Mobile phone, just for illustration (https://myupdatestudio.com)

Since first generation in 1980’s, mobile telephone has evolved from 1G to 4G, and even 5G is coming soon worldwide. The improvement from 1G to 4G is relating to transmission band, frequency band and services. 

The development of Mobile telephone is not only to its technology, but also increasing number of its users. As mentioned by Sharma (2013) that the number of mobile cellular subscribers are four times than fix telephone lines, and the trend is increasing in recent years. Thus, technology efficiency is important.  

The new generation of Cell Phone bring new technology and high data rates than the older generation (Agrawal et al, 2015). The increasing of wireless phone is following by highly requirement for better features and standard uses. 

In respect to Standards used and Features, the different of Mobile Telephones 1G, 2G, 3G and 4G are following (Agrawal et al, 2015 and Sharma. 2013): 

1G	2G	3G	4G
Advantages: 1)Analog system 2)Cordless Disadvantages: 1)Voice only, no data communication 2)Slow speed and low capacity 3)Less secure	Advantages: 1) Enhanced efficiency 2) Improved system capacity 3) Voice and data services. 4) Enhanced security Disadvantages: 1) does not support high data rates 2) Weaker digital signal. 3)Unable to handle complex data.	Advantages: 1)Supports multimedia 2)Value added services like television, GPS and video conferencing.   3)High speed internet  4) Increased capacity.  Disadvantages: 1)Expensive Cost of upgrading 3G devices  2)Power consumption is high. 3)Expensive base station	Advantages: 1)High efficiency and High voice quality. 2)Easily access internet, streaming media etc 3)Simple protocol architecture. 4)Efficient multicast/broadcast. Disadvantages: 1)Higher data prices  2)very expensive and hard to implement 3)Complex hardware. 4)Power usage is more.
