Study Notes
Wireless Networks and Mobility
- WLANs enable mobility in home and business settings, adapting to changing needs and technology.
Types of Wireless Networks
- WPAN (Wireless Personal-Area Network): Short-range (20-30 ft or 6-9 m), based on IEEE 802.15. Examples include Bluetooth and Zigbee.
- WLAN (Wireless Local Area Network): Medium range, up to about 300 ft, based on IEEE 802.11.
- WMAN (Wireless Metropolitan Area Network): Covers larger areas (cities/districts) using specific licensed frequencies.
- WWAN (Wireless Wide Area Network): Great for national/global communication with specific licensed frequencies.
Wireless Technologies
- Bluetooth: Utilizes IEEE WPAN for device pairing up to 300 ft (100 m); includes BLE for mesh networks and BR/EDR for audio streaming.
- WiMAX: Provides broadband internet connections over long distances using the IEEE 802.16 standard, covering up to 30 miles (50 km).
- Cellular Broadband: Integrates voice and data for mobile devices, including GSM (global standard) and CDMA (commonly used in the US).
- Satellite Broadband: Requires directional dishes, ideal for rural locations lacking cable/DSL connections.
802.11 Standards
- 802.11 standards dictate radio frequency usage for wireless links, including security features like SSID cloaking and MAC address filtering.
- Supported authentication techniques include WEP, WPA, WPA2, and WPA3.
New Terms and Commands
- Key terminologies include WPAN, WLAN, WMAN, WWAN, Bluetooth, 802.11 standards, SSID, and various wireless security protocols like WPA and AES.
Wireless Standards Organizations
- ITU (International Telecommunication Union): Regulates radio spectrum allocation and satellite orbits.
- IEEE (Institute of Electrical and Electronics Engineers): Establishes specifications for radio frequency modulation, governs LAN/MAN standards.
- Wi-Fi Alliance: Promotes WLAN growth and interoperability among devices.
WLAN Components and Functionality
- WLANs utilize unlicensed radio spectrum for data transmission using various technologies.
- Operate on the 2.4 GHz and 5 GHz frequency bands.
- CAPWAP allows Wireless LAN Controllers to manage multiple Access Points.
- DTLS ensures security between Access Points and the Controller.
Wireless Transmission Basics
- Wireless devices use specific radio frequency channels (DSSS, FHSS, OFDM) to transmit and receive data.
- 802.11b/g/n standards utilize frequencies between 2.4 GHz and 2.5 GHz, with each channel having 22 MHz bandwidth and 5 MHz separation.
Security and Threats
- Wireless networks face risks like data interception, unauthorized access, DoS attacks, and rogue Access Points.
