Unique Wi-Fi Performance Sensors

Sapphire Eyes are advanced WLAN sensors created and patented by 7signal. They are purposely created to measure connectivity and the quality of the end-user experience on business WLANs. Sapphire Eyes include powerful directional sector antennas and act as a high performance client device on the Wi-Fi network, repeatedly testing Wi-Fi performance when connected through the APs deployed in their vicinity.

The Eyes complement your current wireless access point management software, which enables proactive WLAN assurance. The image to the right is the Sapphire Eye 2100 indoor sensor which supports 802.11ac. Due to its slim profile you are able to easily conceal it within any location.

The video below shows founder and CTO, Veli-Pekka Ketonen, taking a closer look at the larger, outdoor sensor, the Sapphire Eye 1000.

What Eyes See and Do

Sapphire Eyes execute active, cyclic end-user synthetic test traffic (Layers 1-7), provide a comprehensive passive analysis (Layers 1-2) as well as 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 analysed within the Eye and the results are stored in a cloud database which is part of the Sapphire Cloud analytics 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
  • Utilization

Sapphire Eyes are generally mounted throughout the WLAN area. Each Eye utilizes a dual-band 802.11 radio with beam steering and low noise RF amplification technologies to maximize the range of operation and enable active tests. Depending on your environment, Eyes are able to cover between 4 and 8 wireless access points. Sapphire Eyes take power from Power over Ethernet (PoE) and their wireless communications are encrypted.

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