Times I Wished I had 5G WiFi: Part I

This might seem implausible, but I think I’m a Luddite technologist – I have six computers, three personal audio players, two tablets, a supposedly wireless printer and an HDTV with more inputs than I could ever use…And yet I am an incredibly slow adopter of technology. Here’s a great example – a few years ago, I bought my mom a Slingplayer so that she could watch her TV when she was traveling. I didn’t have cable TV myself, but I put together a system she could use when she was visiting:

In case that’s not clear, my PC connects to the Slingplayer and streams video to my TV using a VGA-to-composite converter (which is sadly SD on my HDTV.) For all of the inputs on my HDTV, I didn’t have any that had the same sync rates as the PC I was using to generate video, and the PC was so old that I couldn’t successfully add an HDMI card to it. Of course, the system now needed a remote control, a role that was ably-filled by a wireless keyboard and mouse. As you may well imagine, everyone other than me found this system incredibly confusing and I basically had to come into the living room anytime anyone wanted to change the channel.  I finally gave in and got cable last year, and I now have a fairly standard setup with a set-top box connected to my TV, but no capability to stream video from my PC to the TV.

Here’s where I wish I had 5G WiFi. With 802.11ac expected to ship in the next generation of HDTVs, wireless routers and smartphones, my TV will have an interface that will allow me to access content from the outside world, whether my router is connected to the internet via a cable modem, fiber optic cable or even 4G LTE. (This nicely eliminates the PC from my setup.) And with seamless integration of 5G WiFi into all of these devices, my smartphone will also serve as a remote control – an obvious application, but not one that’s done poorly at the moment – or as a game controller. (Now my wireless keyboard and mouse are eliminated.)

Those are the simple and obvious applications – 5G WiFi eliminates the most-complicated parts of my Rube Goldberg A/V setup. But it also enables Wi-Fi Display from my smartphone – I can stream a movie or a video game from my phone directly to my TV. 5G WiFi has three times the throughput of my 802.11n wireless router, so I can stream high-quality video and do something else simultaneously with my phone – use the internet, stream audio, you name it.

As I mentioned in my last piece, I like to try to come up with technology that my mom would find useful. Not only would my mom find the 5G WiFi TV, smartphone remote and 5G WiFi Display really cool, she’d be really excited that it got rid of all of the clutter (keyboard, mouse, extra computer) that I had in my living room.
