This is PERFECT for "Off Topic" wireless because...

Haha, this should be a good one, for the younger crowd, there was actually a phone booth on every corner at one time. Pay phones were everywhere.

No cell phones, no beepers, until later when the pay phone became very valuable answering the beeper.

Nope, the only way you stayed in touch was to drop a dime. The first answering machines at home were a big development.

In the seventies it got easy to use a pay phone because I had a AT&T calling card, you just put a code in and talk as long as you want on the pay phone. No coins needed. At work it was sort of like a call box the police would use, you would call in on a routine basis to see what's going on.

In the news media business we did have two-way radios, but didn't say much on them because the competition was listening. Usually the common message on the radio was.. call the office and you would immediately look for the nearest Payphone.

The need for phone booths or pay phones at all, is long gone, I feel bad for the telephone employees that were the ones that would be constantly going around and emptying the coins from the pay phones that again, were on every corner. Payphone change collectors were a very large workforce for the phone company.

The Australians have it all figured out:

There was a radio site I used to visit. No cell carriers on site, remote location, took about 3 hours to get to from pavement.
Cell phone service was very spotty and getting a clear phone call was usually impossible.

Until I found a 90º inside corner on the security fence acted like a nice little corner reflector. If I stood in the right place, the cell phone would work great, calls were clear. Step out of the sweet spot, and the call would drop. I had a little pile of rocks at the right focal point. It looked across the mountain range and out into a valley where there was a cell site I could hit.

Initially looking at the image, I thought they were talking about whisper dishes.

I love how simple things and shapes have so many uses.... !!
