Grant Notes

In-Building DAS Industrial Booster. Power output listed is conducted. This device supports LTE and 5G NR modes and simultaneous transmission as documented in this filing. This filing has compliance demonstration information and test data only for SISO (single-input single-output) booster system configurations; additional equipment authorization is required to allow this device to be used in MIMO (multiple-input multiple-output) industrial booster systems. Users and installers must be provided with appropriate antenna installation instructions and transmitter operating conditions, including antenna co-location requirements for satisfying RF exposure compliance. The antenna used for this transmitter is to be fixed-mounted on indoor structures. The single unit RF Exposure compliance for the device was based on maximum antenna gain 3.0 dBi (in the 600MHz band and 3.5dBi in the 700 and 800 MHz bands with minimum separation distance of 20 cm. RF exposure compliance must need to be addressed at the time of licensing as required by the responsible FCC Bureau(s), including antenna co-location requirements of §1.1307(b) (3) of the rules.
