as shown in the following figure: RSSI (normal value: RSSI > 30), RATE_Down, and RATE_UP (the latter two indicate
the upstream rate and downstream rate respectively).
Note: The 144.5 Mbps rate indicates that the laptop works in dual-stream mode; 72.5 Mbps and lower rates indicate that
the laptop works in single-stream mode, and the download performance is poorer.
c. More STAs slow down the downloading.
3. Key configuration
Solution 1: Dual-band dual-stream mode (applicable to high-performance deployment scenarios)
(This deployment
mode supports the dual-stream rate as well as the 2.4 GHz and 5 GHz dual-band access, and provides double throughput. In
this mode, only four rooms can be covered, all antenna ports belong to both radio card 1 and radio card 2, and one of the R1-
2, R1-3, R2-2, and R2-3 antennas must be combined with one of the R1-0, R1-1, R2-0, and R2-1 antennas.)
Scenario 1
：
FIT-AP
Ruijie(config)#ap-config xxx
Ruijie(config-ap)# ishare mode double frequency double stream
Scenario 2
：
FAT-AP
Ruijie(config)#interface Dot11radio 1/0
Ruijie(dot11-wlan-config)#antenna transmit 3
Ruijie(dot11-wlan-config)#antenna receive 3
Ruijie(dot11-wlan-config)#rate-set 11n mcs-support 15
Ruijie(dot11-wlan-config)#interface Dot11radio 2/0
Ruijie(dot11-wlan-config)#radio-type 802.11a
Ruijie(dot11-wlan-config)#antenna transmit 3
Ruijie(dot11-wlan-config)#antenna receive 3
Ruijie(dot11-wlan-config)#rate-set 11n mcs-support 15
Solution 2: Dual-band single-stream mode (applicable to scenarios with high roaming requirements but low rate)
(In
this mode, eight rooms can be covered. This mode supports the 2.4 GHz and 5 GHz dual-band access and supports only the
single-stream rate. All antenna ports belong to both radio card 1 and radio card 2. Each radio card serves eight rooms. The
load of a single radio card is heavier than that of the radio card used in other deployment modes. In addition, the attenuation
of the 5G feeder is large and the mode is basically unavailable when the feeder length is longer than 15 m. Therefore, exercise
caution when deploying this mode. The dual-band single-stream mode reduces the roaming intervals. This mode is
recommended in scenarios in which Personal Digital Assistants (PDAs) are applied frequently such as hospital wards.)
