History of mobile communication

1921:- Personnel of theDetroit Police Department radio bureaubegan experimentation with a band near 2 MHz for vehicular mobile service. the department commenced regular one-way radio communication with its patron cars.

Two-way police radio became standard throughout the country following the success of the baryon ne initiative.

1940:- New frequencies allocated between 30-40 MHz leads to substantial buildup of police radio systems.a major advance in police radio occurred when the Connecticut State Police began operating a two-way, frequency modulated system in Hartford. The statewide system developed by Daniel E. noble of the University of Connecticut and engineers at the Fred M. Line Company greatly reduced static, the main problem of the amplitude modulated system. Fm mobile radio became standard throughout the country following the success of the Connecticut initiative.

The first pre-commercial demonstration network in the southern hemisphere was built inAdelaide, south, Australia by m.Net Corporation in February 2002 using umts on 2100MHz. This was a demonstration network for the 2002 IT World Congress. The first commercial 3G network was launched by Hutchison Telecommunications branded asThreein March 2003.

In December 2007to 190 3G networks were operating in 40 countries and 154HSDPA networks were operating in 71 countries according to the Global Mobile Suppliers Association. In Asia, Europe Canada and the USA telecommunication companies use technology with the support of around 100 terminal designs to operate 3G mobile networks.

The nomenclature of the generations generally refers to a change in the fundamental nature of the service. The first was the move from analogue 1g to digital2g transmission. This was followed by multi-media support,spread spectra rum scissions and at least 200kbit/s 3g and now 4g which refers to allippacket switched networks, mobile ultra-broadband (gigabit speed) access andmulticarrier transmission.
