LG tips 3G phone that transmits images

date: 9th December 2000, source: EE Times

A synchronous version of a new third-generation wireless phone developed by LG Information and Communication can transmit image data at 384 kbits/second.

The mobile phone, which was demonstrated here earlier this month at the Anyang Central Institute, is based on the emerging global International Mobile Telecommunication 2000 (IMT2000) standard. Along with its 384-kbit/s image transmission capability, the phone provided 155-Mbit/s asynchronous transfer mode (ATM) exchanger capability between networks and from central to local offices.

LG said its IMT2000 phone also provides multiplexed voice communications using error-resilient video coding along with ATM switching. Image transmission speed is also enhanced using a multi-carrier technique, which combines three channels of 1.25-MHz unit frequency band and is compatible with IS-95 CDMA systems.

LG said it plans to add features to the high-speed phone after commercialization of IMT2000 systems begins in earnest in 2002. Such features could include international roaming and compatibility with different networks.

LG and other wireless-phone makers are ramping production in anticipation of the launch of competing international standards under the IMT2000 umbrella — synchronous (CDMA-2000) and asynchronous (wide band CDMA). Some observers expect the new wireless spec will embrace both synchronous and asynchronous techniques, rather than rely on single-mode operation.
