Re: Hard to find a laptop w/out WiFi, WiMAX to follow same path
If there's only 1 site.... they had better have 500MHz worth of bandwidth to share, or its going to get filled pretty fast.
A town/city of up to 5,000 can probably do well on a site.
Cities like Los Angeles and NYC had better have sites every mile at least.

As I said, WiMax covers an entire metropolitan area and there are no handoffs - a single connection. More like an FM radio station in that respect than a cellular or WiFi network. Of course, there are specific locations with coverage issues such as a subway (with any broadband wireless network).
There are problems with AT&T 2G/3G handoffs in New York where I live. |

That's partially my point.
If I'm using a WiMAX handset/PDA/laptop and go into a subway, will it handoff ? If it does handoff... to what ? WiFi, UMTS, EVDO ?
WiFi has a basic infrastructure
GSM/UMTS/WCDMA has a MAP core infratructure (using SIM / IMEI)
CDMA/EVDO has an ANSI infrastructure (using ESN)
WiMAX has ... ?
I have AT&T 3G, and I have no issues handing off to 3G or GSM. At least 25% of my calls go from 3G to GSM (suspecting capacity issues - only 10MHz is deployed on 3G here).
This would be similar to having a Verizon Wireless handset handoff to AT&T or Nextel. While it can be done, is it ?
