WiMax, Competitors Vie To Create Powerful EcoSystems
Several very interesting issues are at play in the rollout of wireless broadband technology. Indeed, the landscape that will dominate the next decade and beyond is being created now, as WiMax increasingly consolidates on one of two initial versions and steels itself for competition against other approaches.
The situation is fluid. Initially, the WiMax plan - to the extent that one existed - was for stationary and mobile versions to share center stage. Soon, however, it became clear that the mobile version could do just about everything the stationary version could. Thus, the impetus behind the stationary version began losing steam, said Monica Paolini, the founder and president of Senza Fili Consulting, in an IT Business Edge interview.
A lot of operators currently are deploying mobile WiMax. They are using it for fixed services. It's called mobile, but they can use it for both. On the other hand, fixed pretty much is just for fixed. Mobile WiMax allows you to roll out a network that supports fixed and mobile. The issue is having an infrastructure that can support all users. A lot of carriers will skip fixed WiMax, but offer fixed services using mobile WIMax technology.The big issue is what operators will do after 3G. Mobile WiMax is one option. Two others, according to this piece in internetnews.com, are LTE (Long Term Evolution) and ultramobile broadband (UMB). So far, WiMax has gotten most of the press, though the technology may be hitting a speed bump. Earlier this month, The Wall Street Journal speculated that Sprint, which had publicly anointed WiMax as its 4G technology, may be looking to make a deal with Clearwire, a company that now has a proprietary version of the platform in the field and will roll out the standardized version when it becomes available. While such a deal may make sense, it could be perceived as a diminution of Sprint's embrace of the technology.
This is a sector in which partnerships and joint ventures will be vital. Paolini thinks that a battle between LTE and WiMax will not be decided by a drastic difference between the technologies, but by the direction in which the industry, as a group, decides to go.
Both LTE and WiMax use OFDMA [Orthogonal Frequency Division Multiple Access]. Both have IP cores. There certainly are differences in the technology, but one is not a lot better than the other. Performance itself does not determine selection for mobile operators. It's more what the ecosystem is like, what the mobile community as a group wants to do.Though the race will be close, one technology will dominate because of the fundamental support of vendors, service providers and others.
We expect whichever direction they take, they will move together because then roaming is much easier.In this context, it's interesting that Paolini says it is likely that a new device will emerge. Cell phones and laptops are great, but neither is optimized to harness all the tremendous capabilities brought by wireless broadband.
But when you think about it, a laptop is a little too big to carry around all the time...most people just don't want to be bothered. On the other hand, a phone is a good device. Maybe a cellular phone has WiMax, but it is just an add-on that doesn't use the advantages of WiMax to the fullest extent. We need something in between, a data-centric device in a new form factor that allows you to capitalize on the advantages of mobile broadband. The other thing is to have consumer devices that have WiMax built in. It's a very good opportunity because the device is not likely to have a cellular interface.The two points are connected. On one hand, she says the "ecosystem" - the intricate web of vendors, service providers, integrators and other assorted companies - will be influential in the relative success of WiMax, UMB and LTE.
On the other, she says a new type of device will be a deciding factor. Clearly, device makers, along with the companies that make the chips and other elements that are packed into them, are key members of any ecosystem. The immediate future of this sector would be easy to predict if one of the technologies was far superior to the others. This isn't so; it will be a confusing and hotly contested arena until one platform takes control. The key will be to follow the ecosystem.

Broadband - What Next For Next-Gen?
Broadband has been a huge success in the UK, with half of all UK homes now with access to a connection.
But with a consumer call for a faster and more reliable service, and connection speeds falling behind countries like Japan and Sweden, suggested changes raised in a recent summit in London to discuss the future of broadband in the UK are still dividing opinion.
Plans for a future download speed of 24Mbps may seem fast for us, but with other countries around the world offering broadband deals, with connection speeds ranging from 40Mbps to even 100Mbps, could a change in infrastructure prove a turning point for broadband in the UK?
With the current broadband network based mostly on ADSL - a copper wire network designed to handle telephone calls - the demand for an increase in broadband speed could push the hardware to its limits. Other issues include noise on the line and falling connection speeds - causes for such disruption can include distance from the exchange and an increase in traffic on the network.
One of the issues facing any future plans for a fibre network in the UK would be ensuring that it would be open to all ISPs in much the same way as with LLU (Local Loop Unbundling) - which allows other cheap broadband providers the chance to put their services in BT telephone exchanges.
But even getting to that stage has been a long and complicated process, and with the demand for more cheap broadband increasing each year - a change in infrastructure could been seen as a way forward and ensure that the UK is compatible with the ever-changing Internet.
A new method of unbundling - known as sub-loop unbundling - could be necessary to the introduction of a fibre network, but would require operators to share space in street cabinets, which some believe to be unfeasible. There are also concerns that fibre networks would create another digital divide - much like the current scenario when it comes to rural broadband technology.
Wireless solutions such as Wimax could be seen to be a temporary solution, but there has been a widespread call for more government funding to help the progression of UK broadband, particularly to those in remote areas of the UK. Fibre connections would provide opportunities for a faster connection that would be welcomed by online gamers, networks which share video content, as well as the chance of delivering high-definition content - such as HDTV - via a broadband connection.
But with a number of problems still to be sorted within the existing broadband network - such as complications with ISP migration and actual connection speeds promised in broadband deals - the future of broadband in the UK remains an area of uncertainty.
