InterDigital Communications Corporation is making strides in the high-speed downlink packet access (HSDPA) sector, with the introduction of its latest HSDPA coprocessor terminal unit ASIC.

The unit, which is verified in application specific integrated circuit (ASIC) form, supports UMTS Release 5, offers low power consumption, supports transmit and receive diversity and contains architecture making it scalable to Release 6 HSDPA (high speed uplink packet access), according to the company.

The design, according to InterDigital, allows for customized OEM implementation, including integration with existing UMTS Release 99 and Release 4.

"Our mature, scalable HSDPA solution complements our UMTS Release 99/Release 5 protocol software solution and provides a migration path to HSUPA," said Mark Lemmo, senior business development and product management officer, in a prepared statement.

Philips Semiconductor is InterDigital's first HSDPA customer.

InterDigital recently increased its revenue guidance for the third quarter. The company now expects revenue related to patent license royalties and technology solution sales to come in between 447.5 million and $59.5 million. In August, InterDigital estimated third-quarter 2005 revenue from licensees and technology agreements would be in the $34.5 million to $36 million range.

While InterDigital signed up new licensees last month, the company also is involved in patent battles with Nokia and Lucent Technologies. The company is fighting with Nokia over royalties for its 2.5G and 3G technologies and its subsidiary Tantivy Communications has patent litigation pending with Lucent.
