Wireless networks have been incredibly successful, from home Wi-Fi networks to the billions of mobile devices in use across the planet. So successful, in fact, that some have come to believe we no longer need wires.

We developed this fact sheet to clarify some misconceptions about what wireless Internet networks are capable of and the importance of fiber optic cables in building better wireless networks as our bandwidth needs continue to increase.

This fact sheet defines important terms, offers some key points clarifying common misconceptions, compares 4G and 3G wireless to wired cable, and more. We also include references to additional resources for those who want to dig deeper.

If you are a current or potential Verizon customer, by now you know that you no longer have the option to order stand alone DSL. When the business decision became public knowledge in April, DSL Reports.com looked into the apparent step backward and found existing customers were grandfathered in but:

However, if you disconnect and reconnect, or move to a new address -- you'll have to add voice service. Users are also being told that if they make any changes to their existing DSL service (increase/decrease speed) they'll also be forced to add local phone service. One customer was actually told that he needed to call every six months just to ensure they didn't change his plan and auto-enroll him in voice service.

By alienating customers from DSL, Verizon can begin shifting more customers to its LTE service, which is more expensive. Susie Madrak, from Crooks and Liars, speculated on possible repercussions for rural America:

Rural areas could see the biggest impact from the shift, as Verizon pulls DSL and instead sells those users LTE services with at a high price point ($15 per gigabyte overages). Verizon then hopes to sell those users cap-gobbling video services via their upcoming Redbox streaming video joint venture. Expect there to be plenty of gaps where rural users suddenly lose landline and DSL connectivity but can't get LTE. With Verizon and AT&T having killed off regulatory oversight in most states -- you can expect nothing to be done about it, despite both companies having been given billions in subsidies over the years to get those users online.

The belief is that current DSL customers who don't want (or can't afford) the switch to the LTE service will move to Verizon's cable competition. Normally, losing customers to the competition is to be avoided, but when your new marketing partners ARE the competition, it's no big deal.

The other is rural access lines; we have been apprehensive on moving, doing anything on rural access lines because the issue here is, do you have a broadband product for rural America? We’ve all been trying to find a broadband solution that was economically viable to get out to rural America, and we’re not finding one to be quite candid. The best opportunity we have is LTE.

[W]e’re looking at rural America and asking, what’s the broadband solution? We don’t have one right now.

Customers began complaining in mid-2010 that Clearwire had begun to throttle their home Internet connections, sometimes as slow as 256Kbps. It wasn't clear (ba-dum ching) at the time as to what standard Clearwire was using in order to trigger the throttling—some users were told about monthly usage caps while others were simply told that there were certain times of day in which the network would be congested. Customers were frustrated at this lack of transparency, and complaints began piling up all over the Web.
