They have two frequencies for different reasons. 
1800 was added due to congestion on 900. In 
North America 850Mhz is longer distance due 
to higher output power. Read specs on cellular 
modules (hardware) and you will see  850Mhz 
is higher output power. That is why it is used 
more often in rural areas. It can be hundreds 
of miles between cities over here.
