Most low-end cell phone connectivity is infrared technology used in some high-end phone with a Bluetooth data connection and USB2.0 technology, data transmission speed, transmission distance is greatly improved. Bluetooth technology and USB interface in the low-end machine will be further expanded. As cell phones continue to function and performance of the rich and the increase in power consumption, the industry has always been committed to improving the cell phone to be power-up time, improve the methods of phone time to be electric, including a more energy-efficient components, using a higher battery capacity lithium battery, fuel cells, and the use of more advanced power management technology. In early 2006, Motorola and Google have signed a global mobile search partnership agreement to integrate into cell phones in some Google search engine shortcuts, such cell phones sold in the first quarter of 2006. Integrated mobile search function triggered the further development of cell phones. The drawing of关键词is one of the inspection items.
WCDMA and HSDPA touted by the industry, natural supports WCDMA and HSDPA mobile networks will also become a hot spot. In addition, GPS, Wi-Fi, UWB, DVB-H, DMB, and South Korea's Wibro standard mobile broadband communications industry are the focus of attention techniques. Compatible with a variety of network technology has become the development trend of future cell phones. Chip integration process is an important multi-mode cell phone chip security technology, current technology has been integrated chip from the original 0.18-micron, 0.13 micron full access to the 90 nm era. To produce a standard to support more network chips, require a higher level of silicon integration technology. The difficulty lies in the RF chip integrated digital and RF integrated the two parts of the crosstalk problem, the problem to be solved.

Multi-mode technology mainly refers to the down under the same technical system compatibility, such as a cell phone while supporting different frequency bands of the WCDMA / EDGE / GPRS / GSM networks, as well as backward compatible with EV-DO phones such CDMA20001X and CDMA95A. 2006's multi-mode technology, its meaning is more extensive, with a cell phone network in support of the same technical system, based on the system and also supports different types of networks. For example, support both WCDMA / EDGEGPRS / GSM and CDMA20001X/CDMA95A network, or to support a variety of standard cellular network, also supports Wi-Fi networks a variety of VoIP features and standard satellite radio, mobile terrestrial digital broadcasting network and GPS signals and so on. The technicians are discussing the data on the drawing of  china cell phone jammer.
