Repeater. Power output listed is conducted.

This Class B Booster is deployed with 5 Watt maximum ERP according to §90.219(d)(3). 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. 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. The antenna used for this transmitter is to be fixed-mounted on indoor / outdoor permanent structures. 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.
