1 7signal solution

7signal Sapphire provides you a new way to continuously and automatically measure the health and

quality of a wireless network from the user's perspective. Companies and their business processes are

becoming increasingly dependent on the performance and service quality of their wireless networks.

Thanks to the Sapphire solution, companies can integrate the quality management of wireless networks

with their existing IT and communications technology services.

7signal Sapphire uses monitoring sensors called Eyes to monitor performance and quality in WLAN

networks. It also monitors the surrounding radio frequency environment. The performance of the

customer’s network is tested against the 7signal Sonar, a test server that helps simulate client activity on

the network. Interactive tests, Eyes and parameters for automatic measurement are managed with a

centralized application called the Sapphire Carat. The measurement results are reported via an application

called the Sapphire Analyzer.

The Eye, continuously monitors the selected WLAN channels via passive listening, which does not have

an impact on network performance. It can also emulate a client device in the target network and then use

the network and the services provided through it. By analyzing the measurement results, the solution can

detect network performance and quality-of-service (QoS) issues. The solution can also produce proactive

statistics on the predicted user experience of network performance, which enables the company to

increase network capacity before the users notice a loss of performance.

In user emulation tests, also known as active tests, the Eye connects to the Sonar over the wireless

network and uses it like an ordinary production service. The usage may include mass file transfers,

browser downloads, wireless VoIP calls, or connections to another production server. Sapphire tests the

end-user experience by examining the entire data chain from the client to the production service. Active

tests can monitor the network even when there are no users in the network. This makes it possible to

forecast performance problems and take corrective actions before the service level suffers. Active tests

show the availability and quality of services offered over the network and they help administrators see why

some applications with their various demands for network performance do not work as expected in the

network or some of its areas. When problems occur, active tests can also aid to locate of the problem area

in the network topology, which often includes WLAN, LAN, and WAN elements.

The key differentiators of 7signal Sapphire are user emulation, superb coverage, continuous monitoring,

and visibility of network health. Other solutions are often based on monitoring the access point settings. As

a result, they do not give any indication of the service quality experienced by the end user. In such limited

solutions, the service quality parameters measured are the same as in wired networks. Sapphire, by

contrast, produces a comprehensive picture of the radio connection quality, where delay, number of

retransmissions, and packet loss are taken into account, in addition to other commonly measured

parameters.
