Bandwidth Caps Inevitable

T-Mobile USA's swift retraction of a 1 Gbyte monthly cap on 3G data access to G1 Android phones was wise. The cap was paltry, compared to competing offers available from Verizon, AT&T and Sprint. Granted, T-Mobile probably wanted to avoid taxing its brand-new 3G network, and likely was aware that five class action lawsuits filed against AT&T for misrepresentation suggest legal liability if 3G performance was compromised by excessive demand. 

That said, bandwidth caps are inevitable for mobile users, and likely inevitable for fixed broadband access as well, as video becomes a more-common application. The reason is simple: video consumes an order of magnitude, or in some cases two orders of magnitude, more bandwidth than anything Internet service providers yet have encountered.

Anybody who has followed the cost of fiber-to-home construction knows how expensive access to core bandwidth actually is. In fact, the business case is quite difficult, under nearly all circumstances. 

User expectations aside, when demand jumps that much, one can expect either bandwidth caps, or metered usage or new higher-priced tiers of service that better match the underlying cost of providing service. For some of us, Internet access, using broadband, is as much a utility as water, electricity, wastewater services, heating or cooling. 

And it simply does not make, long term, to provide most of those services on a "flat fee, irrespective of usage." There are real costs (carbon footprint, drilling, refining, construction, maintenance) for providing clean water, water removal or electrrical services. It would not make sense to provide them on a flat rate basis for all customers, as well as that might work for most customers, most of the time.
