Question 76
Because 802.11a supports the same maximum rate as 802.11g supports, the 802.11a protocol is backward compatible with the 802.11g protocol.
Question 77
The number of users is 300, and the concurrency rate is 70%. The terminal supports the 2.4 GHz and 5 GHz frequency bands. According to the maximum number of users per dual-band dual-frequency AP, at least APs can meet the capacity requirements.
Question 78
If the coverage area has a higher demand on WLAN capacity, it should consider the construction mode of ().
Question 79
Choice of WLAN covering antenna, for long and narrow area, we suggest (); for open and short area, we suggest ().
Question 80
If the forwarding mode of an enterprise wireless network is direct forwarding, the Fit AP can convert the 802.11 data packet into an Ethernet packet, and then encapsulate the packet into a CAPWAP encapsulation and transmit the data packet to the AC through the CAPWAP tunnel.
