Smartphones strain networks worldwide due to boom in data traffic
Smartphones cause a larger than anticipated load on networks, according to a study by technology company Airvana.
Although smartphones generate much less mobile data traffic than a laptop with a data card, they impose a strain on the network, the study showed.
A boom in mobile data traffic, boosted by laptops and smartphones, is now putting unprecedented stress on networks around the world.
Delivering the same amount of data, a smartphone typically generates eight times the network signalling load of a laptop with a data card.
Global annual shipments of smartphone handsets are projected to increase from nearly 200 million in 2009 to 450 million in 2013, according to market research company iSuppli.
