

Feb.16,2011, China Telecom announced its "Broadband China, Optical network City" strategy this afternoon in Beijing. Including Mr. Wang,xiaochu, CEO of China Telecom, nearly the total managing team of the carrier appeared on the news conference. The company announced that they will increase FTTH subscribers by 30million in 2011, 3 times as all subscribers obtains in the past 5 years, and they will build fiber access network in all cities of mainland China in 3 years.

Mr. Sun,Junyan, general manager of network development department of China Telecom told the media that the bandwidth of their backbone internet doubles every 17 months. In past 5 years, China Telecom has invested nearly 150billion Yuan on broadband network. In the future 5 years, China Telecom aims to increase 20M bandwidth network cover rate to more than 80% in all major cities of mainland China, to reach 100% FTTH cover rate in all cities of southern China, over 100 million home has 100Mbps bandwidth cover. At the same time, China Telecom will reduce their price per bandwidth greatly in 3 years. Besides the broadband network developing, China Telecom will also build their M2M and cloud platform to provide more new applications to customers in the future.

On the other hand, Wang,xiaochu talked more about China Telecom's current broadband network. According to him, China Telecom now has more than 110 million broadband terminals, including 20million PON terminals, more than 70 million broadband customers. Total bandwidth of China Telecom's backbone Internet ChinaNET reaches 20T, international bandwidth reaches 440G. With the rolling out of China Telecom's "Optical fiber replacing copper" strategy, in major southern cities, 20M bandwidth cover rate has increased from 10% to 58%; 4M bandwidth cover rate has increased from 53% to 98%; FTTH network has covered 10 million homes; Fiber has been connected to all commercial buildings; 70% villages in southern China has been connected with fiber.

For the first time, China Telecom puts FTTH on a very high position. In Sun,Junyan's speech, He mentioned that ultra broadband network has been raised to national strategic level by many European, North American and Asian Pacific countries. All those countries have made hugh investments on broadband network constructing. China's most recent 12th five year plan also required to put information industry on a very high position. However, compared to those advanced nations, China's broadband network still has many problems. By the end of year 2010, only 23% Chinese families have broadband connection.

China Telecom also predicated that their new FTTH strategy will bring tens of billion Yuan business opportunities for fiber optics industry. This huge business opportunity will be a big boost for China's telecom industry. At the same time, the rolling our of this strategy also puts huge request on engineers in the fields of optical network building, maintaining and marketing. This is also a big boost to the whole society.
