E Pluribus Unum Wireless

That's what the Internet is, too -- many networks acting as a single network, because carriers move data first and talk about money later.

But if it were up to the carriers, the Internet might never have been invented.

I was a telecomm reporter 20 years ago and I remember it well. Owners of data networks wanted exclusive control of customers, or at least wanted to be paid first before taking other networks' data.

The Internet, with its government funding, offered another way. First you interoperate, under a single standard, and then we'll talk about who gets paid what for their infrastructure. It's called "peering," in that I take your traffic and you take mine, as Encyclopedia.com explains. It worked. It still works.

Peering was never demanded in the wireless space. Instead, the government sold exclusive use of frequency bands to the carriers. The result has been the creation of multiple incompatible networks, which is how the biggest carriers -- AT&T (T) and Verizon (VZ) -- like it.

Even the development of a single global standard for mobile broadband, LTE Advanced, hasn't pushed the big guys toward interoperability. It's not in AT&T's interests to be anything but a monopoly, or a shared monopoly with Verizon, as CNET notes.

When the rest of the industry, organized as the Competitive Carriers Association, which now includes Sprint (S) , tried to push AT&T toward interoperability, the bigger carrier simply refused, saying the group had other options, as Fierce Broadband Wireless reported.

Thus the wired Internet is, from the user's point of view, one network, while the wireless Internet is multiple networks. This means duplicated services in high-traffic areas, and no service at all in low-traffic areas.
