- How is power consumption?
- What about our lame data caps? Will you hit your cap in the first hour of the month?
- What about backhaul from those gigabit towers?
- Don't high frequency signals attenuate rapidly as one moves away from the antenna? How many base stations will have to be added?
- Aren't high frequency signals more readily absorbed by obstructions?
- If implemented, how well would this technology compete with WiFi, especially if Google or others were to deploy it widely?
Can you think of other "how-abouts?"
