A recent advisory report to the White House made that clear enough, and it emphasized that sharing wireless frequencies more widely—rather than parceling each band out to a limited set of users—could increase wireless capacity by a factor of thousands. Five years of full-time, progressively responsible field-related experience in network maintenance with a variety of network devices; with one of the five years, experience with DDNS, VPN, and firewalls desired.
Here are the four primary ways they're going about staving off a spectrum crisis and the resulting cell phone apocalypse. One way to relieve capacity jams is "cell splitting," which involves either adding more cell sites or adding more radios to existing sites to increase the number of connections that a network can handle. The problem is that it's expensive and tricky. They face practical hurdles: Interference is also a growing problem as more towers get added.
There are, however, some innovative solutions being developed. Alcatel-Lucent ALU introduced lightRadio a year ago, taking all the components of an antenna and base station and cramming them into a cube that fits in your palm. The company is working with carriers to deploy the devices throughout capacity-constrained metro regions, placing them in spots like on top of telephone poles and on the sides of buildings.
New network technologies can get those trucks to drive much closer together, freeing up capacity. The problem is that the vast majority of cellular customers don't have 4G-capable devices. LTE has nowhere near the same level of national coverage as less-efficient 2G and 3G services.
Even if carriers offered incentives to get customers to buy 4G phones, they would still need their 2G and 3G networks to keep users connected in non-4G areas. Down the road, some analysts predict that even 4G's extra capacity won't be enough. Another solution is to simply get customers to stop using so much spectrum. It's easier to cram a lot more data into wires than into airwaves -- that's why your home broadband is generally much faster than your smartphone.
Vastly more frequencies are reserved for other uses, from television and radio to aviation and military applications. Data traffic is growing so rapidly that carriers have imposed usage caps and raised prices. Surely, these two basic realities—exploding data use on the one hand, limited bands of spectrum on the other—must mean we will soon run out of airwaves for our gadgets, right? Just two years ago the chairman of the U.
Federal Communications Commission, Julius Genachowski, suggested as much. He said the U. Otherwise, wireless companies would find that demand for their services would outstrip their ability to provide them.
Sometimes, alternative strategies can completely solve these localized problems. These are short-range Wi-Fi receivers, operating on unlicensed portions of the radio spectrum. Your phone can send data through them instead of on the long-range cell-phone frequencies.
The Wi-Fi boxes mop up all the data you send, and route it out of the stadium over a wired Internet connection. That clever trick is just one example of the new strategies and technologies that can be brought to bear. Things Reviewed Report to the President: A recent advisory report to the White House made that clear enough, and it emphasized that sharing wireless frequencies more widely—rather than parceling each band out to a limited set of users—could increase wireless capacity by a factor of thousands.
For example, many sections of the airwaves that are reserved for TV stations and federal agencies go unused.
