Help with Question: What is 4G

I have a presentation that I am giving where I have to discuss what the difference between 3G and 4G is. I need to simplify this idea down to the basics and I need to first know what 3G and 4G are in the first place. I have a very vague knowledge about this area and would love some help from people who know what they are talking about. Any Help would be appreciated.

Howcum I'm the first one to open his mouth around here? Maybe I should get a life?

Go to www.speedtest.net, and measure your connection speed. The unit of measure is Mbps MegaBits per Second. What does it mean in the real world? One mgbps is barely adiquate to watch a YouTube or Hulu without interminable BUFFERING breaks.

My current 3G just measured .83 download, .58 upload. (that'sPOINT 83! Not even a whole ONE) Thank You Verizon for this very SUBSTANDARD rate.

The 4G is in the realm of 18 whole mbps. or more. It's like magic. I download enormous files in seconds - minutes at the most, that would take hours (if not days - even if we could stay connected, at 3G. )

If you're not in an established 4G area, don't waste your money. Wait for 4G to come to you.

I actually download over 5GB/month on my phone right now (podcasts, apps, etc), and that's just on the 3G netowrk! These smartphones are micro-computers that we can shove in our pockets, and I use my Droid X as such :smileyhappy:

Essentially, 4G will bring faster data speeds (like Neander said, I get up to 1.5Mb/s on 3G, and get anywhere between 12Mb/s to 33Mb/s over my 4G modem. Also, a standard is going to be put in place, eventually, that will allow voice to travel over 4G (VoLTE), potentially allowing for a unified high-speed data and voice service. This would be fantastic, considering that the majority of the world is moving to LTE, so global phones/modems could be significantly easier to make. In fact, even Sprint is considering rolling out LTE and dumping their current WiMAX 4G standard.
