Guide to Wireless Technology - Chapter 1 notes

These flashcards cover key terms and concepts related to wireless communications technologies and their applications.

Wireless Communication

The transmission of digital data while connected to some type of data network, without the use of wires.

Wi-Fi

A wireless local area network (WLAN) that enables access to digital-data-enabled devices on a network.

Bluetooth

A wireless technology designed for very short ranges, typically a few inches to 33 feet, to eliminate cables between devices.

ZigBee

A wireless communications specification based on IEEE standard 802.15.4, designed for applications requiring long battery life.

RFID

Radio Frequency Identification, a short-distance wireless technology developed to replace barcodes.

NFC

Near Field Communication, similar to RFID, intended to operate at a distance of about 2 to 4 inches for data exchange.

Cellular Networks

A technology that uses low-power transmitters spread throughout a geographical area to maintain connectivity while out of range of Wi-Fi.

WiGig

A short-range wireless technology that transfers video and sound at speeds of up to 7 Gbps using Ultra Wide Band (UWB).

Digital Convergence

The ability of digital devices to combine voice, video, and text processing capabilities while being connected to networks and the Internet.

Advantages of Wireless Networking

Includes mobility, easier installation, increased reliability, and better disaster recovery options.

Challenges of Wireless Networking

Includes security risks, potential health risks from RF exposure, and the challenges of managing network reliability.
