Explain the following with respect to wireless transmission:i. Two (02) types of microwave transmission techniques.ii. Advantages of radio waves

i. Two types of microwave transmission techniques:

1. Line-of-sight (LOS) microwave transmission: This technique involves the transmission of microwave signals in a straight line between two points without any obstacles in between. It requires a clear line of sight between the transmitting and receiving antennas. LOS microwave transmission is commonly used for point-to-point communication over long distances, such as in microwave links for telecommunications or satellite communication.

2. Non-line-of-sight (NLOS) microwave transmission: Unlike LOS transmission, NLOS microwave transmission does not require a clear line of sight between the transmitting and receiving antennas. It can penetrate obstacles like buildings, trees, or hills, allowing for communication in urban or hilly areas where direct line of sight is not possible. NLOS microwave transmission is commonly used for wireless local area networks (WLANs) or indoor wireless communication systems.

ii. Advantages of radio waves:

1. Wide coverage: Radio waves have the ability to cover large areas, making them suitable for long-range communication. They can be transmitted over long distances without significant loss of signal strength.

2. Penetration: Radio waves have the ability to penetrate obstacles such as walls, buildings, and foliage. This allows for communication in indoor environments or areas with obstructions.

3. Less interference: Radio waves operate in a frequency range that is less crowded compared to other wireless transmission technologies. This reduces the chances of interference from other devices or signals.

4. Cost-effective: Radio wave-based communication systems are generally more cost-effective compared to other wireless technologies. The equipment required for radio wave transmission is relatively inexpensive and widely available.

5. Easy to deploy: Radio wave-based communication systems are relatively easy to deploy and set up. They do not require extensive infrastructure or complex installation processes, making them suitable for quick deployment in various environments.

6. Versatility: Radio waves can be used for various applications, including broadcasting, mobile communication, wireless networking, and remote sensing. This versatility makes radio waves a widely used and adaptable wireless transmission technology.
