Abstract :
In presenting this report it is the aim of the Committee on Communication not so much to present a complete report of all the developments which have been made during the last Institute year in the art of electrical communication, but rather to single out those advances which it is thought will be of greatest interest to the members of the Institute. Topics covered include: printing telegraphy; "ticker" transmission; submarine telegraphy; machine switching telephony; telephone toll cables; radio telegraphy; transatlantic radio telephony; radio propagation tests; radio broadcasting; electrical transmission of pictures; inductive coordination; telephone service for the deaf; characteristics of speech; loading of telephone circuits; fire-alarm, and police-signal, and train-control systems.
