Communications Systems
Then to Now

by Greg Shea

Len Jacobson takes on Communication Systems from drums and smoke signals to telegraph, telephone, radio, cell phones, and the Internet. Len is very adept at taking the complexities of the underlying science and making them clearly understandable while fascinating at the same time. The course offered in the Fall session will cover how text and voice messages, signals, frequencies, bandwidths, interference, Wi-Fi, cellular, satellites, and the Internet actually work. Len will show how the security features for these systems function and how you can best protect your privacy. This class will leave you with a better understanding of how the evolution and development of communication systems has changed how we learn and how we live.
Anyone who has met Len understands what a skilled communicator he is. If you were fortunate enough to take his class on Brooklyn, you understand how gifted he is as a researcher and storyteller.
His class on Time and Navigation displayed  the depth of his technical expertise. With knowledge and humor Len told the story of how we got from the earliest times to present day satellite  GPS systems. Join Len again for an update on all communication systems.
