Problems solved by technology

For communication systems using narrow beam antennas, it is very difficult to support communication under non-line-of-sight conditions
Also, in a communication system using narrow beam antennas on both sides, the replacement of a broken link is very time consuming because a new suitable communication path must be searched for
This results in a significantly reduced data transfer rate

Embodiment Construction

[0107] Below, refer to figure 1 A preferred embodiment of the communication system of the present invention is described.

[0108] The communication system 0 includes: a first station 1 including three first narrow beam antennas 31 , 32 , 33 ; and a second station 2 including three second narrow beam antennas 41 , 42 , 43 .

[0109] In this embodiment, the first and second narrow beam antennas 31, 32, 33, 41, 42, 43 are smart antennas.

[0110] The first and second stations 1, 2 are adapted to establish at least one first communication path 7a and another communication path 7b, 7c for simultaneously via said first and second narrow beam antennas 31, 32, 33, 41 , 42, 43 for wireless communication.

[0111] The further communication path 7b, 7c is spatially different from the first communication path 7a.

[0112] Therefore, according to the invention, it is proposed to use multiple pairs of narrow (sharp) beam antennas 31, 32, 33, 41, 42, 43 on both the transmitting and recei...

Abstract

The present patent application is directed to a communication system 0 comprising a first station 1 with a first narrow beam antenna 31 and a second station 2 comprising a second narrow beam antenna 41, wherein the first and second stations 1, 2 are adapted to establish a first communication path 7a for wireless communication via said first and second narrow beam antennas 31, 41, respectively. It is a disadvantage with such a communication system that communication via said first communication path might be disturbed by randomly appearing obstacles. In consequence, the data transmission rate is reduced. According to the present invention said first and second stations 1, 2 are adapted to automatically establish at least one alternative communication path 7b, 7c for wireless communication via said first and second narrow beam antennas 31, 41, said alternative communication path 7b, 7c being spatially different from said first communication path 7a.

Description

technical field [0001] The invention relates to a communication system comprising the features of the preamble of independent claim 1 . Furthermore, the invention relates to a corresponding communication method. Background technique [0002] Wireless communications are used in a wide variety of technical fields. Common examples are mobile phones, wireless LANs, walkie-talkies, radio systems, and point-to-point radio systems. [0003] The communication radius covered by the respective communication system essentially depends on the technology used. Whereas GSM and UMTS are suitable for communication radii of up to about 10 km, wireless LANs are often limited to about 100 m, and Bluetooth systems are usually limited to about 20 m. The main influence on the communication range of communication technology is the transmission frequency and output power used. However, the transmission frequency used by GSM / UMTS only has a small amount of absorption of electromagnetic waves in ...
