Modern Mechanix Round-UP

Today on Modern Mechanix we look at this 1973 Popular Science article about the debut of the world's first cell phone, Motorola's Dynatac.

In super-dense Manhattan, for example, a transmitter and its antenna may be designed to cover a 15-block area. Another transmitter in a residential Brooklyn area may cover several miles. As the number of subscribers grows, more transmitters would be added.

I don't think they realized quite how many more antennas they'd need. Here is a map of all of the cell station antennas within 1 mile of the 10001 zip code in NYC. There are 1494.

Also today, a beard clinic that helps men develop their own custom shaving strategy, Polish dogs trained to lay telephone lines, deep sea divers used to solicit cash, an interesting approach to preventing bank robberies by using mirrors and a pretty nice looking home on a train.

Fixed, thanks. I usually edit my posts in Wordpress, then move them over here. Last night I upgraded to 2.5 and apparently the visual editor and I don't get along.

I love polish dogs . . . with sauerkraut and spicy mustard!
