Fairly positive Clearwire article.

Didn't really want to paste it because of length, but an interesting read nonetheless.

Wish the editor knew the difference between Mhz and Ghz...

LOL. That was an embarrassing typo.

It is very important to have proper downtilt on their towers or people in the next state will be connected to that tower.

 

I wonder what kind of ping that would have.

As long as the SNR is fine, pings would be okay too. Light travels pretty fast you know...

 

186,000 miles per second. It isn't just a recommendation. It's the law.

HAHAHA its Joan Lappin. Wasn't she the heckler during the Oct 7th Network Vision conference that called out the Sprint executives for not just contracting out its LTE deployment to Clearwire for 600 million? If it is her, then its kinda embarrassing to see 2.5 MHz as a typo.

I have come across an external antenna that should allow people to receive Clearwire 2.5Mhz signals on their phones. It is a little cumbersome, but the building penetration is excellent.

Joan also doesn't know how to write...or at least copy-edit...an article. 20,00 sites? You gotta be kidding me.

 

Side note: I think that Cablevision has a 30,000 hotspot WiFi network covering much of their service area (NYC/NJ). The end goal is different (provide smartphone users a reason to get cable home Internet, because WiFi everywhere doesn't count against caps and is faster than LTE at times, at 15 Mbps down, 4 Mbps up). However you could apply the same idea to TD-LTE: build a huge microcell network to inundate an area with capacity (actually, TD-LTE would work better because it's built for a cellular environment and there's actually more spectrum available there than on 2.4GHz ISM/WiFi).

 

My bet is that the China deployment is all in one city, or a portion thereof, with micro/picocells. Lots of capacity (which is good, since last I checked wireline infrastructure is hit-or-miss over there), not a ton of coverage overall, but decent coverage in the area due to site density.

 

You'll never see that sort of thing in the U.S. though, since backhaul providers aren't just going to give away the hundreds of backhaul PoPs necessary to make something like that work. Cablevision's OptimumWiFi works because CV already had high-bandwidth infrastructure reaching their entire footprint; they could just strap a DOCSIS-backhauled WiFi access point to the coax and, without any additional backhaul fees, build a WiFi network across their footprint.

I prefer 24dbi 2.4GHz grids. They even work well on PCS spectrum (not much loss of gain due to imappropriate antenna design). Though that'll kill any MIMO that Clearwire has going on.
