N78 mid-band radio
3.3–3.8 GHz TDD radio with a 100 MHz carrier — the core mid-band spectrum for 5G Standalone deployments and private networks.

Studio gNB is the radio access half of the MMT 5G/6G Studio — a tripod-portable 5G Standalone base station. An N78 mid-band radio (3.3–3.8 GHz) with a 100 MHz TDD carrier, 4×4 MIMO and 2× 24 dBm PA output, it broadcasts a live 5G SA cell that COTS UEs and Studio Field handsets camp on, register through, and pass traffic across.
It plugs straight into Studio Core over the N2/N3 interfaces for a complete gNB-to-core stack, and every call flow is verified against the 202 test cases in Studio TestBench. No base-station room, no fronthaul cabling, no vendor lock-in — power it, point it, and it’s on air.

What it does.
A complete radio unit and gNB in one enclosure — the on-air end of a full 5G Standalone network you can carry into any lab, classroom, or demo floor.
4×4 MIMO
Four spatial streams for higher spectral efficiency and throughput, with 2× 24 dBm power-amplifier output driving the antenna array.
Pairs with Studio Core
Connects straight to Studio Core over N2/N3 — the Python control plane and C/DPDK UPF — for a complete gNB-to-core 5G SA stack.
Full SA call flow
SSB / SIB broadcast, RACH, RRC setup, and PDU-session bearers so COTS UEs and Studio Field handsets camp, register, and pass traffic end-to-end.
Rel-17 compliant
3GPP Release 17 signalling across NGAP, RRC and the NR physical layer, verified against the 202 test cases in Studio TestBench.
Tripod-portable
The whole radio mounts on a field tripod and runs off a single DC supply — carry a live 5G cell into a lab, classroom, or demo floor in minutes.
Lab + field ready
Bring-up a private 5G network for throughput, mobility, VoNR, and slicing trials without a base-station room or vendor lock-in.
One-box RU + gNB
Radio unit, antennas, and baseband in a single enclosure — no fronthaul cabling to integrate. Power it, point it, and it's on air.
Vendor-agnostic interop
Standards-based N2/N3 interfaces mean it interoperates with third-party cores and UEs for conformance and interop labs.
RF & system specification.
Mid-band 5G Standalone radio, tuned for private networks, interop labs, and hands-on 5G training.
