A telecommunications engineer is designing a Wi-Fi network that will use either a 2.4 GHz or 5 GHz signal in a client's local area network.
How do the 2.4 GHz and 5 GHz signals differ in performance? (2 marks)
--- 6 WORK AREA LINES (style=lined) ---
→ 2.4 and 5 GHz signals differ in bandwidth, data transfer rate and attenuation (loss of signal strength).
→ A 2.4 GHz signal carries less data per second but suffers from less attenuation than a 5GHz signal.
→ 2.4GHz signals can also be transmitted through more/thicker obstacles.
