| Q. | What does the G stand for in 1G, 2G, 2.5G, and 3G mobile wireless technologies? | |
| A. | It stands for generation and the use of it implies the evolutionary process that mobile wireless is going through. | |
| Q. | What are the primary reasons that service providers use a Wireless Local Loop (WLL)? | |
| A. | The primary reasons are speed of deployment, deployment where wireline technologies are not practical, and finally, for the avoidance of the local exchange carrier s network and assets. | |
| Q. | Why is digital transmission better than analog in mobile wireless technologies? | |
| A. | Digital transmissions can be reconstructed and amplified easily, thus making it a cleaner or clearer signal. Analog signals cannot be reconstructed to their original state. | |
| Q. | Why does fog and rain affect optical links so much? | |
| A. | The tiny water particles act as tiny prisms that fracture the light beam and minimize the power of the signal. | |
| Q. | What is the difference between an ad-hoc network and an infrastructure network? | |
| A. | Ad-hoc networks are a peer-to-peer group of network nodes that communicate... |
