LG Reveals First LTE Chip

LG has announced that it has independently developed the first handset (user equipment) modem chip based on 3GPP Long Term Evolution (LTE) technology standards. The modem chip can theoretically support wireless download speeds of 100Mbps (megabits per second) and upload speeds of 50Mbps. This represents a significant step toward creating a market-ready 4G phone.



LG demonstrated the chip at its Mobile Communication Technology Research Lab in Anyang, Korea, achieving wireless download speeds of 60 Mbps and upload speeds of 20 Mbps. The fastest phones currently on the market use HSDPA technology and download at a maximum speed of 7.6 Mbps.

With LTE technology, users can download a 700 MB movie file in less than one minute at speeds of 100 Mbps. LTE technology would also allow consumers to simultaneously stream four HD movies without any buffering.

For the past three years, LG has been pursuing 3GPP LTE standardization, working to develop and test commercially viable LTE technology with an R&D staff of approximately 250. The result is a 13mm by 13mm modem chip for the next generation of slim handsets. For its demonstration, LG used a test terminal running Windows Mobile to play back high quality, on-demand video. In addition to this handset modem, LG is also developing the first preliminary LTE-based data card, which can replace the wireless cards currently used in computers.

“Now that LG has developed and tested the first 4G handset modem, a commercially viable LTE handset is on the horizon,” said Dr. Woo Hyun Paik, CTO of LG Electronics. “This latest breakthrough gives us a strong technology advantage that we will use to bolster our industry leadership.”

Most of the major mobile operators are pursuing LTE-based 4G technology. Because it is based on the existing WCDMA technology evolutionary path, 85 percent of WCDMA service-provided carriers will be able to upgrade their networks to LTE with far less cost than building a new network based on a different technology.

According to market research company Strategy Analytics, the global LTE handset market will double from 70 million sales units in 2012 to 150 million sales units by 2013. Mobile phone carriers have now built LTE test networks and are currently working on early stage handsets. The first LTE mobile phones will likely reach the market in 2010.
