A wireless communication In this framework, it allows the sending of data from a sender to a receiver without an agent connecting the two points physically. This type of technology it uses a certain frequency band and low-power radio frequency waves to achieve the transmission of information.
A wireless phone , meanwhile, is a device that connects to a base Without using a cable. This base, in turn, has a connection to a fixed telephone network and an electrical outlet.
Cordless phones have batteries rechargeable . The user can move up to about 100 meters from the base with the cordless telephone and make or receive calls. In this way you have the possibility to communicate with greater comfort, without so many physical limitations.
