Why 4G Speed Matters
As smartphones and tablets developed the capability to stream video and music, the need for consistent and sustained data bandwidth grew in tandem. Previously, cellular speeds were much slower than the high-speed broadband connections to computers. Given that most cellular data focused on mobile-optimized browsers and very simple apps, they didn’t need large data pipes. 4G speed compares favorably with some broadband options and is particularly useful in areas without broadband connections.
4G Technology
While all 4G service is called 4G or 4G LTE, the underlying technology is not the same with every carrier. Some use WiMax technology for their 4G network, while Verizon Wireless uses a technology called Long Term Evolution, or LTE. Sprint says its 4G WiMax network offers download speeds that are ten times faster than a 3G connection, with speeds that top out at 10 megabits per second. Verizon’s LTE network delivers download speeds between 5 Mbps and 12 Mbps. T-Mobile’s varies between 7 Mbps and 40 Mbps.
What Comes Next?
Soon, the companies touting WiMax and LTE networks will be talking about IMT-Advanced technology, which will deliver 5G speeds. The technology is expected to be faster, have fewer dead zones, and end data caps on cellular contracts. The rollout will probably begin in large urban areas.
