Overview

A novel WiFi performance testing technology that uses less bandwidth, improves the speed of testing, and allows for continuous performance testing.

Technology Summary

WiFi performance is important in providing an optimal experience for mobile device users. WiFi performance tests can be used to measure the speed of one’s network connection. These tests are expensive in terms of time, bandwidth, and data usage. A new technology, Fast Mobile Network Characterization (FMNC) is being developed to improve these metrics. FMNC uses clever packet sequences and awareness of frame aggregation to rapidly characterize available bandwidth. It uses 250 times less bandwidth than the competition. FMNC data usage is 0.1MB per test, while competitors use 4.4-10MB

FMNC improves upon existing solutions in two ways. First, it uses 250 times less bandwidth than the competition. FMNC data usage is 0.1MB per test, while competitors use 4.4-10MB. This enables continuous background testing that does not use large amounts of network data. Second, FMNC can characterize available bandwidth in under .250ms, which means that the WiFi speed test results are delivered faster and are more accurate (bandwidth can vary widely during the course of a speed test.) This solution could provide effortless background testing on mobile devices, resulting in more data points for network performance monitoring companies.

Market Advantages 

  • Data Savings over competition
  • No changes should be required to the client or network infrastructure
  • Can be used to test via a mobile application or via hardware endpoints placed inside a building for continuous feedback
  • Provides an accurate performance test for users, whose data can be used to deliver WiFi performance analysis across the network
