2.3 Wireless Network Technologies

Flashcards covering key concepts related to IEEE 802.11 wireless networks and Bluetooth technology.

802.11 Standard

A set of technical specifications for wireless communication networks.

Frequency Ranges

Commonly include the 2.4 GHz and 5 GHz bands used for wireless communication.

2.4 GHz Band

A frequency range with channels 1, 6, and 11, commonly used by many wireless networks.

5 GHz Band

A frequency range with more available channels than the 2.4 GHz band, allowing for better throughput.

Wireless Channels

Specific frequencies assigned by the IEEE for use in 802.11 networks.

Channel Management

The practice of setting different access points to different channels to minimize interference.

Regulatory Agencies

Government entities that manage the wireless spectrum and set usage regulations.

Interference Limitations

Regulations that limit how much interference can be caused by wireless networks.

Bandwidth

The capacity of a wireless channel, which can be 20 MHz, 40 MHz, 80 MHz, or 160 MHz.

Throughput

The amount of data transmitted successfully over a network in a given time.

Personal Area Network (PAN)

A small network, typically within 10 meters, for personal devices.

Bluetooth Technology

A wireless technology standard used for short-range communication of personal devices.

ISM Band

Industrial, Scientific, and Medical band within the 2.4 GHz range that is unlicensed.

Access Points

Devices that allow wireless devices to connect to a wired network.

Signal Range of Bluetooth

Typically around 10 meters for consumer devices, and can exceed 100 meters for industrial devices.

Channel 1, 6, and 11

The only three channels available for 2.4 GHz networks.

Spectrum Management

The regulation and assignment of frequency bands for different technologies.

High Throughput

A feature of the 5 GHz band that allows for larger data transmission sizes.

Frequencies

Specific electromagnetic wave frequencies assigned for various communication purposes.

Interference

The disruption caused by multiple devices operating on similar frequencies.

Multiple Access Points

The use of several access points in one area to improve network coverage.

IEEE

Institute of Electrical and Electronics Engineers, responsible for developing wireless standards.

Bluetooth Devices

Peripherals like headsets, speakers, and keyboards that use Bluetooth for connectivity.

Consumer Devices

Bluetooth technology application geared away from industrial use, limited to 10 meters.

Regulatory Compliance

Adhering to legal requirements set by authorities for wireless communications.

5 GHz Channels

More numerous channels in the 5 GHz range compared to 2.4 GHz, allowing less interference.

Channel Width

The measurement of bandwidth used in wireless communication, impacting data speed.

Short-range Communication

The typical limitation of Bluetooth devices to communicate over short distances.

Bluetooth Standards

Specifications that define the operation of Bluetooth technology, including range and capabilities.

Device Connectivity

The ability of peripherals to connect without wires using wireless technology.

Non-Contiguous Areas

Segments that can be used for wide bandwidth communication in the 5 GHz spectrum.

Wireless Spectrum

The range of electromagnetic frequencies used for transmitting data wirelessly.
