Generating a network map

摘要: Aspects of the present invention relate to a method, and various systems operable or arranged to implement that method, of generating a network map illustrating availability of network access technologies in various locations of the network. The method may comprise the following steps:(a) sending, by a first network unit, the location of which is identified by a first identifier, first data to a second network unit, the location of which is identified by a second identifier, whereby the first data is sent using at least two different network access technologies and is sent to at least two different possible locations for the second network unit;(b) receiving by the first network unit from the second network unit, first measurement data relating to the sent first data; and (c) generating the network map based on the measurement data, the first identifier and the second identifier.
