Amateur (Ham) Radio Simplex Frequencies
An FCC Amateur Radio license is required to transmit. Privileges expand with license class.
Technician Class Privileges (VHF/UHF+)
| Band | National Calling Freq (MHz) | Notes |
|---|---|---|
| 6 Meter | 52.525 | FM Simplex |
| 2 Meter | 146.520 | Most popular simplex calling channel |
| 1.25 Meter | 223.500 | Less common, quieter band |
| 70 cm | 446.000 | Excellent for urban environments |
Technicians also have limited privileges on some HF bands.
General Class Privileges (HF)
Includes all Technician privileges plus access to worldwide HF bands.
| Band | Common Voice Simplex Range (MHz) | Primary Use |
|---|---|---|
| 80 / 75 Meters | 3.800 - 3.900 | Regional communication, best at night |
| 40 Meters | 7.175 - 7.225 | Medium-to-long distance, day & night |
| 20 Meters | 14.225 - 14.300 | Long distance (DX), best during the day |
| 17 Meters | 18.130 - 18.168 | Similar to 20m, daytime DX |
| 15 Meters | 21.300 - 21.450 | Daytime DX, dependent on solar cycle |

| 10 Meters | 28.300 - 28.500 | Long distance when band is open |
Amateur Extra Class Privileges
Includes all General privileges with expanded spectrum on all bands. Refer to a full ARRL band chart for specific frequency allocations.
Wi-Fi Network Standards & Frequencies
| Standard | Common Name | Frequency Band(s) | Key Characteristics |
|---|---|---|---|
| 802.11 | Legacy | 2.4 GHz | Original standard (1997), slow speeds (1-2 Mbps). Obsolete. |
| 802.11a | Wi-Fi 2 | 5 GHz | Faster than 'b' but shorter range. Not widely adopted initially. |
| 802.11b | Wi-Fi 1 | 2.4 GHz | First widely adopted standard. Prone to interference. |
| 802.11g | Wi-Fi 3 | 2.4 GHz | Improvement on 'b', backward compatible. Still common in older devices. |
| 802.11n | Wi-Fi 4 | 2.4 GHz / 5 GHz | First dual-band standard, introduced MIMO for better performance. |
| 802.11ac | Wi-Fi 5 | 5 GHz | Significant speed increase over 'n'. The most common standard in use today. |
| 802.11ax | Wi-Fi 6 / 6E | 2.4 / 5 / 6 GHz | Focuses on efficiency in crowded networks (OFDMA). 6E adds the 6 GHz band. |
| Specialized Standards | |||
| 802.11ah | HaLow | Sub-1 GHz (900 MHz) | Long range, low power, low data rate. Ideal for IoT sensors and devices. |
| 802.11s | Mesh | 2.4 / 5 / 6 GHz | Defines how wireless devices can interconnect to create a mesh network. |
| 802.11ad | WiGig | 60 GHz | Extremely high speed, but very short range and cannot penetrate walls. |
| 802.11p | WAVE | 5.9 GHz | Wireless Access in Vehicular Environments. For car-to-car comms. |
