Wireless USB and CableFree USB vie for dominance in personal area networks.
One of the year's hottest mobile technologies might never leave your desk. Based on a spec from the Intel-led WiMedia Alliance, Wireless USB is intended to replace the morass of cables linking PCs to cell phones, PDAs, and MP3 players. Think of it as Bluetooth, but better: It's based on new Ultra Wideband radio technology, which is faster than Bluetooth and uses less power. At top speed, it beams a CD's worth of data in about 10 seconds.
But Ultra Wideband's journey from the lab to the electronics store hasn't been easy. A rival group, the UWB Forum, has a seemingly identical technology called CableFree USB. The first products based on Wireless USB and CableFree USB--radio-based dongles that attach to USB ports and replace USB extension cables--will ship this summer. Laptops, digital cameras, and printers with the radio technology will come later, in time for the holidays.
But while radio dongles based on the competing specifications look the same and do the same thing, they can't talk to each other. Worse, they jam each other's transmissions so they can't even share the same air space.
2014 Next-Gen WAN SurveyWhile 68% say demand for WAN bandwidth will increase, just 15% are in the process of bringing new services or more capacity online now. For 26%, cost is the problem. Enter vendors from Aryaka to Cisco to Pertino, all looking to use cloud to transform how IT delivers wide-area connectivity.
The UC Infrastructure TrapWorries about subpar networks tanking unified communications programs could be valid: Thirty-one percent of respondents have rolled capabilities out to less than 10% of users vs. 21% delivering UC to 76% or more. Is low uptake a result of strained infrastructures delivering poor performance?
