HONG KONG-Several infrastructure vendors reported successful demonstrations at the 2005 3G World Congress and Exhibition in Hong Kong.
Motorola Inc. unveiled a prototype CDMA2000 1x EV-DO Revision A solution, which enables operators to offer enhanced services such as simultaneous video, voice and data applications.
“Motorola’s all-IP CDMA architecture is ready to support Rev. A, and our integrated radio access network solution lets operators leverage their existing investment as they make the migration to this new technology,” said Bruce Stone, senior vice president of Cellular Networks at Motorola.
Motorola said the prototype demonstrated downlink speeds of up to 3.1 megabits per second and uplink speeds of up to 1.8 megabits per second during live Voice over Internet Protocol and video telephony calls.
The company explained that the Rev. A standard is an enhancement to the EV-DO Rev. 0 standard and combines voice and data on a single carrier. The technology eliminates the need for separate networks for circuit voice and packet data. Motorola said its product increases voice capacity and also allows multiple concurrent data links.
Motorola said its Rev. A solution should be ready for deployment in 2006, and noted that its EV-DO Rev. 0 system can be migrated to Rev. A with hardware and software upgrades.
Motorola also launched its ColorNotes solution for CDMA and GSM networks, which converts traditional voice or short messages to multimedia messages that incorporate animated graphics and audio. Motorola said ColorNotes enables users to send messages containing animated characters and allows consumers to choose which “emotions” the character will have while portraying their message. The applications also enables users to receive broadcast messages, such as news clips, stock quotes, horoscopes and jokes delivered by animated characters.
Zhejiang Mobile Communications Co., a subsidiary of China Mobile, is deploying the service.
Separately, Siemens AG said it planned to demonstrate its new nanoEDGE base stations, which the company said provides full EDGE wireless coverage inside buildings.
“EDGE enables our customers to further broaden their data-intensive services and generate new revenues through higher data traffic,” said Christoph Caselitz, president of Mobile Networks at Siemens.
Finally, Lucent Technologies Inc. said it showcased its “blended lifestyle” solutions that the company says combine voice, data and video services using third-generation and IP Multimedia Subsystem technology.
The company said it was also conducting over-the-air demonstrations of EV-DO Rev. A and HSDPA technology.
Lucent pointed out that HSDPA technology enables W-CDMA/UMTS operators to introduce high-speed data services such as DVD-quality streaming video and faster downloads of large files, as well as virtual private network access to corporate networks.
