What is the difference between 3G and 4G as in their speed and their technologies.

3g is current technology which help us to access internet from mobile platform with speed up to around 7mb max and 4g is future but in county like Norway has already implemented the 4G in OSLO. 4g has access speed up too 100 mb in theory but real world benchmark can be vary due to infrastructure.

4G is faster when dealing with internet than 3G. You'll be able to load web pages and download things faster.

Representing the third and fourth generations of mobile technology respectively, 3G and 4G networks have many differences. Most notably, their rates of data transfer and signal quality are highly divergent. However, the implementation of 4G networks has faced many hurdles. Unlike 3G, 4G technology is not fully defined by governing bodies in charge of wireless technology.
3G and 4G networks offer divergent levels of data transfer from sources to a device. According to the International Telecommunication Union (ITU), 3G provides 14 megabits per second (Mbit/s) download and 5.8 Mbit/s upload. This is compared to the projected minimum 100 Mbit/s transfer speed of 4G.
According to the ITU, 3.9G networks use a form of antenna system known as spatial multiplexing. Using the smart antenna features from 3G technology, 3.9G deploys a number of these antenna both to transmit and to receive, allowing for a better signal.
The ITU standardized 3G networks for use with both circuit- and packet-based networks, meaning the data is transferred both through wired and wireless networks. 4G is set up to use the packet technology only, being the first generation of technology to be completely wireless.
