It can transmit data at very high rates (for wireless local area network applications).
Within the power limit allowed under current FCC regulations, Ultra Wide Band can not only carry huge amounts of data over a short distance at very low power, but also has the ability to carry signals through doors and other obstacles that tend to reflect signals.
Securing Mobility
During the past five years security was a major issue in preventing the adoption of wireless and WLAN, however, recent developments are making wireless the best solution for many companies.
"Around 90 percent of laptops will be wireless by around 2006. There are still some challenges but they will be overcome in time," says Adrian Crouch, Strategy Technologist for Ericsson Australia. "You can have wireless networks all over the place but if they don't deliver a quality service then nobody will adopt them. And you have to have standards set up to ensure transition from one product to another when using the same type of wireless. You also have to make sure that there is a seamless handover when you transfer networks."Crouch says that speed upgrades will continue to make the business world's life easier and that we could easily see substantial speed upgrades within the next few years.
"We are looking at speeds of up to 100Mbps depending on what systems are being used. Ultra Wide Band will have incredibly fast wireless data transfer and will be used a lot in the consumer world for televisions, and so on," says Crouch. "There will always be a classic trade-off between speed and distance, but with the adoption of new wireless standards we will see more channels becoming available for high-bandwidth data transfer, which will greatly enhance the scalability of the network.
The battle begins
A recent survey by ABI Research shows that mobile telephony and WiMAX vendors may soon find themselves locked in competition for the same customers.
The telephone industry untethered fixed-line voice communications by making it wireless and mobile. Later as data became a significant portion of the communications, mobile designers modified their architectures and kept migrating up the data speed path.
In the GSM world we moved from the typical 40Kbps of GPRS to the 130Kbps of EDGE, the 384Kbps of UMTS, and now the upcoming 3Mbps of HSDPA, which finally makes mobiles a de-facto wireless broadband for voice and data.
From another angle, a suite of industry players have untethered fixed-line data communications such as DSL and cable and made them wireless; the standard they have formulated is WiMAX. They will also be able to do voice communications through VoIP. And the next extension of the standard will make it mobile. The result? WiMAX also equals mobile broadband for voice and data.
"It's only a matter of time before these two worlds colide," says Alan Varghese, ABI Research's principal analyst of semiconductor research. "HSDPA is an easy software upgrade from existing UMTS architecture, and mobile phone operators will be well on their way in 2005. WiMAX will need brand new networks and infrastructure, so the upfront costs and timelines may be more; but once deployed, WiMAX will offer very high bit rates and the possibility for new entrants to compete either using licensed or unlicensed spectrum."
And so the battle lines of the future are being drawn, pitting these two quite different technologies into the gladiatorial ring of users.
