§ Mobitex (Blackberry) § OSI based packet switched data network developed in early 80 s used by the police and firefighters and the ilitary § Two way pagers

§ i. Burst § The HC-SDMA interface operates on a similar premise as GSM or CDMA 2000 for cellular phones, with hand-offs between HC -SDMA cells reportedly providing the user with a seamless wideband wireless experience even when moving at the speed of a car or train.

Wireless BAN

EVDO and HSDPA § EVDO up to 3. 1 Mbit/s § Sprint / Vrizon § HSDPA speeds of 1. 8, 3. 6, 7. 2 and 14. 4 Mbit/s

Canopy § Internet providers § 2 to 40+ miles Pt. MP, up to 124 miles Pt. P § Line of Sight

§ Wi. MAX § HIPERMAN (European ETSI alternative) § AP communication goes on a random interrupt basis and we face a problem of Qo. S with applicaions such as VOIP § Miscnception: Wi. MAX will deliver 70 Mbit/s over 50 kilometers

Wireless LAN § Wi-Fi - 802. 11 a/b/g/n § DSRC - 802. 11 p (Vehicular DOT network) § Fixed Wireless Data

Wireless PAN (802. 15) § § § Bluetooth Zig. Bee Ir. DA Wireless USB Wireless HD

Wireless HD § standard for consumer electronics, will allow for uncompressed, digital transmission of HD video and audio signals § theoretical data rates as high as 20 Gbit/s permitting to scale to higher resolutions, color depth, and range § point-to-point, non line-of-sight (NLOS) at up to 10 meters.

Wuzz. Bee - Wireless USB § 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters § game controllers, printers, scanners, digital cameras, MP 3 players, hard disks, flash drives, parallel video streams

Zig. Bee § IEEE 802. 15. 4 § Smaller and cheaper then Bluetooth § Low data rate, long battery life, secure networking § Headphones, sensors, industrial control

Fixed Wireless Data § Fixed Wireless Data is a class of technologies used to connect two fixed locations (e. g. , buildings) with a radio or other wireless link, such as laser bridge. Usually Fixed Wireless Data is part of a Wireless LAN infrastructure. The purpose of a Fixed Wireless Data link is to enable data communications between the two sites or buildings. Fixed Wireless Data links are often a cost-effective alternative to leasing fiber or installing cables between the buildings.

DSRC § Dedicated Short Range Communications is a short to medium range wireless protocol specifically designed for automotive use. It offers communication between the vehicle and roadside equipment. It is a sub-set of the RFID-technology. § 5. 9 GHz band (U. S. )
