What Frequency band IS-136 designed to operate? kwwilliams 18-April-2008 10:59:35 AMComments 1900 MHz Posted by crouse 1900 MHz Posted by waqqas1 Operates in 1900 MHz frequency band. Posted by akumar_8181 Digital AMPS. Designed to use existing channels more efficiently, D-AMPS (IS-136) employs the same 30 kHz channel spacing and frequency bands (824-849 and 869-894 MHz) as AMPS. By using TDMA instead of frequency division multiple access or FDMA, IS-136 increases the number of users from 1 to 3 per channel. An AMPS/D-AMPS infrastructure can support either Analog AMPS phone or digital AMPS phones. (The Federal Communications Commission mandated that digital cellular in the U.S. must act in a dual-mode capacity with analog). Operates in the 800 MHz band and 1900 Mhz. Posted by sagitraz |
