Wireless Communication - Applications

Components and systems for mobile communication base tranceiver stations:

• in public cellular networks (e. g. GSM, UMTS, WiMAX, LTE)
  Demands are high – being reachable everywhere world-wide, fast internet access even in rural areas, or smart phones with ever higher data rates.  In the dynamic and highly competitive mobile communication market the innovative SPINNER products help providers make new network capacity available reliably, at competitive prices.

• in non-public trunked mobile wireless networks (TETRA)
  TETRA mobile communication networks are  built up nation-wide as a uniform operating wireless network for public authorities and security organisations (police, fire brigades, first aid services, military).  As internal local communication networks TETRA systems are also used by private entities (industry, local public transport, airports).

• in Railway wireless networks (analogue, GSM-R)
  Increasing cross-border railway traffic requires a uniform system for mobile voice and data communication.  Since safety-relevant signals and operating information have to be transmitted to the driver's cab there are especially high demands on the quality of the components that are used.  During the transition phase from analogue service to the GSM-R network interference-free parallel operation has to be ensured.

Components and systems for indoor coverage:

• in buildings
  A broadband passive transmission system ensures easy, reliable and maintenance-free coverage of large buildings for all desired wireless communication networks.  This avoids the expensive and unsightly installation of several antenna systems.

• in tunnels
  Tunnel radio systems support interruption-free mobile coverage when users pass through longer road or railway tunnels.
  As a co-ordination medium for relief services and an information medium for road users these systems make an important contribution to more traffic safety, e. g. in the event of accidents or fires.

• in mining
  Wireless voice and data communication in mines supports the optimum control of work processes and is a key contribution to increase operational safety.
