I know there is one operator providing Pre-WiMAX even before the license spectrum is tendered.

We will offer high-speed broadband of up to 100mbps (megabits per second) for consumers and corporate Internet service of up to 155mbps for corporate customers, and small and medium enterprises over a wider geographical area by combining both REDtone and eB Tech's base stations and network capabilities," he said

A commonly held misconception is that WiMAX will deliver 70 Mbit/s, over 70 miles (112.6 kilometers) when the recipient is moving or mobile. Each of these is true individually, given ideal circumstances, but they are not simultaneously true. In practice this means that in line-of-sight environments you could deliver symmetrical speeds of 10Mbps at 10km but in urban environments it is more likely that 30% of installations may be non-line-of-sight and therefore users may only receive 10Mbps over 2km and if the recipient is on the move the bps rates drop significantly. WiMAX has some similarities to DSL in this respect, where one can either have high bandwidth or long reach, but not both simultaneously. The other feature to consider with WiMAX is that available bandwidth is shared between users in a given radio sector, so if there are many active users in a single sector, each will get reduced bandwidth. However, unlike SDSL where contention is very noticeable at a 5:1 ratio (if you are sharing your connection with a large media firm for example), WiMAX does not have this problem. Typically each cell has a whole 100Mbps backhaul so there is no contention here. In practice, many users will have a range of 2-, 4-, 6-, 8- or 10Mbps services and the bandwidth can be shared. If the network becomes busy the business model is more like GSM or UMTS than DSL. It is easy to predict capacity requirements as you add customers and additional radio cards can be added on the same sector to increase the capacity.

I thought even the Wimax specifications don't have 100 mbit?

Uh.... so should we start suing for false advertisement yet o_O; ?

Even the 70mbps is IMPOSSIBLE to achieve.

Operation WiMAX is underway, and carriers are spending some serious moolah on building out the networks. South Korea launched a WiBro network last year and in the U.S. Sprint and Clearwire are working on mobile WiMAX services, too. It's about time for some attention on the devices themselves, which are starting to get sold in South Korea, and in the U.S., likely some time in 2008. Here's some WiMAX goodies from Nokia, LG, Samsung, ZTE, and ZyXEL that should find their way to the market relatively soon.

Nokia: Nokia said on Monday that it will sell WiMAX mobile devices in early 2008. The Nokia folks told GigaTeam that the company's Internet tablet line would get a WiMAX version. Nice. My N800 does feel like its missing something.

LG: When I was at CTIA I got a chance to check out an LG WiMAX smartphone they were calling DBDM (dual band dual mode), that included 3G, WiMAX and DMB (mobile video broadcast) capabilities. Broadband overload - in a good way. The LG spokesperson at the booth said he thought Sequans was providing the WiMAX chip. The spokesperson also said the device goes on sale for around $700 in Korea "soon", and a similar device could land in the U.S. sometime next year.

Samsung: Samsung announced the availability of 3 mobile WiMAX devices last week for the Korean market - a WiBro smartphone, a converged mobile PC device, and a WiBro USB dongle. Sprint has also said that Samsung will develop PC cards with WiMAX and dual EVDO/WiMAX for the U.S. market.

ZTE Corporation: Sprint named ZTE as one of its suppliers of WiMAX devices including PC cards - express and USB - as well as modem products.

ZyXEL Communications: Sprint also named ZyXEL as a consumer device supplier, and ZyXEL will work on modem products. Not sure when these are coming online, but likely sometime next year.
