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

5  iBurst  The HC-SDMA interface operates on a similar premise as GSM or CDMA2000 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.  iBurst  The HC-SDMA interface operates on a similar premise as GSM or CDMA2000 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.

8 Canopy  Internet providers  2 to 40+ miles PtMP, up to 124 miles PtP  Line of Sight  Internet providers  2 to 40+ miles PtMP, up to 124 miles PtP  Line of Sight

9  WiMAX  HIPERMAN (European ETSI alternative)  AP communication goes on a random interrupt basis and we face a problem of QoS with applicaions such as VOIP  Miscnception: WiMAX will deliver 70 Mbit/s over 50 kilometers  WiMAX  HIPERMAN (European ETSI alternative)  AP communication goes on a random interrupt basis and we face a problem of QoS with applicaions such as VOIP  Miscnception: WiMAX will deliver 70 Mbit/s over 50 kilometers

10 Wireless LAN  Wi-Fi - 802.11 a/b/g/n  DSRC - 802.11p (Vehicular DOT network)  Fixed Wireless Data  Wi-Fi - 802.11 a/b/g/n  DSRC - 802.11p (Vehicular DOT network)  Fixed Wireless Data

11 Wireless PAN (802.15)  Bluetooth  ZigBee  IrDA  Wireless USB  Wireless HD  Bluetooth  ZigBee  IrDA  Wireless USB  Wireless HD

12 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.  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.

13 WuzzBee - 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, MP3 players, hard disks, flash drives, parallel video streams  480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters  game controllers, printers, scanners, digital cameras, MP3 players, hard disks, flash drives, parallel video streams

14 ZigBee  IEEE 802.15.4  Smaller and cheaper then Bluetooth  Low data rate, long battery life, secure networking  Headphones, sensors, industrial control  IEEE 802.15.4  Smaller and cheaper then Bluetooth  Low data rate, long battery life, secure networking  Headphones, sensors, industrial control

15 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.

16 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.)  Dedicated Short Range Communications is a short to medium range wireless protocol specifically designed for automotive use.
