Word Definition
vCARD
vCARD is a standard defining the format of an electronic business card. All devices supporting vCard can exchange information such as phone numbers and addresses. For instance, a user with a vCard-aware phonebook application on a handheld computer can easily transfer names and phone numbers to a vCard-aware mobile phone.
VHF: Very High Frequency
Very High Frequency (VHF) is the RF spectrum between 30 MHz and 300 MHz.
Viterbi algorithm
Viterbi algorithm is a technique for searching a decoding trellis to yield a path with the smallest distance. This is also known as maximum likelihood decoding.
VLR: Visitor Location Register
Visitor Location Register (VLR) contains all subscriber data required for call handling and mobility management for mobile subscribers currently located in the area controlled by the VLR. The VLR communicates with the HLR of the subscriber to request data about that subscriber.
VMAC: Virtual Media Access Control
Virtual Media Access Control (Virtual MAC or VMAC) is an algorithm that passively monitors the radio channel and estimates locally achievable service levels. The VMAC estimates key MAC level statistics related to service quality such as delay, delay variation, packet collision, and packet loss.
Vocoder
Vocoder refers to a voice encoder which is a device that codes and decodes the human voice (sound waves) into digital transmission. Higher vocoder speeds offer enhanced sound quality.
Voice Activated Dialing
Voice Activated Dialing is a feature that permits you to dial a phone number by speaking it to your wireless phone instead of punching it in yourself. The feature contributes to convenience as well as driving safety.
Voice Channel
Voice Channel is a channel used for transmission of voice data from a base station to a cellular phone (forward voice channel) or from a cellular phone to a base station (reverse voice channel).
oWIP: Voice over Wireless IP
Voice over Wireless IP (VoWIP) is the combination of VoIP with 802.11 wireless LANs to create a wireless telephone system. VoWIP enables businesses to leverage their wireless LANs to add voice communications, enabling companies to deploy and manage voice and data over a single wireless backbone. VoWIP applications require some reservation of bandwidth to support the real-time nature of voice. Proprietary standards like Spectralink Voice Priority (SVP) are today's solution; however, the IEEE is developing the 802.11e standard for quality of service as a long-term solution.
VoxML: Voice Markup Language
Voice Markup Language (VoxML) is a technology from Motorola for creating a voice dialog with a Web site in which a user can call a Web site by phone and interact with it through speech recognition and Web site responses.
