After an initial trial with 7SIGNAL's Wireless Network Monitoring platform, the IT team realized they had uncovered the right platform to guide them in their transition to a mobile-first environment. 7SIGNAL provided the historical and real-time performance visibility on network and client performance. In particular, the specific data and voice quality metrics provided the visibility the IT team was looking for to complement the information gathered from their WLAN management system.
They went ahead and deployed 25 Sapphire Eye sensors in strategic locations in three buildings at their HQ campus. With the 7SIGNAL platform in place, they could evaluate the user experience in every area of the network. The active tests provided not only a measurement of Wi-Fi performance, but also critical end-to-end visibility into DHCP responsiveness, wired network throughput and latency and http / web accessibility. The passive monitoring of the client interactions with network provided key insights into the quality of experience for each client on the network.
"The intelligence we get from Sapphire is incredible. When it comes to troubleshooting, it has removed a lot of guesswork from the equation."
The 7SIGNAL team provided assistance with the installation of the Sapphire Eye sensors, and the IT Team began using the 7SIGNAL dashboard and SLA reports to monitor performance with the visibility they had hoped to achieve. They set the SLA thresholds to match the environment and configured the system to send SNMP traps and alerts when performance of a metric such as downlink throughput fell below their desired service levels.
When they saw issues, the IT team was able to drill down to look at attach rates, retransmissions, signal levels and other metrics to isolate root cause and identify ways to improve performance. 7SIGNAL can suggest configuration changes that will likely fix the issue. Initial results showed packet loss in certain areas was too high for reliable voice services. After a series of network-wide configuration changes, they raised average MOS scores above 3.6 which gave them the confidence to safely roll out mobile voice services on VoIP handsets and softphones.
The IT management team also receives automated reports showing performance stats and trends, so they know first-hand how well the network is performing against SLAs. When changes occur in the network, such as software upgrades to networking equipment or devices, the team can use 7SIGNAL to verify the impact of those changes by comparing “before” and “after” trends. Just as important, the team is now able assess the network’s ability to handle more applications, more devices and more traffic as the company implements its mobile-first plans, allowing them to make smart, timely decisions in capacity planning.
As the transition to mobile-first fans out from headquarters to the field, 7SIGNAL will enable the company to remotely monitor and manage the performance at any location, centrally from a single platform - shortening issue resolution time and removing the need for Wi-Fi expertise in remote locations.
