...while the world waits for WiMAX, wireless operators in Sydney, Johannesburg, Paris and the Bay Area are already deploying ArrayComm's new antenna design, to the dismay of mobile carriers. Conventional mobile antennae, Cooper says, "are really just a bunch of sticks - we make them smart.'' Where conventional masts send out signals in circular arcs - a process that wastes transmission power because only the signals that hit a phone are used - an ArrayComm antenna transmits signals in a straight line, targeting a particular phone that it recognizes using specialized software. Cooper says ArrayComm's software, which resides in computers...
...operators struggle to make those four-year-old investments pay off, they're not about to switch to ArrayComm. Although ArrayComm was able to license its technology to Chinese and Japanese operators that deploy a more compatible mobile-phone system, Western operators have declined. So ArrayComm is selling to wireless Internet providers like Sydney's Personal Broadband Australia (in which ArrayComm is a partial owner) that are in various stages of covering cities like Sydney, Melbourne and Brisbane...
...Another wireless challenge is in the home. Although households, especially in the U.S. and Asia, are increasingly popular places for wireless networks, wi-fi has difficulty handling large video files. That's because its speed is not always fast enough to transport movies without glitches; you may have noticed the problem when trying to beam Bridget Jones's Diary from the computer in your living room to your TV in the corner. Several companies are working to develop another wireless technology called UWB (ultra wide band) that provides 10 times the bandwidth of wi-fi. Although UWB signals...
...Like many consumer technologies, UWB started out as military technology, used for communications that avoided eavesdroppers by spreading over a very wide range of frequencies. Yaish, 39, became familiar with it when he served in the Israeli army in the early '90s as a wireless specialist. Today, he and other UWB proponents are honing a standard they hope will assure that all UWB devices communicate in the same way. Wisair is part of a large contingent backing one proposed standard, while Freescale, the chip company carved out of Motorola, backs another. The existence of competing standards means that market forecasts...
...able to understand, however, is the apparent disconnect between the size of these budgets and the enormous amount of money which Harvard has in its name. Cable television is probably not an important part of the undergraduate experience here. Maybe we don’t really need wireless Internet access on every square foot of campus. Harvard certainly does spend money in the truly important places: We have the best paid and arguably most distinguished faculty of any school in the country (or maybe even the world), and I’ve had, overall, fantastic experiences with the teachers, tutors...
