On July 13th, when I went to Guangzhou to experience the TD-LTE network, I learned that the TD-LTE data card can be actually used. This ZTE (Weibo) TD-LTE Internet card claims to support TD-LTE at the same time / TD-SCDMA / FDD LTE / EDGE four standards, and supports 11 frequency bands.
Previously, TD-LTE terminals had data cards, mobile phones, tablet computers, etc., but they were basically single-mode terminals. However, it is generally believed that TD-LTE must be a multimode terminal if it is to be commercially available.
Guangdong Mobile (Weibo) is the pioneer of China Mobile (Weibo) TD-LTE. It has conducted TD-LTE technology scale trials in Shenzhen and Guangzhou. Among them, it was installed on the bus of Guangzhou University City in May this year. The CPE wireless gateway device can convert the TD-LTE network into a WiFi signal. The highest test rate is 112.02Mbps, but there was no external test of the TD-LTE network card.
In an office located on the sixth floor of Guangzhou Mobile, Sina Technology has finally seen a TD-LTE multi-mode terminal. This is a TD-LTE Internet card provided by ZTE, which is 1/100 larger than the current TD-SCDMA. 3. The whole body is black. Guangzhou mobile technician explained that this is only the network card used in the test. It will definitely be smaller in real commercial use. Currently, only the ZTE TD-LTE network card is used in Guangzhou, but as long as the chip is mature, this This terminal will develop quickly.
It is reported that this is the world's first TD-LTE / TD-SCDMA / FDD LTE / EDGE multi-mode single-chip data card, which supports multi-mode 11 frequency bands, allowing users to operate smoothly in most system environments. Up to 100 / 50Mbps.
At present, there are more than ten TD-LTE chip manufacturers. However, compared with the foreign commercial LTE market, a leader of the Telecommunication Research Institute of the Ministry of Industry and Information Technology also recently said, "TD-LTE terminal chips are still a weak link in multi-mode, process, and stability. , Power consumption, cost, etc., there is still a gap, need to quickly increase the whip, only fight for the day. "
