WiFi6 access point and IoT test boost
OctoScope doubles the number of virtual stations supported in its Pal-6 and Stack-Max WiFi6 testbeds for the Internet of Things (IoT)

Test equipment developer octoScope has doubled the virtual station testing capacity in all of its WiFi6 testbeds.

The latest WiFi6 technology emphasizes usage scenarios with hundreds or thousands of devices connecting simultaneously in high density venues such as stadiums, factories, warehouses and office buildings. Similarly, in the home, applications such as Internet of Things (IoT) increases the number of Wi-Fi devices needing simultaneous connectivity.

The latest WiFi test equipment is required to verify performance in usage scenarios with hundreds of devices per access point (AP). Scaling test systems to supporting hundreds of Wi-Fi radios has limits using conventional technologies as issues arise about the size, cost and heat dissipation of the test system. A useful alternative is to use virtual stations. 

octoScope now supports 64 virtual stations, vSTAs, per radio in its Wi-Fi instrument, Pal-6. The total number of vSTAs per Pal-6 has doubled from 96 to 192. octoScope’s STACK-MAX testbed with four built-in Pal-6 instruments now supports 768 virtual stations to support important test cases for enterprise APs or consumer IoT scenarios.  

Each vSTA acts as an independent TCP/UDP/ICMP/IP traffic endpoint enabling testing on a mass scale with a variety of independent controllable traffic streams.

“Given the focus in high density networks with WiFi6, this is an important breakthrough that helps our customers test scenarios where performance is required with hundreds of connected devices,” said Janne Linkola, octoScope’s Senior Director of Marketing.

Stackable and configurable octoBox personal testbeds are completely isolated from external interference and can be used at an engineer’s office or lab bench.

Each octoBox testbed is controlled by a dedicated Node.js web server accessible via a browser UI for manual control, or via REST API for test automation. The server provides the time base for the testbed and controls the built-in instruments, DUT configuration, traffic, and test flow. Test results are saved in a MongoDB database, enabling multiple teams to easily collaborate by sharing the test automation scripts and
