Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
Korean electronics giant LG Electronics has developed what the company claims is the first 4G handset modem chip based on 3GPP Long Term Evolution (LTE) technology standards. The chip can theoretically support wireless download speeds of 100Mbps and upload speeds of 50Mbps.
The fastest mobile phones currently on the
market use High-Speed Downlink Packet Access (HSDPA) technology and
download at a theoretical maximum speed of 14.4Mbps. Ericsson recently
announced an upgrade to Telstra's Next G HSPA (High Speed Packet
Access) mobile data network to 21Mbps. HSPA+ has a theoretical limit of
42Mbps.
LTE technology is a leading candidate to become the fourth generation mobile phone technology standard.
The modem chip is the most crucial component required to create a viable 4G handset.
LG demonstrated the chip today at its Mobile Communication Technology
Research Lab in Anyang, Korea, achieving wireless download speeds of 60
Mbps and upload speeds of 20 Mbps.
Higher download speeds are becoming more and more important as people
are increasingly using their mobile phones to watch movies, listen to
music and browse the internet. With LTE technology, users could
theoretically 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, according
to LG.
The LG chip is 13mm by 13 mm modem chip and is designed to be used with
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 a 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% 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 LG.
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.
Dr. Paik added, "Our successful development of this LTE handset modem
signals the start of the 4G mobile communications market. LG will
continue to advance this technology and develop further technologies to
maintain global leadership."
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.
