802.11b D.
802.11n.
D.
A company wants to implement a wireless infrastructure on its campus to meet the needs of its BYOD initiative.
The company has users with legacy devices and wants to accommodate them while delivering speed to other users who have modern systems.
Which of the following standards BEST fits these requirements?
A.
802.11a

802.11ac

802.11n.
D.
The answer to the question is D, 802.11n.
802.11 is the family of wireless networking standards created by the Institute of Electrical and Electronics Engineers (IEEE). Each standard within this family uses different frequencies and encoding methods to transmit data over the air.
802.11n is a Wi-Fi standard that was released in 2009. It operates on both the 2.4 GHz and 5 GHz frequency bands and provides increased speeds and improved range over previous standards, such as 802.11a, 802.11b, and 802.11g.
802.11n uses multiple antennas and MIMO (Multiple Input Multiple Output) technology, which allows it to transmit and receive multiple data streams simultaneously. This results in higher data rates and improved signal quality, which is particularly useful in environments with multiple wireless devices.
In the scenario given, the company has users with legacy devices, which may not support the latest Wi-Fi standards. 802.11n is backward compatible, meaning that it can support legacy devices while also providing higher speeds to modern systems. This makes it the best option for accommodating the needs of both types of users.
802.11a operates on the 5 GHz frequency band and provides high data rates, but it is not backward compatible with legacy devices that only support 802.11b or 802.11g.
802.11ac is the latest Wi-Fi standard, released in 2013. It operates on the 5 GHz frequency band and provides even higher speeds than 802.11n, but it may not be necessary for the company's needs and could be more expensive to implement.
802.11b operates on the 2.4 GHz frequency band and is the oldest Wi-Fi standard. It provides lower data rates than 802.11n and may not be sufficient for the company's needs.
In summary, 802.11n is the best option for a company that wants to implement a wireless infrastructure on its campus to meet the needs of its BYOD initiative while accommodating legacy devices and delivering speed to modern systems.
