RFAPCO-25 vs APCO-16: A Detailed Comparison
Advertisement
This article compares APCO-25 and APCO-16, highlighting the key differences between these two technologies.
APCO-16
APCO-16 defines the operational and functional requirements for trunked radio systems. Think of it as the blueprint for how a public safety communication system should work. It’s an older standard, established in 1979 by the Association of Public Safety Communications Officials (APCO) - Project 16.
Examples of systems built using APCO-16 include Motorola’s SmartNet and SmartZone trunked systems. EF Johnson also has products based on this standard.
APCO-25
APCO-25, or Association of Public Safety Communication Officials-Project 25, is a digital radio standard primarily used in North America. It’s specifically designed for two-way radio communication for public safety and emergency services.
Currently, APCO-25 supports two voice channels within a single 25 KHz RF channel. This allows for more efficient use of the radio spectrum.
Key Differences: APCO-16 vs. APCO-25
The following table summarizes the main differences between APCO-16 and APCO-25:
| Specifications | APCO-16 | APCO-25 |
|---|---|---|
| Technology | Analog | Digital |
| Multiple Access | FDMA | FDMA |
| Telephony Type | Trunked | Conventional & Trunked |
| Channel Bandwidth | 25/30 KHz | 25/12.5 KHz |
| Frequency Range | VHF (136-174 MHz), UHF (403-512 MHz), 800 MHz Bands | VHF (136-174 MHz), UHF (403-512 MHz), 800 MHz Bands |
