Terrestrial Trunked Radio (TETRA; formerly known as Trans-European Trunked Radio), a European standard for a trunked radio system, is a professional mobile radio and two-way transceiver specification. TETRA was specifically designed for use by government agencies, emergency services, (police forces, fire departments, ambulance) for public safety networks, rail transport staff for train radios, transport services and the military.
Digital Enhanced Cordless Telecommunications (Digital European Cordless Telecommunications), usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems. It originated in Europe, where it is the universal standard, replacing earlier cordless phone standards, such as 900 MHz CT1and CT2.
Bluetooth® technology proves the power of connection. Nearly 4 billion devices will ship this year using Bluetooth to connect. To phones, to tablets, to PCs, or to each other.
And Bluetooth enables multiple ways to connect. After first demonstrating the power of simple point-to-point connections, Bluetooth broadcasting is now powering the global beacon revolution and accelerating new markets—like smart buildings—through mesh connections.
Long Term Evolution (LTE) is a mobile network technology that is being deployed by mobile operators on both the GSM and the CDMA technology paths. Depending on the spectrum available, live LTE networks can deliver very fast data speeds of up to 100Mbps in the downlink and 50Mbps in the uplink.
Designed to be backwards-compatible with GSM and HSPA, LTE incorporates Multiple In Multiple Out (MIMO) technology, the Orthogonal Frequency Division Multiple Access (OFDMA) air interface in the downlink and Single Carrier FDMA in the uplink. This combination provides high levels of spectral efficiency and network performance, coupled with high network capacity and low latency. LTE will support spectrum channel bandwidths from 1.4 MHz to 20 MHz and can operate in both paired spectrum (in FDD mode) and unpaired spectrum (in TDD mode).
