Industry:Technology
Speech recognition systems interpret human speech and translate it into text or commands. Primary applications are self-service and call routing for contact center applications; converting speech to text for desktop text entry, form filling or voice mail transcription; and user interface control and content navigation for use on mobile devices, PCs and in-car systems. Control of consumer appliances (such as TVs) and toys is also commercially available but not widely used.
Industry:Technology
A circuit designed for the transmission of speech, either analog or encoded, but which can also be used for data transmission or telegraphy.
Industry:Technology
A global effort under the auspices of the ITU to encourage governments and regulators to allocate RF spectrum consistently across borders, thereby enabling global roaming, interoperability and global markets for telecom equipment. Every four years, the ITU holds the World Radiocommunication Conference, where global/regional spectrum assignments are negotiated and agreed. A recent example is the 1.9GHz to 2.1GHz band, which has been allocated to UMTS in almost every geography. The WiMAX Forum is undertaking similar efforts to support global allocation of 2.5GHz and 3.5GHz for wireless broadband.
Industry:Technology
A continuous range of frequencies, usually wide in extent, within which waves have some specific common characteristics.
Industry:Technology
The four stages on which essential activities in the successful deployment of advanced technology are based. They are:
• Specification — which aligns corporate strategy and technology focus
• Tracking — which assesses individual technologies for maturity and business impact
• Evaluation — which involves prototyping and other in-depth evaluation activities to further gauge the readiness and relevance of the technology
• Production — which sees the technology being piloted and, if successful, rolled out into full deployment.
Industry:Technology
A wireless communications technology in competition with analog cellular services. In an SMR system, the base station equipment supplier is the licensee of the transmitters. Users have access to the multiple channels of the network rather than the limited number of channels of a private mobile radio network. Many users share all of the available channels. Sharing is accomplished on a first-come, first-served basis. When users want to initiate a call, they activate the push-to-talk button on the handset. Assuming the portable unit (and dispatcher or other portable unit) is tuned to an available channel, a communication path is established. If channels that the sender and receiver can use are not available, the call cannot be completed, and the operator must wait for another opportunity to try again.
Industry:Technology
Advanced multiple antenna technique that increases the spectral efficiency, range and bandwidth available to moving wireless devices. Traditional cellular base stations radiate power in all directions, because they have no information about where the mobile device is located. This wastes power and causes interference to adjacent cells, as well as making it harder to distinguish weaker incoming signals from among the noise and interference. By using smart antenna technology to track the spatial location of mobile devices, the radiation pattern of the base station can be adjusted to optimize both transmission and reception for each user device. By rapidly adjusting the phase of signals from several antennas, the base station can effectively steer a beam or a spot of RF power to or from each user. Unlike MIMO, only one antenna is required at the client device, potentially reducing customer premises equipment (CPE) costs. SDMA techniques are used in proprietary wireless broadband systems and are likely options for mobile WiMAX and LTE. See also smart antenna.
