Some researchers and futurists believe that multihop relay networks will eventually supplant technologies such as WiMax and LTE. With these networks, wireless signals will route themselves through a series of access points. Like the Internet itself, the route that the data takes is variable, depending on conditions.
"The network will find the best route and the best transmission mode," said Wen Tong, director of Nortel Networks' wireless technology laboratory. "I see initial deployment in three years."
A variant of the multihop relay network called ad hoc networks could come even later. With this technology, data would be relayed through, among other things, devices themselves. In other words, your phone will also be a movable access point.
"The defining quality of the ad hoc network is that it has no infrastructure," said Anthony Ephremides, a professor of electrical and computer engineering at the University of Maryland. "I'd guess it'll be [ready] in a five-to-10-year time frame."
Why it's import ????
