A few days ago, China's 3G technical test at the industry, the second phase of the external field test was completed as scheduled, and the test results were positive. Test shows that the current 3G technology has been basically mature, and the type of 3G terminal is also relatively abundant, which has a considerable progress than the conclusion after the first phase of the test.
According to reports, 3G technical test is divided into two phases, especially in the second phase of the second phase of the second phase. The main test contents of this phase include: Wi-Fi network performance testing, terminal testing, business testing, interoperability testing, network management and billing, and wireless interference.
The test results show that the overall function of the WCDMA system is relatively complete and stable; most terminal is perfect, the stability is better, the level of maturity and compatibility of the minority terminals are slightly poor; the system and system, the system and the terminal, the terminal and the business platform Compatibility is better; interoperability issues in video services such as visual calls have been greatly improved during the test; the wireless performance indicators such as capacity and coverage are better.
The overall test of CDMA2000 1X and HRPD technology is better; CDMA1x and HRPD system functions are perfect; the system and terminal compatibility are good; wireless network performance indicators are good. However, the 3G expert group also pointed out that due to the test of the core band, the number of terminals that participated in the test was limited, and the business supported by the terminal was limited.
TD-SCDMA technical test results show that the current device has a basic function, but the test has only completed partial performance testing. TD-SCDMA manufacturers participating in the test have only three, Datang, Putian, and ZTE's product research and development speed have increased significantly. These three companies jointly provided a full set of wireless network equipment, Datang also provided testing phones.
According to reports, the 3G technical test organized by the Ministry of Information Industry begins in June 2001. 3G technical tests were in May 2002, respectively, in August 2003, the first phase of the first test and second test were completed. This completed the most important second phase test. It is reported that the six major operators, 12 system equipment and ten terminal manufacturers are actively involved in this test, and three UIM card manufacturers have also participated in the test.
