TD-SCDMA Terminal Evaluation and Development Strategy (1)

Status Quo of TD-SCDMA terminal industry chain

1. TD-SCDMA Chip

TD-SCDMA terminal industry chain includes Baseband Chip, RF chip, testing instruments, software development and application platform development and many other links. In general, the current terminal industry chain is relatively well developed. In terms of terminal chips, the chip products have been successfully launched by Zhan Xun, T3G, Lianxin technology, huali, and chongyou. All chips have achieved TD-SCDMA voice, short message, 128 kbit/s data business and a variety of switching functions, including TD-SCDMA/GSM dual-mode switching. Some enterprises have achieved 384 kbit/s high-speed data services. At present, the above manufacturers have launched available for commercial TD-SCDMA terminal chip products.

With the support of chip enterprises, Datang, Lenovo, xiaxin, Hisense, Samsung, LG and other terminal enterprises have developed more than 40 TD-SCDMA terminals. The product features, exterior design, lightness, diversity and power consumption indicators have all reached a mature level. TD-SCDMA terminal products have been able to provide including basic voice, visual phone, Web browsing, video on demand and other typical 3G business, terminal products have a major breakthrough in the standby time.

The chip series of various manufacturers and the commercial release time are shown in table 1.

2. Development Platform of TD-SCDMA Terminal

TD-SCDMA terminal intelligent operating system mainly includes Linux, WinMobile. Currently, the Symbian-based smart TD-SCDMA terminal program has not been seen.

3. testing instruments and meters

At present, there are a total of 8 TD-SCDMA terminal testing instrument manufacturers on the market, of which there are 6 terminal comprehensive tester manufacturers, respectively, the domestic Hubei Zhongyou, Galaxy highlights, 41st CLP Technology Group, foreign companies such as wiltek, anli, and Yoko. Anjet and rode and Schwarz have only terminal test instruments in non-signaling mode.
