7SIGNAL Sapphire Eye™ 2200


A unique Wi-Fi sensor and high-performance client

Sapphire Eye 2100 Perspective

Sapphire Eyes are robust Wi-Fi sensors and high-performance clients developed and patented by 7SIGNAL. They are uniquely designed to measure connectivity and the quality of end-user experiences on Wi-Fi networks. It complements your existing wireless access point management software by providing proactive Wi-Fi network assurance.

The 802.11ac Wave 2 Sapphire Eye 2200 utilizes 8 MIMO Yagi gain antennas (four at 2.4GHz and four at 5GHz). The antennas provide signal amplification and enable connecting to 4 to 6 access points at -65dBm or better. This ensures accurate active measurements from a single location.

Sapphire Eyes are self-contained, compact units utilizing Power over Ethernet (PoE), which allows for active Ethernet testing also. All wireless and wired communications use TLS encryption.

“In the past, I’ve had people working for six months trying to resolve problems that turned out to be the vendor’s issue. Now we have data that we can push back to the vendor with a lot more confidence.”

Tom Ogg, CIO at Akron Children’s Hospital
