PrimAer is a repeater system that can improve poor mmW 28GHz band indoor/outdoor wireless environments. This repeater is installed and operated between the base station and the terminal(phone), and can improve operator's network and facility infrastructure efficiently to provide 5G(2X2 MIMO) service.

- DU(Donor Unit), SU(Service Unit)
- DU: Internal Dual Polarization Antenna (±45º) and 2X2 MIMO support
IF signal interface with SU (1 optical cable)
5G base station 28GHz signal transmission/reception and acquires TDD sync
- SU: Internal Dual Polarization Antenna (±45º) and 2X2 MIMO support
Can expand service up to 4 SUs
- DU & SU each applied with Analog Beam Forming Technology
