Mobile vocabulary
- 3GPP2: standardization organization in charge of mainly CDMA2000 and its succesive technologies
- 3GPP: standardization organization in charge of UMTS and its succesive technologies
- Ad Hoc network: in this case for mobile uses, a self-configured network by the user's terminals themselves
- Bluetooth: wireless technology for short range communications (between handset and headset e.g.)
- CDMA2000: broadband wireless system based in CDMA, mainly used the US e.g.
- CDMA: radio techique based on multiplexing specific codes for each user
- DECT: digital standard widely used for portable phones
- EV-DO: evolution of CDMA2000 that enhances the downlink performance
- FOMA: broadband wireless system for third generation used in Japan
- GPRS: modification of GSM to carry packet communications (more suitable for data)
- GSM: second generation (digital) mobile system, worlwide succesful specially in Europe
- HSDPA: modification of the WCDMA applied in UMTS to share resources and gain performance in the downlink
- HSUPA: modification of the WCDMA applied in UMTS to share resources and gain performance in the uplink
- IMT-2000: global definition for all the 3G (third generation) standard by the International Telecommunication Union
- LMDS: broadband wireless access system working point-to-multipoint mainly in rural environments
- MIMO: radio technique based on multiple transmitters and receivers
- OFDM: radio technique based on multiplexing narrowband frequencies, that minimizes interference between carries
- UMA: wireless system that allows to make seamless handover between local and wide area networks (also known as GAN)
- UMTS: broadband wireless system that came after GSM, and mainly used in Europe e.g.
- UWB: radio technique that uses a large shared bandwidth and normally has a short range
- WiFi: wireless local area network, high speed but limited coverage
- WiMAX: high speed wireless wide area network, based on the IEEE 802.16 standard
- WLL: radio technique for a user's local loop (network access point)
