Bandwidth Cell Phone Carrier

Lecture 23: Modulation, Part 1 - MIT OpenCourseWare
If the carrier frequency is much greater than the highest frequency in the message, AM with carrier can be demodulated with a peak detector. z(t) z(t) y(t) R C y(t) t. In AM radio, the highest frequency in the message is 5 kHz and the carrier frequency is between 500 kHz and 1500 kHz. This circuit is simple and inexpensive. ... Visit Document

Understanding Mobile Wireless Backhaul - Fujitsu Global
Today, most cell towers are serviced by one to four T1s, equivalent to 1.5 Mb/s to 6 Mb/s. The addition of 2.5G and 3G data services will increase the need for more bandwidth to cell sites, but the requirements are still relatively modest. The amount of bandwidth on a wireless network is ultimately constrained by two factors: the ... View This Document
