- PSTN (Public Switched Telephone Network)
|Mobility ||Mobility is not allowed|
|High-Security Issues ( As compared to wire)||Low Security Issue|
|Signal attenuation is high(Unguided)||Signal attenuation is very low(guided)|
|Low Bandwidth( As compared to wire)||HIgh Bandwidth|
Which one is good???
Before Selecting any one, we need to study some factors
- Coverage Area
- Installation and maintenance.
