Computer News Middle East: Cognizant’s Vice President and Practice Leader for Communications Says Fiber is Among the Best Backhaul Solutions

“Fiber is one of the best backhaul solutions to support the burst nature of data traffic generated due to transport of quality-sensitive services such as video calling, movie-on-demand, and interactive services,” says Balakrishan Shanmugham.

“Fiber deployment is a one-time exercise that can support multiple iterations on bandwidth expansion by deploying various logical resources. Therefore, it is more cost-effective in increasing backhaul capacity than any other mechanism such as copper, which provides limited ability to enhance bit rates while retaining traffic quality in a long-haul network,” he adds. 

Shanmugham says wireless backhaul is good to support immediate backhaul requirements, provided the mobile network is 2G or sub-3G variant and has moderate data growth rate (around 10 to 15 percent). It also depends on the terrain and operating conditions.

“Wireless backhaul may start facing limitations if customers start using bandwidth-hungry applications or quality-sensitive interactive services,” he says.
