I started my CWNE journey in 2013 when I first passed my CWNA exam. It indeed took a long time before I ticked all the boxes and started writing my blogs and complete all my assignments in 2017. It is always motivating when you get to know a CWNE and talk to them about their … More CWNE #255 -A journey not to forget

I have put down my thoughts on wireless site survey and its best practices. Wireless site survey is a debatable activity as there is “no my way or your way”. As long as you have achieved success with planning, design and optimising you have done it the right way. Having said that, each engineer may … More Wireless site survey best practices

This model of wireless anchoring may not be a very common practice in enterprise networks. This solution has its use case in public sectors and very common in educational and healthcare organisations where people share building spaces and Network infrastructure. This solution shows how universities and healthcare organisations can deploy this model of wireless anchoring which … More Wireless anchoring with partner organisations

There are 3 types of frames used in the 802.11 layer 2 communications happening over the air which manages and controls the wireless link. Management Frames Control Frames Data Frames In this blog we will have a detailed look at all the management frame packet captures. Management Frames: Management frames are used by stations to … More Understanding 802.11 Management Frames

An access point acts as hub between station(client device) and other devices on the network. Before the station can send traffic through an access point, it must have established a connection state. There are three 802.11 connection states: State 1: Unauthenticated and Unassociated State 2: Authenticated, Unassociated State 3: Authenticated, Associated The station must be … More 802.11 Association process

I wanted to compare the throughput of Cisco 2802i and Cisco 3802i access points so that I can get some realistic stats on their performance. Below report from Miercom is a good reference. https://www.cisco.com/c/dam/en/us/solutions/collateral/enterprise-networks/802-11ac-solution/miercom-report-cisco-aruba-wave.pdf Below are the comparison charts for these 2 access points. Test switches : Cisco Mig 3850 switch and Cisco 3850 U-poe … More Throughput testing between Cisco 2802i and 3802i access points

In this blog, I would like to explain how we could interpret transmit power levels on the Cisco controllers and access points. On 2.4 Ghz, the transmit power levels is not that complicated.it is pretty much dependent on the allowed transmit power and antenna gain. The max power level shows 23 dBm with power levels ranging … More Cisco access point transmit power levels

I have put together various 802.11 definitions and standards  from various sources available online and as always wikipedia had some detailed information on this context. 802.11 standards comprises of layer 1 (physical layer)  and layer 2 (media access control) specifications of  for implementing wireless local area network (WLAN) communication in the 900 MHz and 2.4, 3.6, 5, … More 802.11 definitions, acronyms and what next in wifi industry

As wireless engineers, at some point of our career, we have come across these questions on what is the maximum allowed radiated power from an access point or what is the max EIRP  allowed in a particular radio band. I am just putting these basics down so the it is easier to co-relate future discussions or contents in … More WLAN operating channels and frequencies

A WLAN regulatory domain can be defined as a bounded area that is controlled by a set of laws or policies. Currently, there are governing bodies in many countries around the world. Many countries follow standard set by FCC, ETSI, Japan, Israel etc. Please note: While all these countries follow FCC /ETSI rules, the validity period of type approval certifications varies … More Regulatory domain and compliance
