In today’s world we want our cellular phones to work everywhere! Inside buildings, our homes, in the basements, even in elevators! Electronic Engineering uses its expertise to amplify the cell signals and redirect the signals into hard to reach places inside buildings, even homes. Known in the industry as bi-directional amplifiers these products collect signals from the nearby cellular towers, and then through cabling, fiber, and internal antennas redirect the signals to interior locations with poor reception. These can be geared to a singular cellular carrier, or the full spectrum of cellular carriers. Even 4G LTE application systems that use high speed data for internet. Without proper engineering and site analysis, amplifiers can cause interference with the cellular networks, so appropriate planning is a must.
EE has also been installing BDA installations that cover the public safety radio frequencies so emergency responders can successfully communicate inside businesses and schools. Many communities are even suggesting ordinances for all new construction or substantial renovation or additions that first responders must have adequate communication before an occupancy permit will be issued.
Engineering, spectrum analysis, and specific placement of the antenna transmission system – are keys to a well performing amplification system. |
