Helium Indoor DAS

For indoor Helium Hotspot, the transmission distance is generally increased by adding antennas, filters and amplifiers . Antennas are selected from FRP high gain omni antennas and directional flat panel antennas. Filters are selected for cavity filters with high out-of-band rejection and low insertion loss in working band. Amplifiers require simultaneous enhancement of transmitted and received signals, i.e. bidirectional amplifiers or boosters, to compensate for insertion losses in feeders and connectors. Since the amplifier needs to be powered, a Bias Tee is required for the convenience of power supply, which requires the use of feeder power supply technology. If you want to further enhance the signal, you can use a 2-way power divider, or a 3-way power divider, or a 4-way power divider to divide the signal of a miner into two channels, 3 channels, and 4 channels, respectively, getting better performance in different direction.
