Phoenix Contact Radio Line

Licensed vs Unlicensed radios Industrial serial and Ethernet radios that are licensed commonly use frequencies within the range of 150-470 MHz. The advantage of using these frequencies is that there would be less interference from other sources. There is less terrain signal loss, better line of sight, lower signal loss through connectors and cables and a greater overall range. Unlicensed industrial serial and Ethernet radios use 900 MHz, 2.4 GHZ and 5.8 GHz frequencies. The advantages for these frequencies are that they are larger bandwidths allowing higher data rates and WiFi access for third-party devices. However, there are some disadvantages. There is a reduced range, with the power and frequency limited by the FCC and there is a lower tolerance of line-of-site obstructions.

Phoenix Contact radios are available as licensed, unlicensed, cellular and I/O radios that work with either 12 VDC or 24 VDC power sources. They have options for point-to-point and point-to-multipoint setups. Phoenix industrial wireless solutions include models with 400 MHz, 900 MHz, or 2.4 GHz frequencies. The Phoenix 2.4 GHz ethernet radios have a range of 10 miles (16 km) and the Phoenix I/O radios have a range of 5 miles (8 km) and offer a 500 Kbps data rate. 

Phoenix Contact Radioline wireless radios are ideal for large systems. The Radioline system transmits data and signals over several kilometers with devices available with a wide range of frequencies. Radioline transmits IO signals as well as serial data and is therefore very versatile. Data transmission is reliable and secure utilizing frequency hopping spread spectrum (FHSS) and encryption according to advanced encryption standard (AES).
