which two are considered as characteristics of the original 802.11 protocol

Two key characteristics of the original 802.11 protocol were:

• 1 Mbps data rate: The very first version of 802.11 offered a maximum data rate of just 1 Mbps, which by today’s standards is very slow.
• 2.4 GHz frequency band: The original 802.11 protocol operated in the 2.4 GHz frequency band, which is also used by many other devices such as cordless phones and microwave ovens. This can lead to congestion and interference, impacting performance.

Later versions of 802.11 introduced significant improvements in data rate, frequency bands, security, and other features.
