Wireless Systems Communications

Wireless Systems Communications Introduction Wireless Systems Communications is the process of fully transforming how individuals and institutions across various sectors (that are not physically connected) communicate - and how they receive and exchange information. Wireless systems are rapidly rendering a wide range of personalized communications services as portable as cellular phones. Many of today’s most promising new wireless technologies involve Wireless Local Area Networks (WLANs), which enable a wide range of communications devices to stay connected to more conventional wired networks without requiring users to be physically connected through wires or cables. Through widely spaced access points, WLANs receive and transmit radio signals to and from Network Interface Cards (NIC) that contain small radio receivers and transmitters attached to users’ computers or other communications apparatuses.
