Wireless data

Wireless data refers to transmitting information—voice, video, sensors, apps—without physical cables, using electromagnetic waves like radio, microwave, or infrared waves.

Technologies and networks

Wi‑Fi (Wireless LAN)

Connects devices via access points using IEEE 802.11 standards.
Latest versions include Wi‑Fi 6/6E (using 2.4 GHz, 5 GHz, and now 6 GHz bands) offering higher throughput and efficiency

Cellular (3G/4G/5G/5G‑Advanced)

3G/4G (LTE) support broad data access.
5G launched globally since 2019; offers up to 10 Gbps speeds, extremely low latency, and supports massive IoT
5G‑Advanced (5.5G) introduces AI integration, edge compute, better slicing, non-terrestrial networks, aiming for full deployment by end of 2025.

Wireless PAN and others

Bluetooth, Zigbee, UWB for short-range, low-energy data transfer (e.g., device pairing, indoor location)
Satellite and Wide Area IoT networks (e.g., NB-IoT) allow remote connectivity

Niche and emerging

IEEE 802.22 uses TV bands for rural broadband with AES-GCM encryption
Free-Space Optical (FSO) Infrared beams achieved 5.7 Tbps over 4.6 km—no RF needed
6G (2027–30) envisions terahertz bands, AI-native networks, quantum comms, holographic beamforming

Security and protocols

Wi‑Fi encryption

There are four main methods of Wi-Fi Encryption:

WEP: outdated and insecure.
WPA & WPA2: added TKIP and AES/CCMP, respectively
WPA3: modern standard since 2018 with SAE, enhanced open (OWE), 192-bit enterprise, and protection of management frames

Trends in wireless security

The trend in wireless security is to move toward WPA3, Wi‑Fi 6E enhancements, private 5G/LTE (CBRS), UEM, AI/ML analytics, edge protection, and stronger identity access management.

Architecture and standards

OSI layers

Wireless networks conform to the OSI model, each layer bringing unique threats and protections.

Protocol stacks

Wireless Application Protocol is the early mobile web stack (WSP/WDP/WTP/WTLS) designed for feature phones and constrained networks.^{[citation needed]}

Applications and use cases

Consumer Internet access: Home Wi‑Fi and mobile broadband
Enterprise mobility: BYOD management, secure campus networks
IoT and industrial: Sensors, telemetry, remote control via Zigbee, private LTE, NB-IoT
High-speed links: FSO for urban backhaul; IEEE 802.22 for rural broadband
Future systems: 5G/6G to support smart cities, autonomous vehicles, XR, remote surgery
