The QUAD Series is a range of external 3G/4G-LTE cellular transmission solutions increasing dramatically the signal resiliency in critical conditions for live video transmission. The QUAD Series is designed to be used in combination with AVIWEST’s PRO Series, RACK series or AIR series transmission devices, as well as HE4000 UHD encoder in order to add, extend or remotely-locate transmission capacities over cellular networks. The QUAD Series portfolio includes two solutions: QUAD Antenna and QUAD CellLink.
