Backhaul:
The Bandwidth Explosion in Wireless Networks
New York
- Growth of mobile networks across the globe has forced
operators to engage in aggressive backhaul upgrades due to changing traffic
attributes, cost challenges and increasing capacity requirements, according to
a new study by Visant Strategies.
The current migration to faster data-oriented air interfaces such as HSDPA, EV-DO and even WiMAX is causing backhaul needs and costs to rise significantly as carriers must support more capacity and greater complexity, the report finds.
"Backhaul capabilities will be enhanced greatly during the next years, a pattern that has already began," said author Andy Fuertes of the new report "Global Backhaul: The Bandwidth Explosion in Wireless Networks."
"For
example," Fuertes said, "over three quarters of all deployed base stations globally
employ 6 Mbps or less of backhaul capacity today, well within the capabilities
of traditional E1/T1 technology. But that will be a thing of the past as the
majority of base stations deployed in leading mobile markets will have much
higher backhaul capacity, increasing by a factor of from two to five through the
years."
"The greatest challenges for operators may be evident just outside of the urban fiber rings within leading wireless economies. Sites in these areas typically lack access to fiber but their capacity requirements will increase substantially," Fuertes added.
"Another critical factor is the rising rate of collocation of base stations in tandem with the rise in capacity per base station," said Larry Swasey of Visant Strategies. "As collocation becomes more of a must each year during the study period, towers requiring 45 Mbps or more of total capacity will almost double each year during the same period."
The report details base station deployments, wireless sites, backhaul lines by capacity and access technology, sites by capacity, backhaul costs, and deployment of IP-centric base stations by region through 2012. It also examines air-interface use, network traffic developments and subscriber usage patterns creating the need for the increased backhaul capacity.
