Sapphire Eye Wi-Fi performance sensors

Sapphire Eyes are state-of-the-art WLAN sensors developed and patented by 7signal. They are uniquely designed to measure connectivity and the quality of the end-user experience on business WLANs. The Sapphire Eye 2100 contains a powerful directional sector antenna board and acts as a high performance client device on the Wi-Fi network, continuously testing Wi-Fi performance when connected through the APs deployed in their vicinity.

They complement your existing wireless access point management software, enabling proactive WLAN assurance. View a full list of capabilities. Pictured above is the Sapphire Eye 2100  which supports 802.11ac and between 4 and 8 access points. Its slim profile makes it easy to conceal in your environment.

Below is the Sapphire Eye 500, a smaller version of the 2100 that connects to 1 or 2 access points. It 5x5x2 inches, but don’t let the small size fool you. It has all the capabilities of it’s bigger 2100 brother.

What Sapphire Eyes See and Do

Sapphire Eyes execute active, cyclic end-user synthetic test traffic (Layers 1-7), perform a comprehensive passive analysis (Layers 1-2) as well as 2.4GHz and 5GHz spectrum analysis. The tests are defined in a custom automated test profile which can include communication with premises and cloud servers of unique importance to your business. WLAN data is analyzed within the Eye and the results are stored in the EyeQ Cloud database which is part of the EyeQ Cloud platform. These are a few of the 600 key performance indicators that can be measured and tracked around the clock.

  • Throughput
  • Packet loss
  • Latency
  • Jitter
  • Voice quality
  • Success rates
  • Retry rates
  • Airtime utilization

Sapphire Eyes are typically ceiling mounted throughout the WLAN area. Each Eye utilizes a dual-band 802.11 radio and low noise RF amplification technologies to enable active tests and maximize the range of operation. Sapphire Eyes take power from Power over Ethernet (PoE) and their wireless communications are encrypted.

On the 2100 model, beam steering provides amplification in the target direction and suppresses interference from other directions. This enables Eyes to make accurate active measurements from one single location. The use of client end beam steering technology essentially creates virtual test points in each beam direction.
