AMU (Antenna Management Unit)

Intelligent Site Monitoring
Designed by ORAN Infra Inc. in Canada

The integrated Antenna Management Unit provides real-time telemetry of the antenna's physical state. This data is critical for network optimization and alignment verification without site climbs.

  • • GEO Location: High-precision GPS/GNSS coordinates.
  • • Physical Height: Accurate AGL (Above Ground Level) sensing.
  • • Orientation: Real-time Azimuth and Down-tilt monitoring.

RF Performance

Low PIM Design

MIMO 8 features a low PIM (Passive Intermodulation) design with super flexible jumper cables available. The innovated larger radiator and cable elimination technology ensures maximum signal integrity and minimal interference.

Friis Transmission Equation
$$P_r = P_t + G_t + G_r + 20\log_{10}\left(\frac{\lambda}{4\pi d}\right)$$

VSWR Optimization

Voltage Standing Wave Ratio

High efficiency is maintained through a VSWR < 1.5 across the entire operational bandwidth. This minimizes reflected power and protects sensitive radio equipment.

VSWR & Reflection Coefficient
$$\text{VSWR} = \frac{1 + |\Gamma|}{1 - |\Gamma|}, \quad \Gamma = \frac{Z_L - Z_0}{Z_L + Z_0}$$

Antenna Roadmap

V3.0

Baseline
Engineering Changes
  • Multi-band FDD + TDD platform
  • Coax-harness phase-shifter networks
  • Remote electrical tilt (AISG)
RF Performance & Coverage

Reference version. All deltas in this roadmap are measured against this lineage.

V3.5

Shipping Now
Engineering Changes
  • Refined array feed networks for tighter amplitude/phase balance
  • Integrated antenna measurement unit (AMU) option
  • Multi-band 600–960 MHz, 1.7–2.7 GHz and 2.5–4.0 GHz TDD
  • 8T8R mid-band and TDD arrays
RF Performance & Coverage
  • Low-band gain +0.2 to +0.3 dBi
  • Mid/high-band gain +0.1 dBi
  • First-sidelobe suppression +0.8 dB (up to +1.0 dB at 2.5–2.7 GHz)

What it means: Rural cell area +3–5%; urban cell-edge throughput est. +5–10% from lower inter-cell interference

V4.0

Target 2026 Q4
Engineering Changes
  • Frequency-selective feed boundaries on low band; radiating design unchanged
  • Mid-band phase shifters re-laid vertically for cleaner routing and unit-to-unit consistency
  • Simplified RET drive train (adapter and sheet-metal transmission)
RF Performance & Coverage
  • Low-band gain +0.1 dBi
  • First-sidelobe suppression +0.5 dB on all bands
  • Tighter footprint consistency across band edges

What it means: More SINR headroom mid-cell; rural cell area about +2%; less planning margin needed for band-edge coverage holes

V5.0

Target 2028 Q1
Engineering Changes
  • Cable-free phase-shifter networks on mid and high bands replace the coax harness
  • Radiating elements updated to match
  • Low-band element decoupling for cross-band isolation
  • Fewer solder joints: lower PIM risk, higher field reliability
RF Performance & Coverage
  • Mid-band gain +0.2 dBi
  • High-band gain +0.2 dBi
  • Improved low-to-mid/high-band isolation

What it means: +0.2 dB in both link directions with no beamwidth trade-off; mid-band rural cell radius about +1.7%; cleaner MIMO channel

V3.0 to V5.0: low-band gain +0.3–0.4 dBi, mid/high-band gain +0.3 dBi, first-sidelobe suppression +1.0–1.3 dB, rural coverage area +5–7%.

Sector View — Coverage & Throughput Gains

V3.0 baseline sector — shading = throughput falloff toward cell edge
Coverage gain V3.0→V5.0: area +5–7% (rural)
▲ Urban cell-edge throughput est. +5–10% from lower inter-cell interference

Illustrative single-sector geometry drawn to scale on a rural Ontario area: ≈6.00 km baseline cell radius assumption, extending to ≈6.18 km (+0.18 km) for the +5–7% coverage area gain. Not a coverage prediction. Deltas per the roadmap above.

Deltas are relative to the previous version. First-sidelobe suppression per NGMN-P-BASTA. Coverage and throughput figures are engineering estimates under typical macro-cell assumptions. Target dates are planning targets and subject to change.
