Title: (EN) ACTIVE ANTENNA DEVICE, NETWORK DEVICE AND ACCESS POINT OF A WIRELESS NETWORK
Abstract: front page image
(EN)

An active antenna device, a network device, an access point equipped with the network device and a plurality of distributed active antenna devices form components of a communication system. The active antenna device contains an antenna unit, an amplifier unit and a control unit, wherein the amplification of the amplifier unit is controlled by the control unit according to an instruction from a management unit located in the network device. The devices achieve a low handover frequency whereas rendering the communication less vulnerable to contentions and/or interference than in the conventional systems.
