Is 4G Really 4G? Just the Facts, Ma'am!

I keep seeing wireless companies advertising they have 4G speed or the largest 4G network, but I started to wonder about the claims and what they really meant. The tiny print in the TV ads provided some guidance that there are limits to the claims. However, it was not until I read this interesting article from Engadget that provided clarity to the ad claims. Bottom line? 4G might really be 3.5G or other fraction above 3 but below 4. An interesting read . . .
