Comba Telecom - Comba Launches Cell-Split Antenna Portfolio

Hospitality

Hospitality industry is a very broad industry as it consists of hotels, cruise ships, restaurants and anything that covers tourism or for leisure. In today’s high-tech world, mobile technology and social media act as the platform for businesses to promote their services and offerings for customers to make reservations through tablets and phone apps. Customers are also able to praise or critique their experience directly through social media. Hence the success of businesses is dependent on customer’s satisfaction and their praises for the services.

Comba Launches Cell-Split Antenna Portfolio

(6 January 2010 – Hong Kong) - Comba Telecom Systems Holdings Limited ("Comba" or the "Group", Hong Kong stock code: 2342), a leading wireless solutions provider, announced today the commercial availability of its new cell-split antenna portfolio to the global market. Compatible with 2G and UMTS networks, the latest antenna solution from Comba allows operators to increase its network capacity with minimal incremental base station investment, thereby offering operators a compelling value proposition for cost savings.

Developed through intense research and development at Comba's R&D facilities, the cell-split antenna enables higher capacity through flexible high order sectorization (HOS) that optimizes frequency reuse in the traffic channel. Studies have indicated that through optimized frequency reuse in traffic channels, HOS can almost double the capacity of GSM and UMTS networks when deployed. Featuring a robust and compact chassis, the cell-split antennas are designed for maximum flexibility and ease of installation, thus enabling rapid deployment with small footprint for both new network rollouts and capacity expansion in existing networks.

For capacity expansion in existing networks, deploying Comba's high gain, cell-split antennas allows operators a rapid and inexpensive doubling of capacity option, and more importantly to defer adding further base station sites and the associated site acquisition costs. The cell-split antenna is especially suitable for new network rollouts since it enables operator maximum flexibility in scalability and network optimization with faster payback times on BTS site and node B investments.

Ms Carol Ye, Director of Comba's Antenna and Subsystems division said, "We are pleased to bring our latest antenna featuring cell-split technology to the market. In the current market conditions, operators are frequently facing the dilemma of minimizing the financial bottom line against addressing demands on network capacity which traditionally requires significant investment. Comba's high gain, cell-split antennas help address this issue with an efficient and cost-effective solution."

Ms Ye concluded, "In fact this is a market-proven solution - the cell-split antenna had been undergoing in trials with a number of operators over the past few months, with positive feedback. We are pleased to say that we have recently received a significant order for a large number of cell-split antennas from an operator in India."
