Throughout the site, you would see mention of RJ45. I am sure some people may not know what RJ45 is, and if they do, why is the only port for telecommunications. First, RJ45 is the square like jack on the back of routers, and modems. For example, a typical home router will have 4 RJ45 ports for LAN (Local Area Network), and one RJ45 for WAN (Wide Area Network). The RJ45 can replace the need for telephone, and coaxial with a simple modification to convert everything to RJ45. This will eventually reduce the prices of various items, and since there is a single standard for ports, this makes it easier to maintain, and conduct repairs.
For Internet, the RJ45 is a natural choice for internet services. This is because most routers will have 5 RJ45 jacks. You won’t find 5 RJ11 jacks, or 5 coaxial jacks for routers. Instead, you would find 4+ RJ45 jacks. The WAN might be different only because of the constraints the former company placed on themselves. Once fiber optic services are rolled to the premise, RJ45 will just be the natural standard.
For telephone, there is something called SIP technology. SIP is an open standard to VOIP solutions. If you used Skype, or Google Talk – then you used VOIP. If you made a FaceTime call, you used VOIP. If you have an Ooma, or Magic Jack, then you are using VOIP. Telephony over the Internet makes sense when compared to managing the old telephone network that would only become harder and more expensive to maintain. With that being said, SIP will be used. When using SIP, you would acquire an ATA (Analog Telephone Adapter) which will allow you to plug your phone into the ATA, and the ATA plugs into a RJ45 port. If you have a SIP phone, then you would plug the phone into an RJ45 port. If you have a Wifi phone, then your phone connects to the wireless LAN which connects to the Internet – usually to a modem, and using RJ45. All of these uses RJ45, and SIP has been around for decades, so the technology is proven to work, and in many cases more so than the POTS (Plain Ordinary Telephone System).
Television will be the hardest to justify, but it can be done. If you used your computer to watch Youtube, you are using the basic premise of IPTV (Internet Protocol TeleVision). Your computer or phone connects to the router which then uses the Internet. With that said, many TVs sold these days are smart TVs, and those TVs can have a TV app to stream network, and authorized cable TV signals to the app that is on the TV. This means things will simply just work. For those without smart TVs, there is an adapter (such as Roku). And since all is connected to the Internet, we already established the Internet using RJ45. Ideally, televisions will just have an RJ45 jack to connect directly to the LAN, and from there – the Internet.
