Why Is Tapper an Indispensable Passive Component for Indoor Coverage?
Jan , 17 2026
In the field of mobile communication engineering, the success of an Indoor Distribution System (DAS) depends not on the raw power of the signal source, but on the "art of distribution." As 5G transitions toward Sub-6GHz and higher frequency bands, space path loss and feeder attenuation increase drastically. To achieve seamless "carpet-style" coverage in complex skyscrapers or underground facilitie...
