The use of 1.4GHz radio systems gives network operators a number of key benefits:-
Longe range - This will become increasingly important in developed countries as all the best cell sites have been taken and future mobile coverage will require more innovative solutions. Growth in systems such as TETRA, and GSM-R require higher range as they have to work in remote areas.
Reliable operation over difficult terrain - This is becoming more of an issue even in developed countries as coverage for emergency services is expanded, and planning issues for complex towers and antennas become more difficult to resolve. In more rural overseas territories, expansion of rural telecoms, control of infrastructure and growth in mobile communications in previously remote areas all points towards the need for cost effective radio solutions able to cope with atmospherics conditions (monsoons, sandstorms, dense vegetation etc).
Simple and low cost installation - Using simple flat panel or YAGI antennas the installation of 1.4GHz systems is quick and easy. Rental costs for tower installations are lower as the antennas are small and compact. All indoor design means that maintenance can be carried out without specialist climbing teams.
