Channel spacing IEEE 802.11a: 20MHz
IEEE 802.11b/g: 5MHz
IEEE 802.11n at 2.4 GHz: 5MHz
IEEE 802.11n at 5 GHz: 20MHz
Wireless baud rate IEEE 802.11a: 6 to 54 Mbps
IEEE 802.11b: 1to11 Mbps
IEEE 802.11g: 6 to 54 Mbps
IEEE 802.11n (at both 2.4GHz and 5GHz): 6.5 to 72.2
Mbps
Data latency Total delay of data transmission from the monitor to the
CMS: ≤ 2s.
Delay of configuration settings transmission from CMS
to Accutorr 7: ≤ 2s
Roaming Network switchover is automatically executed when the
Accutorr 7 moves from the coverage area of AP1 to that
of AP2.
System capacity Number of the Accutorr 7 supported by a single AP is ≤
16. Each Accutorr 7 can communicate with the CMS.
Data security Security standards: WPA-PSK , WPA2-PSK, WPA-
Enterprise/WPA2-Enterprise
EAP methods: PEAP-MsCHAPv2, PEAP-GTC, PEAP-TLS,
EAP-TTLS, EAP-TLS, EAP-FAST, and EAP-LEAP
Encryption modes: TKIP and AES
Resistance to wireless
interference The wireless functions of Accutorr 7 are normal when
the following conditions exist simultaneously:
The distance between interfering devices (including
wireless devices at the frequency of 2.4GHz such as
cellular communication devices, microwave ovens,
intercoms, cordless phones and electro-surgical units,
excluding Wi-Fi) and the monitor is greater than 20 cm
.
Co-channel interference (CCI) on the Wi-Fi network
should be no greater than -85dBm.
Adjacent–channel interference (ACI) on the Wi-Fi
network should be no greater than -50dBm.
Dynamic networking stability The Accutorr 7 meets its functional requirements when
it moves at a rate of no more than 3.75 m/s within a 15
m non-blocking linear distance.
Network interruption alarm When a network interruption occurs, the equipment
shows a disconnection icon on the screen and presents
the related alarms.
When the network interruption is resolved, wireless
connection recovers automatically.
