What 1G or 2G?

In 80s, the first 1G device (the first-generation of wireless telephone technology) came out. It was called the mobile phone made by  Dr Martin Cooper.

OK, it a smartphone but it better that a answering machine 

Today, have lots of 2G network. By 1985 the was only Motorola DynaTAC, Nordic Mobile Telephone and Vodafone for the UK.

10 year later after the first 'wireless telephone'. 2G come out.

In 90s for the first time,you can go on the World Wide Web with out wire from a telephone line

It uses a Router connect to telephone. The Router sends signal to area around.

This was amazing. Most people use 2G today. The UK average is 6.2Mbps  

After the New Year, I will do a post on 3G and 4G
