According to the news on November 3, people familiar with the matter revealed that China Unicom and China Telecom also participated in the test of China Mobile's TD-LTE technology scale, which was the focus of attention. , But they are all Internet cards, and mobile phones have not yet entered the field, they will be used in the next stage of testing. In the early stage of the technology scale test, the Telecommunication Research Institute of the Ministry of Industry and Information Technology established two laboratories in Shunyi, Huairou, Beijing. Each manufacturer has a test environment of 15 cells, thus forming 11 systems and more than 80 base stations.
Later in 6 cities, there were 1-2 system equipment manufacturers in each city, and each manufacturer had 110 base stations. The main coverage areas are outdoor scenes such as urban commercial areas, residential areas, urban arterial roads, streets, and some hot spots. Regional and indoor scenes.
It is reported that although this test is dominated by the Ministry of Industry and Information Technology and China Mobile, it is reported that in the test group, the three major operators of China Mobile, China Telecom, and China Unicom have participated, plus the Ministry of Industry and Telecommunications Research Institute to form the test group.
Over the past two years, more than 3,500 people have participated in the test, and a total of more than 20,000 test case combinations have been completed.
So far, 7 system equipment manufacturers and 3 chip manufacturers have completed the first phase of the test, but including wireless network performance, multi-chip test, indoor coverage, terminal test, and core network and bearer test . There are also three that have either not entered the field or have not completed the test. But even so, according to the original plan, the first phase of the test has come to an end, and it is still in the evaluation phase.
Regarding the terminals, it is reported that China Mobile has purchased more than 2,000 terminals for this scale test, but these terminals are all network cards and are relatively simple single-mode chips. In fact, existing manufacturers have developed LTE / TD dual-mode chips, but have not yet entered the field test.
The LED exit sign light is specially made from aluminum and acrylic materials, and is also fast dissipating heat, insulating and corrosion resistant. LED emergency lights are illuminated with super bright LEDs to ensure visibility in dark corridors and hallways. In case of an emergency power outage, the exit lane will be illuminated. Exit signs are designed for various types of indoor commercial uses such as hotels, shopping centers, theaters, restaurants and other public places. Any emergency exit signs must have continued reliability. Easy to install and can be hung on the wall or from the ceiling.
