4G to drive up wireless infrastructure expenditures

What is wireless communication?
Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires." The distances involved may be short (a few metres as in television remote control using infrared light) or long (thousands or millions of kilometres for radio communications).

What is 4G?
4th generation technology that will provide voice, data and streamed multimedia to users on an “anytime, anywhere” basis, and at higher data rates than current generations allow. Objectives for 4G include wired and wireless technologies capable of providing 100Mbps and 1Gbps speeds both indoors and outdoors. 4G will succeed current 3G WCDMA/HSDPA/HSUPA technology.
