Estimating Wi-Fi7 Throughput: A Theoretical Approach

Wouldn’t it be great if you can get a second order estimate of the expected throughput of Wi-Fi7 technology? This can be done even before any investment in a wireless test campaign. Wireless performance tests are expensive, time consuming and cumbersome and are necessary once you get closer to your product form factor. Think about…

Wi-Fi Trigger Frames

Wi-Fi technology is fundamentally based on listen before accessing the share medium (CSMA-CA). This was adopted for fair sharing of the unlicensed spectrum in the 2.4, 5 and 6GHz band. With the scaling in number of spatial streams and channel bandwidth, Wi-Fi technology has able to match ISP’s access network line rates 1 Gbps DOCSIS…

Multi Access Edge compute

Multi Access Edge compute (MEC) reduces network latency by bringing cloud computing and 5G network operations closer to the RAN. It is meant to support 5G’s ultra reliable and low latency (URLLC) use cases, but tests results show otherwise.Tests from Spirent Communications show that the mean latency does reduce with a public MEC but the…

Edge compute with RPI5

If you have not noticed in the hubbub of Apple’s Vision Pro grand release, in October 2023, Raspberry Pi Ltd. has launched yet another credit card-sized powerful computing platform called Raspberry 5. Yes, there have been five successful platforms before, starting back in 2012. Source: http://tinyurl.com/4nymcwrv Don’t be fooled by the size of this device.…

Make Wireless Work-WPA3

Wi-Fi Protected Access 3 (WPA3) is the latest update to Wi-Fi security supported by some Wi-Fi5 and all Wi-Fi6, Wi-Fi7 certified devices. Unlike mere version updates, WPA3 emerges after a 15-year tenure of WPA2, addressing inherent vulnerabilities well-known within the networking industry. WPA2 is vulnerable to dictionary attacks, brute force attacks, and the most famous-Key…

Can FWA/satellite disrupt the cable industry?

The cable industry giants hold a commanding position in delivering internet, telephony, and video content to the residential/B2B customer base. DOCSIS and FTTH (GPON/XGSPON) are the dominant wired technologies that can deliver data rates of up to 10 Gbps downlink speeds to residential customers. This works well for the overserved market, i.e. upgrading existing customers…

Why every home needs a Wi-Fi mesh- Statistical analysis

Recent discussions on latency management of a Wi-Fi network with an industry expert (Magnus Olden, Domos) led me to revisit my previous blog post in which I had compared latency, jitter, and packet loss data of my standalone AP with a Wi-Fi mesh system. The time domain graphs showed visual improvements in latency, jitter, and…
