Sprint to Demo Its 2.5GHz Network Technology

Sprint is prepared to demonstrate new wireless networking technology at an event in Silicon Valley today. The demonstration will show how Sprint plans to use its 2.5GHz spectrum holdings to deliver even faster mobile broadband, reports The Wall Street Journal. Citing sources familiar with Sprint's plans, both the networking technology and handsets that can use it will be available to consumers soon. At issue, notes the Journal, is whether or not the 2.5GHz spectrum will suffice for Sprint's network plans. Signals sent across higher spectrum bands don't propagate as well as they do across lower spectrum bands. Sprint explained that it will have to build 12 to 15 cell towers with 2.5GHz to match the coverage provided by just one cell site with 700MHz. The Journal did not note what this new networking technology is, but Sprint is in the middle of deploying its LTE network around the country. To-date, it has been using its 1900MHz spectrum holdings for LTE. However, Sprint has long planned to use 2.5GHz for LTE, as well. The FCC has already approved devices that include LTE support in the 2.5GHz band, and Sprint sells one mobile hotspot with that spectrum on board. SoftBank, which acquired a 79% equity stake in Sprint earlier this year, also uses 2.5GHz spectrum for its own network in Japan.

A 15:1 ratio?!?

The article states it takes 12 to 15 2.5 Ghz towers to equal the coverage of one 700 mhz tower. That doesn't sound fiscally plausible.
Perhaps with macro cells it's not finacially possible. However, using small cells in dense urban and possibly even suburban areas may make it more palatable.

Plus more then 1 band

Duh we all know that 2500 doesn't penetrate well.. Which was part of Clears issues (among a whole slew of others)

We also know that the 1900 has some of the same problems...

OH OH OH I know....NEXTELS 800 freq!!!! Which has the good building penetration.

Which is why we have been waiting on a tri band phone....

so put them all together, and people inside AND outside, and hope that it all works and hands off the way it should....And we should all be happy campers....

More than one device

Eric, Sprint actually sells two hotspot devices with the 2.5GHz spectrum on board-the Novatel MiFi 500 and the Netgear Zing. They also sell a USB device with that spectrum on board, the Netgear 341U.
