Like all new devices it took time to roll the new system out but it was in fairly widespread use amongst the Allies by the end of the war. More advanced versions of the Fullerphone system were in extensive use in World War Two.
Wireless Wars
In 1914 the use of wireless was largely restricted to large relatively permanent land installations and ships. The inhibiting factor was both the lack of portability of the equipment itself (particularly the receiving units) and the size of aerial needed to have any sort of effective range. By the end of 1918 wireless sets were in use in the front line, in tanks on wireless trucks, from aircraft and even motorcycle mounted. Right from the beginning wireless played an important strategic role. Germany anticipated the possible loss of its submarine cables if war broke out and invested heavily in installing powerful wireless stations in all its colonies, even the smallest. German commercial companies were ‘encouraged’ to set up subsidiaries with large transmitters and receivers in countries that were likely to be neutral. The United States was the principal country in which this was done and Telefunken established a number of stations there (they also supplied the US Army with wireless equipment).
