A second-generation standard for WiMAX now under development by the Institute of Electrical and Electronics Engineers promises 100 Mbps downstream bandwidth.
The 802.16m standard will significantly boost first-generation WiMAX speeds. Sprint’s Xohm network generally supports speeds between 3.7 Mbps to 5 Mbps.
Significantly, the speed boost will be possible over the same distances WiMAX now operates over. WiMAX covers about 31 square miles from each access point.

LTE Transport Cost 1/3 to 1/2 That of 3G

The cost of carrying one megabyte of data over its LTE network would be half to one third the cost of carrying the same data over the company’s current 3G network, Lowell McAdam, Verizon Wireless’ CEO, says. That is going to be good news both for users and mobile services providers.
Bandwidth services providers universally need to improve the efficiency of their networks, since increased data consumption typically involves non-linear revenue effects. In other words, providers earn less money, on a revenue-per-bit basis, the higher the amount of bandwidth they provide.
And though consumers will not likely appreciate a gradual shift to buckets of usage, so long as the plans, pricing and consumption patterns are relatively closely matched, people can adapt. People are used to buckets of voice and text messaging, for example.
But key to crafting such plans is that they are viewed as fair. A lower cost, higher capacity network that works better for key applications such as voice and video is a likely prerequisite.
User patterns also are changing. Unlimited plans work quite well for users and providers when consumption is low. But most users consume more bandwidth over time, driven especially by video use, which requires an order of magnitude to two orders of magnitude more capacity than voice, for example.
Verizon’s coming shift to buckets of usage for multiple devices also makes sense. As users shift to use of broadband for multiple devices, they will not prefer paying for access to each discrete device. Also, usage profiles vary by device.
Cameras and e-book readers will not typically demand much bandwidth. Nor will voice applications. Smartphone web browsing will consume more, but smartphone data consumption typically is far less than from a PC. Blending usage from a range of devices, and allowing consumers to pay once, for access on all the devices, will save users money and provide more value while at the same time allowing service providers to offer service on terms that are sustainable.

World’s 2nd-Largest WiMAX Network Switches to LTE

World’s 2nd-Largest WiMAX Network Switches to LTE
Russia’s Yota network, which connects 300,000 people over WiMAX technology, is switching to LTE, and plans to spend $2 billion migrating its network to the different air interface.
Backed heavily by Intel, which hoped to make WiMAX as ubiquitous as Wi-Fi, the tide turned in favor of LTE when virtually all the world’s mobile service providers decided to back LTE instead of WiMAX.
WiMAX had a headstart getting to market, but LTE now has closed the gap. Early adopters argued that they had to get to market fast, so WiMAX made sense. But the rival LTE air interface now stands to garner so much production volume that it now makes more sense, going forward, even for early adopters such as Yota.
Yota should be able to upgrade using software, some argue, as the Samsung-supplied base stations Yota uses can support both FDD-LTE and TD-LTE, and Yota uses spectrum well suited to the time division variant of LTE.
The new LTE network will start in Kazan, Novosibirsk and Samara, with Moscow and St. Petersburg to follow by the end of 2011. The 15 cities previously scheduled for WiMAX deployment will go straight to LTE.
