Telephony, August 14, 1920, page 17:
Michigan College Plans Wireless Telephones for Farms.
Wireless telephony as a practical adjunct of farm life is to be brought before Michigan farmers this fall by the electrical engineering department of Michigan Agricultural College, Prof. Arthur Sawyer, of the department has announced.
With a view to influencing farmers throughout the state to install receiving apparatus, a demonstration of wireless telephony will be given at the state fair.
The college contemplates establishing a regular wireless telephone service, through which weather reports, crop reports, extracts from lectures on agricultural topics, etc., will be disseminated.
Research work at the college this year has been aimed at determination of the minimum practical installation of apparatus which would enable a farm home to pick up the wireless communications from the college. It is not expected that the farmers should be able to communicate themselves but merely that they should be able to pick up the college messages.
