Evaluation Of Wireless Signals :
- 1.Analog signal :
1G Technology: It is the first generation of wireless mobile communication where analog signals are used to transmit data. it was introduced in the US in early 1980 to designed exclusively in voice communication. Analog the signal is totally based on the 1G signal. it is used for communication but analog signal has less penetration level and it is highly exposed to noise area there is why the 1G system is limited for a certain area
Benefits Of Analog Signal :
- Speed is up to 2.4 kbps
- Large phone with limited battery
- Can connect with other person located at any where in the world.
Limitations Of Analog Signal :
- No data security
- Poor voice quality
- 1G is Only Used For Voice Calling , It can't be used to surf internet.
