The five-mode ten-frequency time-sharing long-term evolution plan (TD-LTE) chip war begins. In order to make mobile users unimpeded when roaming internationally, China Mobile has provided TD-LTE supply chain manufacturers with at least five-mode and ten-band product specifications, thus stimulating related chip manufacturers to compete and making multi-mode and multi-band Competition in the TD-LTE chip market is heating up rapidly.
According to analysis, China Mobile is actively developing multi-mode and multi-frequency TD-LTE terminal mobile hotspot (Mobile Hotspot) devices and smart phones, and through the integration of FDD-LTE functions, backward compatibility with 3G and other product strategies to break TD-LTE The use of the device is limited, and then TD-LTE becomes the goal of mainstream LTE networks.
It is understood that China Mobile currently expects supply chain manufacturers from TD-LTE Band 38/39/40, Frequency Division Duplex (FDD) -LTE Band 3/7, Broadband Code Division Multiple Access (WCDMA) Band 1/2/5 , Time-sharing-synchronous code division multiple access (TD-SCDMA) Band 34/39 and Global Mobile Communications System (GSM) Band 2/3/5/8 and other communication modes and frequency bands, at least select the five-mode ten-frequency scheme Integration to strengthen the market competitiveness of China's TD-LTE network.
In fact, China Mobile announced four mobile hotspot devices at the 2013 Global Mobile Communications Conference (MWC), namely Huawei E5375, ZTE MF91S, and China Mobile CM510 and CM512; it also announced four smartphones, including music Golden (LG) OpTImus Vu Plus, HTC TD 101, Huawei Ascend D2, ZTE U9810, etc. are all five-mode ten-band or five-mode twelve-band solutions. It is expected that these products will be launched for China Mobile after the second quarter of 2013 Supply.
According to reports, China Mobile plans to supply TD-LTE mobile phones to friendly users from the first quarter to the second quarter of this year. The estimated number is about 10,000 or 20,000.
As for the competition situation of mobile phone chip vendors in the Chinese TD-LTE market, although Qualcomm has advantages in integrating multi-mode chip technology, and most of China's LTE mobile phones currently use Qualcomm chips, at present, major TDs such as ZTE and Huawei -The LTE mobile phone brand factories all adopt the subsidiaries of Lianxin and Hisilicon products, and MediaTek chips will continue to adopt a low-price strategy to grab the market, making the Chinese TD-LTE chip market fierce.
On the other hand, in addition to the five-mode ten-band is a necessary direction for the development of TD-LTE networks, China Mobile also intends to increase the frequency band to TD-LTE Band 41, FDD-LTE Band 1/17 and GSM Band 5, etc. Two-band TD-LTE network development. However, the five-mode ten-band device is sufficient to meet market demand, and the five-mode twelve-band solution will not only increase the difficulty of chip manufacturers in antenna and radio frequency (RF) design, but also raise the device cost threshold. The five-module ten-band frequency will be the main development direction of the market.
