BridgeWave Issues Top Five Backhaul Considerations for Carriers Looking to Exceed Subscriber Expectations
4G Backhaul Must Be More Than a "Fat Pipe" So Network Performance Does Not Lag Behind Handset Innovation
Santa Clara, Calif. – May 12, 2010 – BridgeWave Communications, the leading supplier of gigabit wireless solutions, today issued the top five considerations for mobile carriers as they select network equipment in their migrations to 4G networks. Carriers must support the exponential growth of mobile traffic created by data-hungry smartphones and the consumer expectations that come with them. Carrier mobile backhaul must not only offer far greater bandwidth, at gigabit capacities or greater, but also provide "service aware" network functionality.
Below are five considerations for carriers as they consider next-generation functionality in their move to 4G networks:
All backhaul is not equal
Higher frequency millimeter wave (70/80 GHz) mobile backhaul equipment is well suited to offer multi-gigabit transmission rates, at a lower total cost of ownership (TCO) per megabit needed to support data-hungry phones. Next-generation networks spur dense base-station deployments requiring more backhaul capacity beyond what today's networks offer. Carriers must consider their near-term and long-term objectives when evaluating backhaul and ensure the infrastructure installed today can be easily upgraded tomorrow.
Ensure weather doesn't get the network down
While microwave radio is not fully immune to rain, functionality can be provided that helps mitigate the effects of rain and allows carriers to maintain high-availability transmissions. Simply providing more system gain does not always yield desired results, but technology like adaptive rate and modulation ensures that calls or data connections are not dropped despite inclement weather.
Deliver real-time applications at the right time
More and more VoIP and video apps need quality of service (QoS) on mobile networks so they are prioritized to perform well. The newest iPhone OS will support more gaming and VoIP meaning real-time application performance is gaining in importance. Backhaul solutions should yield this "service aware" functionality to ensure that service level agreements (SLAs) are met.
Limit network interference
As the use of 70/80 GHz solutions becomes a critical part of the infrastructure, carriers will want to limit interference by finding equipment able to tune throughout the entire 70 and 80 GHz RF band. This requires frequency agility that eases RF network planning for dense cell site deployments and mitigates interference.
Better management for better performance
Via Ethernet Operation, Administration, and Maintenance (OAM) functionality, carriers can automate end-to-end network management and monitoring to validate connections, detect faults and alarms, and monitor link performance. With OAM, network troubleshooting is streamlined meaning maintenance costs and efforts are reduced for a more reliable network and happier subscribers.
"As carriers move to 4G, BridgeWave supports them in their quest to exceed the already high expectations of subscribers, leading to these considerations," said Paul Obsitnik, senior vice president of business development of BridgeWave. "With many new smartphones and real-time apps coming to market, carriers needn't fear the onslaught of traffic as network solutions are available to keep them one step ahead of handset demands and consumer desires."
BridgeWave's Paul Obsitnik will present these recommendations to network operators preparing for LTE evolution at Transport Networks for Mobile Operators, taking place in London on Monday, May 17. Obsitnik will discuss the impact of LTE on the current design of today's transport infrastructure and provide practical steps towards preparing networks for LTE. His presentation will assess the key tools that are needed to fully support LTE backhaul, including utilizing higher frequency millimeter wave and limiting network interference.
