Can millimeter waves solve the small cell backhaul problem?

The mobile industry is counting on future wireless networks being heterogeneous: complex multi-layered systems of overlapping big and small cells, pumping out cheap bandwidth. But to arrive at hetnet we first need to figure out how to link all of those small cells together.

How the iPhone Is Driving a Wireless Bandwidth Boom

The popularity of new 3G devices such as the iPhone and BlackBerry 3G has increased the use of data, putting the backend networks under strain. And from that perspective, today’s 3G networks are like glittering skyscrapers built on a foundation of matchsticks.

Downturn or Not, Mobile Broadband Is Growing Fast

[qi:___3g] Earlier this week, comScore reported that daily web usage on mobile devices had doubled in the last 12 months, with nearly 22.4 million U.S. mobile users using their devices to go on the web.

Today, another research firm, Infonetics Research reported that despite the global economic downturn, the demand for mobile broadband is only going increase. They expect that there will be more than 1 billion mobile broadband users by 2013 vs. 210.5 million at the end of 2008. These are connections that use 3G technologies such as W-CDMA, HSPA, CDMA 2000 and EVDO. The sales of mobile broadband PC cards (and embedded 3G modules) were around $4.1 billion in 2008 and show no signs of slowing down. Read More about Downturn or Not, Mobile Broadband Is Growing Fast

Is 3G Ready for the iPhone Stress Test?

In a few hours from now, there is a good chance that as part of The Steve Jobs Show, Apple will introduce a brand-spanking new, 3G iPhone. It has some folks I know in the wireless world not really looking forward to the big surge of traffic such an 3G-capable iPhone will bring to their networks. Think of it as an iPhone-inspired stress test for their high-speed wireless networks. Read More about Is 3G Ready for the iPhone Stress Test?

4G Wireless & the Ensuing Bandwidth Boom

I sat down this week with John Roese, chief technology officer of Nortel and one of the most astute people I know in the broadband business. Since he seems to have a much better handle on the 4G timeline than others in the wireless industry, I asked him about the wireless backhaul business and the bandwidth demand that LTE will create.
