1. Why is electromagnetic waves is a crucial part of this technology?
2. What is the objective of the RF wireless technology?
3. What are the benefits and limitations of this technology
4. Include numerical info relevant to RF wireless technology
What extend does it reduces waves, what frequencies are sensed, cost, weight, size...
5. Describe another technology that accomplishes the same objective in a different manor
RF = Radio Frequency
I know it's long but thanks for answering!!!

1. Radio frequency (RF) waves are electromagnetic. That is their very nature.
2. To eliminate wires and make using various devices easier, more convenient and practical.
3. Benefits: It makes using devices easier and more convenient. Limitations: Signals can be disrupted by interference; less secure than wired systems; usually limited to short distances.
4. WiFi, the wireless system used for computer networks, uses frequencies in the 2.4 GHz range. The rest of this question is far too complex to answer here.
5. Wired systems can offer the same features as wireless systems, only with wires. Optical (such as infrared devices) also can do what wireless RF devices do.
