7signal Sapphire Deployment Guide Release 3.0
To test and use the wireless connection the following variables must be known:
ESSID – test parameter to connect to a particular wireless network.
Wlan encryption – The encryption is “Wireless Network” related configuration in
Carat.
Network keys – pre-shared keys, certificates or similar - are stored in Eye file system by Carat
application.
To be observerd:
the target wireless network may be configured to have MAC address
preventions so the MAC address of wlan interface of the Eye unit must be white-listed as a
network client. Eye does not act as an access point of the wireless network.
Security:
while the connection is established, the test parameters and results go unencrypted
over 7signal proprietary protocol encapsulated in well-formed http between the endpoints. It
is difficult to imagine that the test parameters and pseudo-data would pose any business risk
to customers. Furthermore, by default there is no encryption in the IP traffic of the wireless
clients so in this sense the current state reflects the real-world well.
MOS test connections
MOS test is a license-controlled feature and not used in every environment. MOS test requires
additional ports to be used. MOS traffic is special-purpose traffic with identical fingerprint than
any VoWLAN call would have.
Sonar may serve numerous Eyes concurrently and therefore provides numerous open server
socket s for incoming VoIP calls. One server socket may serve one Eye at a time so the number
of concurrent MOS tests in single Sonar is dictated by the number of open ports.
Eye has one open server socket for VoIP calls as it communicates with single Sonar only at a
time.
