Chapter 1

Why is the direct sequence spread spectrum modulation technique ideal fordata communications?

1. It spreads a transmission signal over a narrow range of radio

frequencies so there is minimal loss.2. It splits the radio signal into multiple smaller sub-signals that are

transmitted at different frequencies to achieve high throughput.

3. It is less susceptible to radio noise and creates little interference.

4. It reduces interference because it is only affected if two signals are

transmitting at the same frequency at the same time.

Chapter 1

Why is microwave a less desirable solution than radio wave transmission inwireless bridge applications? (Select four.)

1. Equipment cost is typically high.

2. A government license is usually required.3. Transmission rates are unreliable in any weather.

4. Rain, fog, or snow can significantly reduce performance.

5. The network is very difficult to maintain.
