Magnolia Broadband Successfully Completes Field Trials of Mobile Transmit Diversity Technology With SK Telecom

Marks Final Field Trial Before Introduction in 2006

SEOUL, SOUTH KOREA and BEDMINSTER, NJ -- (MARKET WIRE) -- July 27, 2005 -- Magnolia Broadband, Inc., (portfolio member of Silverstar Holdings) (NASDAQ: SSTR) a fabless semiconductor company and innovator of antenna diversity radio frequency (RF) solutions for the wireless industry, announced today that they have successfully completed field trials of Magnolia's Mobile Transmit Diversity solution, DiversityPlus™, with SK Telecom (NYSE: SKM), Korea's leading wireless telecommunications services provider. For the first time, the test results showed similar performance gains in commercially designed handsets as previously experienced in test platforms. As seen in this and prior tests conducted by SK Telecom, mobile transmit gains of 4 to 5 dB's have shown to significantly improve capacity, coverage and data throughput in commercial cdma2000 1xEVDO networks. The test also indicates that by deploying Magnolia's technology, network operators can significantly save on capital and operating expenses.

The field testing, which took place the week of July 18th in Seoul, was attended by more than 70 wireless industry leaders including other telecom carriers, handset OEMs, UMTS and WiMax base band chip providers. This test was a major interim milestone to SKT and Magnolia's road of offering handsets in 2006.

The commercial deployment of Magnolia's DiversityPlus chips in dual antenna cell phones will enable wireless carriers to significantly serve more subscribers within the same wireless infrastructure, eliminating the need for additional cell towers, while boosting coverage, data throughput and battery life. Additional benefits for carriers and consumers will be improved quality of service, include more reliable connections, fewer "dead zones," improved quality of service and a substantial lowering in the amount of energy cell phones emit.

"We are very pleased with the results of the field testing with Magnolia's Mobile Transmit Diversity technology and we will continue to work with them closely so that we can realize the significant benefits in our network," said Dr. Myung Sung Lee, Chief Technology Officer and Executive Vice President of SK Telecom.

"The successful results of the tests demonstrate that our innovative diversity technology will be a leading solution for enhancing CDMA-based networks in the Korean and other global marketplaces," said Osmo Hautanen, CEO of Magnolia Broadband. "We are now looking forward to offering our solutions to other protocols such as UMTS and WiMax."

DiversityPlus™ is a family of RF chipset products designed around Magnolia's unique algorithms for CDMA, UMTS and WiMax mobile terminals. By combining transmit and receive RF signals from two antennas in a unique way, the wireless operators increase their network capacity and significantly improve coverage and data rates to the individual subscriber. Simulations have shown that Magnolia expects comparable performance gains in both UMTS and WiMax.
