Wi-Fi Capacity and New Devices
A recent NY Times article reported that hotel Wi-Fi capacity was again being challenged, this time by iPads and other tablets, or more specifically, tablet users. The Times notes that these users may have a smart phone and laptop going at the same time they are sucking up streaming video. The high bandwidth demand of these devices, or more specifically, their uses, is said to be reducing download speeds back to the good old days of dial-up connections. A likely solution will be a tiered charge structure, similar to the newest cellular data plans, with the result that you can waste bandwidth if you don’t care what it costs. A more general report on current and future wireless demand versus capacity has been produced by the Global Information Industry Center at the University of California San Diego. A less foreboding report on medical uses of Wi-Fi has been produced by the Wi-Fi alliance.
Smart phones have a prior history of overwhelming cell phone networks, such that in dense environments someone can’t make a phone call because too many other people are watching reality show reruns and bad movies. Now some cellular devices have been looking at switching to Wi-Fi when it is available, as explained here. This leads to the conflict ridden situation of cellular wanting to use Wi-Fi to solve its capacity problems at the same time that Wi-Fi is being over loaded by other devices. Cellular resistant building structures, which are increasing, also can create a desire to shift to Wi-Fi.
