802.11ax or WIFI6 final specifications from WIFI alliance is yet to be announced. 802.11ax access points and client devices are already in the market. 802.11ax bringing us efficiency with the help of techniques such as OFDMA by better use of spectrum, improving spatial reuse also known as BSS colouring etc. We can read a lotRead more about BSS Colouring or Spatial reuse (802.11ax AKA WiFi6)[…]
There is a lot of hype going around 5G since its announced, there is discussion going on social media whether 5G is going to impact Wi-Fi. The 5G standard promises mobile connectivity at high speed. Theoretically it can give faster and better user experience. So, I decided to write what I think about this wholeRead more about Wi-Fi vs 5G[…]
Wireshark has two filtering languages: One used when capturing packets, and one used when displaying packets. These display filters are already been shared by clear to send . It was shared as image file so I decided add different filters together and type here so people can just copy paste the filters instead having to typeRead more about Wireshark Display Filters[…]
WLAN Topologies AKA Service Sets: I would like to talk about WLAN topologies or service sets which are not difficult to but very important to understand. 802.11 defines different topologies or service sets. BSS (Basic service set) ESS (Extended service set) IBSS (Independent basic service set) MBSS (Mesh basic service set) QBSS (QOS basic serviceRead more about 802.11 Topologies AKA Service Sets[…]
I was thinking to write about the 4-way handshake and started to think that from where I should start writing. Shall I just describe 4-way handshake which can be found everywhere on the web or shall I do a deep dive? Reason for me to write is to make it easier to understand for nonRead more about 4-Way Handshake[…]
Today I would like to take the opportunity to write about inverse square law. What is inverse square law and why it’s important for us as Wi-Fi Engineers to understand. Its important to understand that how RF behaves when distance increases. I will start with light example which is easy to understand, and it workRead more about Inverse Square Law[…]
I would like to write this post specifically for beginners who are trying to understand that what is a protocol analyser or what are the options available specific to Wi-Fi troubleshooting. First question what is protocol analyser Why we need it What options are available to capture WLAN traffic How we can use it for our benefit suchRead more about Protocol Analyser for beginners[…]
Very important question that what should be the power setting of an access point. All vendors suggest that maximum transmit power is not a good idea because it increases the chances of co channel interference. During my Ekahau ECSE training by Mr Keith R. Parsons I was able to discuss this question and his answerRead more about Access Points Transmit Power[…]
You are about to learn RF maths, without having to use logarithms. The rule of 10s and 3s provides approximate values, not necessarily exact values. If you are an engineer creating a product that must confirm to RF regulatory guidelines, you will need to use logarithms to calculate the exact values. I would like toRead more about dBm to mW conversion cheat sheet[…]
