Origin of the Cellular Concept

The discussion of ever-smaller femtocells reminds me that the cellular concept—breaking up an area into cells, and decreasing the size of cells to increase capacity—was invented in AT&T Bell Telephone Laboratories by D. H. Ring in 1947 (the same year that AT&T Bell Labs engineers invented the transistor: John Bardeen, Walter Brattain, and William Shockley). They found that you can reuse your allocated spectrum (frequencies) in different cells, and even split the cells to increase capacity of the entire system. Bravo!

Can you tell that I am proud to have served with such luminaries at AT&T Bell Labs? Please forgive me for the brief excursion in the WayBack machine.
