A2DP:ADVANCED AUDIO DISTRIBUTION PROFILE
The Advanced Audio Distribution Profile specifies the protocols that outline the distribution of prime quality audio content in Asynchronous Connectionless Link (ACL) channels.
AAS:ADAPTIVE ANTENNA SYSTEM
Adaptive Antenna System (AAS) otherwise called Advanced Antenna System may be a technology to alter the network operators to extend the capability of wireless network systems. In addition to it adaptive antenna systems provide the potential of increased spectrum potency, extended variety of coverage and better rate of frequency use.
AAS consists of multiple antenna components at the sending and receiving facet of the communication link, whose signals square measure processed adaptively so as to take advantage of the spatial dimension of the mobile radio channel. counting on whether or not the process is performed at the causing finish or receiving finish or each ends of the communication link, the adaptive antenna technique is classed as one.multiple-input single-output (MISO), 2.single-input multiple-output (SIMO) or multiple-input multiple-output (MIMO).
In wireless communications,air interface is the frequency portion of the network that transmits signals between base stations and user-end instrumentality. The air interface is outlined by specifications for a particular format like GSM, CDMA2000.
BACKHAUL: In wireless technology, backhaul refers to transporting voice and knowledge traffic from a cell web site to the switch.
Bose-Chaudhuri-Hocquenghem (BCH) Code may be a family of powerful cyclic block forward error correction codes employed in the transmission of information.
EPOC is a software package optimized for itinerant uses. It was developed by Symbian, which may be a joint company of Psion, Nokia, Ericsson, Motorola and Panasonic. EPOC turns voice-oriented handsets into Mediaphones. EPOC places a lighter load on the processor compared to personal organisers in operation systems and so has the capability to reinforce the multimedia system capability of mobile phones.
Extended Total Access Communication System E-TAGS is an extension of the TACS (Total Access Communications System) through the allocation of extra radio channels.
Fixed wireless refers to the over-the-air transmission of data to and from systems and end-user instrumentality that square measure stationary, instead of mobile. Operators of mounted wireless networks probably offer broadband services while not having to put big-ticket cable systems or affect the complexities of quality management.
Fresnel Zone is an elliptical space on either facet of the line of sight that has to even be clear for a long-range wireless network to figure.
Fringe space is that the utmost variety of a cellular system wherever cellular signals could also be weaker.
entranceway GPRS Support Node Gateway
GPRS Support Node (GGSN) may be an entrance way from a cellular network to AN informatics network that permits mobile telephone users to access the general public knowledge network (PDN) or mere personal informatics networks. The GPRS Core Network is the centralised part of the GPRS system and additionally provides support for UMTS-based 3G networks.
Ka-Band refers to the information measure of non-particulate radiation between thirty three gigacycle per second to thirty six gigacycle per second, that is largely employed in satellites in operation at thirty gigacycle per second transmission and twenty gigacycle per second downlink for mobile voice communications.
