Mobile base station

A mobile base station, also called a base transceiver station (BTS), is a fixed radio transceiver in any mobile communication network or wide area network (WAN). The base station connects mobile devices to the network and routes them to other terminals in the network or to the core network of a mobile operator.
The network can be based on any of the wireless communication technologies like GSM, CDMA, 3G, 4G, 5G, and 6G mobile networks, WiMAX broadband, as well as wi-fi connectivity. A typical base transceiver station consists of multiple subsystems, including:
  • The baseband unit (BBU), processing all baseband signals and connecting the base station to the core network of the mobile operator via optical fiber.
  • The radio unit or remote radio unit (RRU), amplifying and transmitting the radio signals received from the BBUs to the antenna.
  • The active antenna system (AAS) introduced in the recent mobile networks (5G and beyond) to support multiple transmit and multiple receive techniques (mMIMO) based on antenna arrays.

Active Antenna System (AAS)

An active antenna system (AAS) in a mobile base station is a transceiver that integrates an antenna and radio frequency (RF) components in a single unit. This integration improves performance in mobile networks and enables some of the following advan

Key challenges

Mobile base station designers often need to manage the following aspects:

  • Compatibility for integrating base transceiver stations between different vendors' equipment.
  • Scalability in ensuring that the base station can scale to support multiple and new protocols to meet the growing demand for mobile services.
  • Energy efficiency to reduce the mobile base station carbon footprint.
  • Security, authentication, privacy, and regulatory compliance to ensure that mobile networks are secure and reliable.
