We wouldn't need as much bandwidth
We wouldn't need to break into the upper frequencies if:
*websites were designed properly and didn't push a bunch of junk phones can't understand
*Advertisements didn't constantly attack your connection trying to download new data.
*We settled on a single standard, no more of this WiMax vs HSPA, GSM vs. CDMA, etc. Preferably something royalty free.
*Frequencies were allocated by location, not carrier (IE, a tower's antennas will receive all carrier's signals and separates them in the base station itself) along with my previous point, it could open up quite a lot of spectrum
*Scrapped most of the analog radio and TV channels and instead pushed them over something like Multicast over HSPA+ and not require a license.
