Wireless Networking

I was surprised to find out that the first wireless network is cell phones. I never heard it referred to as a wireless network, but thinking about it, it makes sense. I am not familiar with the 1G, 2G, 2.5G, 3G, or 3.5G. I did not get my first cell phone until 2019 and 4G was ending. I ask both my parents, and they both remember the development of cell phones. They remember having 2G networks where talk and text. They both said how cool it was when they got the first 3G smart phone, the blackberry. Then in 2011, my mom got her first 4G iPhone, and she kept telling dad to, but he resisted until 2012. They both the simultaneous support was amazing. Now our house is completely 5G with LTE capabilities. We have been using the hotspot for years before my sister and I got our smart phones. My mom would connect us to our hotspot to use our iPads on long trips. In our home, we had Wi-Fi for as long as I remember. The access point has always been central in our home to get the best range. We have upgraded many times as we have gotten more wireless devices to increase the transfer rate. Now when we travel, we use our cellular network, but our hotel must have free Wi-Fi. Looking further into it, Wilkes-Barre center city has a Muni Wi-Fi network, but I never really looked. One of the coolest things that I think is offered is Bluetooth I have earbuds, a smartwatch, and my car has Bluetooth. I was never familiar with a piconet, but I use it all the time between my devices. As I read on that hotel Wi-Fi is really a wireless wide area network. Next, internet of things, we use them all the time too. Traffic congestion, our home security unit, and the Ring doorbell to name a few. I wonder if the IOT devices ever surpassed 50 billion as Cisco predicted.

I was always curious if something like Wired Equivalent Privacy existed and my curiosity was answered. In our home our printer (It stinks) always disconnects from the network, and when reconnecting it gives us a Wi-Fi protected access code before using it. Then I decided to look at our access point to see if we had any of the protocols mentioned. It did show a media access control address, and a service set identifier. Unfortunately, I had to tell my dad about wardriving because he never changed the default name or password. However, I think I might be okay from an over-the-shoulder-attack, evil twin attack, or man-in-the-middle attack because I usually do not connect to the wireless network of businesses. I am more concerned about bluejacking, bluesnarfing, and bluebugging because I always have my smartwatch on. I do have my autoconnect on, so I will have to be more careful.
