Voice and data choices and availability in remote areas and what to expect Voice calls and data transmissions use the same frequencies, channels and modulation, however, data is only available when the phone is within a digital signal area, therefore, you may find yourself in an area where voice calls are possible on Analog but data is not functional. An 800 Mhz booster will expand coverage area for both Analog and Digital and as long as the digital signal meets the minimum signal strength and signal quality a cellular switch will command the phone to stay on digital. In essence when using a booster the digital coverage is expanded and preferred, therefore it is possible to make data transmissions when using a booster in areas where they were not possible without the booster. Wireless data cards have lower transmit power than handsets, therefore it is even more important to have a booster in remote areas when using a data card with a laptop for data over cellular networks.
