Telepocalypse: FLASH-OFDM is disruptive mobile internet technology

Hmmm. Definitely one to watch!

From Telepocalypse: One to watch:

According to The Feature, Siemens are working with Flarion to deploy FLASH-OFDM technology in the 450Mhz range. I've written previously about Flarion and why it’s a significant technology.

This announcement is interesting because it very much follows a "disruptive innovation" trendline. The frequency band in question isn't universally available around the world, so isn't attractive to high-end business customers who travel internationally. But the lower frequency means much better in-building signal penetration, as well as lower cell site density (as the article notes). The spectrum is also pretty cheap. This means more attractive economics than traditional 3G services in achieving acceptable coverage. The average user couldn't care less about megabit throughputs on a mobile handset, so the lower frequency and peak throughput isn't a big deal. Plus Flarion's FLASH-OFDM is highly spectrally efficient when measured by total system throughput (rather than peak throughput for any one handset).
