A method and a system ( 100 ) for transmission of a large amount of data over a first dedicated wireless link (A) at a first frequency, such as 2.4 GHz. If the signal strength is weak, the data is further compressed. If the signal strength is further weaker, a second wireless link (B) is used at a second frequency, such as 868 MHZ. The second wireless link (B) is at the same time used as a network system for exchange of information in which the nodes of the system operates as nodes in a multi-hop system. |
