摘要
An apparatus that is employed to increase the data transfer capacity between transmitters and receivers for short-range data communication, particularly for the ISM frequency bands where different transmitters with different modulation and transmission methods operate in the same frequency band. The object is achieved by orienting antenna lobes that provide high antenna amplification towards transmitters and receivers in the local area of the apparatus, with the result that the distance loss between a transmitter and receiver becomes less than the distance loss represented by the lobes oriented away from the apparatus and the inbuilt amplification in the apparatus. In contrast to a normal "repeater" function for increasing a coverage area, the object is particularly achieved of increasing the capacity in an area where there is already a good transmission channel between transmitters and receivers. The various transmitters and receivers are divided into sub-networks that are isolated from one another, and where the connection is broken between transmitters and receivers that do not communicate with one another. By doing this on the physical level, one is independent of a chosen modulation method and transmission protocol. Thus the invention is especially suitable with the ISM frequency band where a countless number of known and unknown modulation methods and protocols may exist.
