| VHF narrowband radio | 30–300 MHz Common public allocations: approximately 136–174 MHz | Wide-area voice, maritime, utility, and field communications | 6.25–25 kHz | 1–50 W conducted | 0–6 dBi | 5–30 km, terrain dependent | 96 dB at 150 MHz and 10 km | Approximately 15–30 dB | Frequency licensing, antenna height, ground conductivity, and regional channel spacing are critical. |
| UHF land-mobile radio | 300 MHz–1 GHz Common professional ranges: approximately 400–520 MHz | Business, industrial, public-safety, and campus communications | 6.25–25 kHz | 1–50 W conducted | 0–8 dBi | 3–20 km, urban and indoor loss dependent | 106 dB at 450 MHz and 10 km | Approximately 10–25 dB | Check national allocation tables, emission masks, antenna connector requirements, and duty-cycle limits. |
| Sub-GHz data radio | 433, 470, 780, 868, and 915 MHz regions | Telemetry, remote monitoring, industrial sensors, and low-power control | 7.8 kHz–500 kHz | 10 mW–1 W typical, region dependent | 0–5 dBi | 1–15 km open outdoor paths | 112 dB at 915 MHz and 10 km | Approximately 8–25 dB | 868 MHz and 915 MHz rules differ by country; verify EIRP, bandwidth, listen-before-talk, and duty-cycle requirements. |
| 2.4 GHz wireless data device | 2.400–2.4835 GHz in many regions | Short-range data, industrial control, local networking, and machine connectivity | 1–80 MHz, technology dependent | 1–100 mW typical for low-power devices | 0–8 dBi | 10–300 m typical indoor/outdoor | 114 dB at 2.4 GHz and 5 km | Approximately 5–20 dB | Interference from other 2.4 GHz systems, enclosure loss, antenna orientation, and regional EIRP limits affect performance. |
| L-band satellite or GNSS receiver | 1–2 GHz Many satellite navigation signals are near 1.1–1.6 GHz | Positioning, timing, asset tracking, and satellite data reception | Hundreds of kHz to several MHz | Receive-only or low-power uplink | 0–35 dBi, antenna dependent | Satellite visibility or several-kilometre terrestrial links | Approximately 126 dB at 1.575 GHz and 10 km | Depends strongly on receiver noise figure and processing gain | Assess sky visibility, regional satellite service availability, interference protection, and antenna ground-plane requirements. |
| S-band broadband radio | 2–4 GHz Common systems operate around 2.3–2.5 GHz or 3.3–3.8 GHz | High-throughput fixed links, private networks, robotics, and video telemetry | 1–100 MHz | 100 mW–10 W conducted | 3–24 dBi | 0.5–20 km line-of-sight | 114 dB at 2.4 GHz and 5 km | Approximately 10–25 dB | Requires careful channel planning, Fresnel-zone clearance, antenna alignment, and local spectrum authorization. |
| C-band fixed wireless link | 4–6 GHz Specific allocations vary considerably by country | Point-to-point backhaul, private networks, and professional telemetry | 5–100 MHz | 100 mW–10 W conducted | 15–35 dBi with directional antennas | 1–30 km line-of-sight | 114 dB at 5.8 GHz and 2 km | Approximately 15–30 dB | Rain attenuation is usually lower than at much higher microwave bands, but licensing, antenna separation, and interference coordination remain important. |
