10. New Investors: ST via VT Engineering (US) IDirect Agrees to Sell Itself for $165 Million By Ellen McCarthy iDirect Technologies Inc., a Herndon firm that sells network equipment to satellite companies, agreed to be acquired yesterday by Singapore Technologies Engineering Ltd. for $165 million in cash. The acquisition is the second big deal this week in the consolidating satellite industry. On Monday, satellite giant Intelsat Ltd., which has most of its operations in the District, said it was acquiring PanAmSat Holding Corp. for $3.2 billion. Under the terms of the IDirect deal, the 11-year old Herndon firm will be acquired by Singapore Technology's U.S. holding company. IDirect will continue to operate under its own name and existing management team. No layoffs are expected among its 150 employees.

19. The iDirect GSM Backhaul Business Case • The implementation of GSM over satellite is commonly used in many regions of the world. Traditionally, this has been supported via a legacy SCPC connection (as depicted above). • In a point-to-point legacy SCPC connection, each link must be engineered to accommodate the busy hour traffic of the access BTS. • Satellite transmission however, is very bandwidth sensitive since every kHz of satellite bandwidth must be leased and incurs an additional cost. • Legacy SCPC provides a “brute force” method of solving Abis backhaul by throwing expensive bandwidth at the connectivity requirement. iDirect’s IP solution represents a natural evolution that will lead to significant bandwidth reductions, and therefore cost savings.
