| Actual Throughput?
I wonder what the latency and actual throughput numbers will look like with an overloaded cell tower and protocol overhead?
Regardless, this could be interesting as I'd like to take a reasonably middle-ground latency, high bandwidth connection with me on the go.

| The challenge will be providing enough backhaul to every site to supply that much to each user. Is a major challenge already with EVDO/HSDPA to just get 2-3Mbps.
BTW, WiMAX 802.16m is spec'd to go to 1Gbps but we'll probably never see it. Sprint actually has enough spectrum to do 1Gbps. Might be used for backhaul.

WiMAX is way ahead of LTE. |

| True... while WiMAX is way ahead of LTE and UMB, WiMAX is still a relatively new product out there, and isn't compatible with anything else.
I suspect the GSMA will ensure that LTE is backward compatible with UMTS/HSDPA/GSM networks which already have +2.5 billion subs.
Similarly, CDMA has +375 million subs in multiple countries. UMB would most likely fail back to CDMA 1x/EVDO networks.
WiMAX would fail back to ?? WiFi?
WiMAX needs to deploy lots of gear globally with lots of retail equipment.

| I'm not certain but I don't think LTE itself will technically be backward compatible to HSPA, but it is likely that an LTE device will include an HSPA radio as well.
WiMAX radios will likely include a WiFi radio in most cases. And is some cases, some of Sprint's WiMAX devices will have EVDO, like combo laptop cards.
But as we've discussed, LTE devices will likely be limited to cellphones and laptop cards and devices controlled by LTE carriers. WiMAX devices are specifically targeting consumer electronics devices, uncontrolled by carriers, so has a chance of much broader penetration. In terms of getting the consumer electronics industry on board, WiMAX is way ahead and will have product out next year. |
