6 1/2 types of Wi-Fi

Image
There are different PHY types or Wi-Fi types which are simply put different standards of use for each frequency. There are currently 6 Wi-Fi types or standards available today. The standards for Wi-Fi are defined by the  IEEE   in 802.11. The following are amendments to the 802.11 standards.  Wi-Fi 1 (802.11b) 802.11b or Wi-Fi 1 as it has recently been deemed. Was ratified by the  IEEE  in 1999. This technology is limited to 2.4Ghz only. It had a max bandwidth of 11Mbps. Wi-Fi 1 distance from the router. With free space path loss. https://www.imgtec.com/blog/802-11b-802-11b-question/ This technology is extremely outdated and holds back Wi-Fi networks from optimal performance. While all routers and Access Points(AP) are capable of supporting Wi-Fi 1, it is strongly encouraged to remove this support from your network. I will cover details of why later. If you happen to have something that is from the early 2000s that is still working...

Ekahau GPS Survey

Image
 There are a few abilities with the Survey app out from Ekahau that I have found to be great improvements on the days I walked around with my connect-a-desk and my bulky laptop doing my wireless surveys with a SideKick. The light weight iPad is one such improvement, another is the ability to perform GPS surveys natively with the iPad. They have come in handy for those few outdoor areas the customer wants surveyed. I have used it both for APoS (AP on a stick) surveys and validation surveys. In this post I wanted to share how to set up a GPS survey, then a couple tips and tricks. Starting a GPS Survey To start a GPS survey is very simple you don't need a floorplan or a premade Ekahau file from Pro, all you need is your iPad with either a Wi-Fi connection or a dat plan and a good signal. You will not need a data plan or Wi-Fi connection to perform the survey, only needed for initial setup of the survey.  To begin you create a new project in the Survey app on your iPad then select...

Site Survey with Cisco Meraki APs

Image
 Having done a few APoS surveys with Meraki APs I wanted to share a couple little tips. This is just gonna be a short little post about RF profiles and applying settings to the AP.  While many of you may know that you can put the AP into Site Survey mode from the local status page of the AP.  To access the local status page follow these  instructions from Meraki's help guides. The default login for local status pages will be the serial number of the device you are accessing. If the AP has associated with a dashboard and a password has been set there you can find the login information under Network-wide>General.  The issue with site surveys with Meraki is the setting of the channel width. Even in site survey mode, this will default to 80MHz wide channels. This setting cannot be adjusted from the site survey menu in the local status page.  I have found, through talking with Meraki and trial and error, that the best way to apply settings to the AP is to set...

I can Wi-Fi. You can Wi-Fi.

So you are setting up your home wireless router. Whether this is because: you don't want to use the ISP provided router anymore, you are trying to recoup that $12/mo that they charge you to lease their device, or maybe you want to learn a little about Wi-Fi and how to manage it at home. This article will be a long, all-in-one knowledge base for things you might need or want to know about your home wireless network. This is not a step by step guide on how to set up a perfect home network just a reference for knowledge. The sections are laid out as listed in the table of contents. I hope this helps!  Table of Contents Wi-Fi Basics 2.4Ghz & 5Ghz BLUF 2.4Ghz 5Ghz Router Capabilities Wi-Fi 1 Wi-Fi 2 Wi-Fi 3 Wi-Fi 4 Wi-Fi 5 Wi-Fi 6 Modems Best Practices Devices Before we dive in, there is one thing that you must know about Wi-Fi. The answer to almost every question regarding Wi-Fi is, "It Depends"( Sam Clements ). This is not intended...

PiHole 4.0 Update

I know this is not about Wi-Fi but it is something I recently ran into. I am using a PiHole  as my DNS server at home. However, during the most recent upgrade to 4.0 the FTL failed to upgrade properly. After running, "pihole -up" I received,      [✗] Backing up index.lighttpd.html No default index.lighttpd.html file found… not backing up … [✗] Downloading and Installing FTL Error: Unable to get latest release location from GitHub The solution is here:  Type on your PiHole: sudo nano    /etc/resolv.conf Change the name server from 127.0.0.1 to 8.8.8.8 for googles DNS server. Save and quit the document. Then again run: pihole -up This will allow your pihole to reach Github and update the new FTL.

Pandora's Box

Hello World!  I am Stephen Frain. I am new to the world of wireless engineering. However, I have been working in IT since I graduated with a BA in History from the University of North Georgia. Yes...I get many quizzical looks when I tell people I am a history major while I am fixing their computer, network or other electronic devices that might not even have to do with IT. The short version of a rather long story is; I graduated found there were no jobs with a history degree and decided to use my computer science minor as my means of getting into the IT world. I was fortunate enough that a family friend gave me an opportunity in the Point of Sales industry. I started prepping, installing and supporting small grocery store networks, servers, and registers. I got into working with SQL, C# (Hence the intro), and HTML; all three were what the software we resold was utilizing. While there I went to do some training for the army; I am in the US Army Reserves. This training allowed me a...
