I’net security

The I’net is like a neighborhood with a bunch of teenagers constantly checking the doors and windows to see if they can get into houses and do something to brag about their successes. Seldom is it worse than just trespassing and graffiti but every now and then the behavior can have more important consequences such […]

Winds of change: billing paradigms in media delivery

The ‘net neutrality’ thing was about billing and bundling. I’net access is something usually bundled. The cable companies bundle it as an add-on to their traditional media delivery. Telephone companies added it to their land line voice services. Cell phone companies bundle it in with their voice, and now, text services. When it comes to […]

The options mention ad hoc WiFi, dial-up, and amateur radio. You could also take inspiration from groups that are working to create an ad-hoc […]

It is a cell phone without the screen or keyboard but with a wifi router built in. The Virgin Mobile Broadband2go plan is a prepaid, $40/mo for unlimited but ‘reasonable’ use depending upon the Sprint […]

Femtocells, VOIP, and cordless phones synthesis?

It has been a big change taking a lot of time. The landline telephone network started development just a bit over 100 years ago. Cable TV is less than half that and its expansion into networking is less than half of that. Cell phones have an age similar to cable networking of only a couple […]
