Best Wireless Technologies for 5GHz Frequency in Small Office

A network technician is installing a new wireless network in a small office.

Due to environmental concerns, the customer wants the network to run exclusively on the 5GHz frequency.

Which of the following wireless technologies should the technician install to BEST meet this requirement? (Choose two.)

A.

802.11ac

B.

802.11b

C.

802.11g

D.

802.11n

E.

Bluetooth

F.

Z-Wave.

AD.

To meet the requirement of running the wireless network exclusively on the 5GHz frequency, the network technician should choose wireless technologies that support this frequency band.

The 5GHz frequency band offers higher throughput and less interference than the 2.4GHz band. Therefore, it is suitable for applications that require high bandwidth and low latency, such as streaming video and online gaming.

Out of the given options, the following two wireless technologies support the 5GHz frequency band:

A. 802.11ac: This wireless technology supports both the 2.4GHz and 5GHz frequency bands. It is the latest and fastest standard for wireless networks, offering speeds of up to 6.9 Gbps. It uses multiple antennas to provide better coverage and reliability, making it ideal for high-density environments such as offices, schools, and airports.

D. 802.11n: This wireless technology also supports both the 2.4GHz and 5GHz frequency bands. It offers speeds of up to 600 Mbps and uses multiple antennas to improve coverage and reduce dead spots. It is suitable for small to medium-sized businesses that require a reliable and fast wireless network.

B, C, E, and F do not support the 5GHz frequency band.

B. 802.11b: This wireless technology operates on the 2.4GHz frequency band only. It is an older and slower standard, offering speeds of up to 11 Mbps.

C. 802.11g: This wireless technology also operates on the 2.4GHz frequency band only. It offers speeds of up to 54 Mbps and is compatible with older devices that do not support the 5GHz band.

E. Bluetooth: This is a short-range wireless technology that operates on the 2.4GHz frequency band. It is commonly used for connecting peripherals such as keyboards, mice, and headphones.

F. Z-Wave: This is a low-power wireless technology used for home automation and IoT devices. It operates on the 908.42 MHz frequency band in North America and 868.42 MHz in Europe.

In summary, the best wireless technologies to meet the customer's requirement for a wireless network operating exclusively on the 5GHz frequency band are 802.11ac and 802.11n.
