A virtual tape library (VTL) is a technology for data backup and recovery that uses tape libraries or tape drives along with their existing software for backup.The virtual tape library system emulates the former magnetic tape devices and data formats, but performs much faster data backups and recovery. It is able to avoid the data streaming...
A base transceiver station (BTS) is a piece of network equipment that facilitates wireless communication between a device and network.
A BTS consists of the following:
A network may be any wireless technology, like Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), Worldwide Interoperability for Microwave Access (WiMAX) or Wi-Fi. However, because a BTS is associated with mobile communications technologies, it refers to the equipment that creates the "cell" in a cellular network. Sometimes, an entire base station, plus its tower, are improperly referred to as a BTS or cellphone tower.
As part of a cellular network, a BTS has equipment for the encryption and decryption of communications, spectrum filtering equipment, antennas and transceivers (TRX) to name a few. A BTS typically has multiple transceivers that allow it to serve many of the cell's different frequencies and sectors.
A parent base station controller (BSC) controls all BTSs via the base station control function (BCF) - either a separate unit or integrated with the TRX for compact base stations. The BCF provides a connection to the network management system (NMS) and manages the transceiver's operational states.
The function of the BTS remains the same - no matter what type of wireless technology is used.
