Data Radio Modems
Wireless modems are used to send data between two or more locations. Raveon's long range VHF data radios and UHF data radios are capable of communicating up to 100 miles, with typical distance in the 10-40 mile range.
The data the Raveon modem communicates may be telemetry signals from a transducer, remote control signals, computer communications, GPS position, or a host of other digital messages.
Various Input/Output connectors are available including USB, RS232, RS485, RS422, and digital logic levels.
Raveon designs its data radio modems with 32-bit micro-processors enabling these products with more features and capabilities than most any other radio modem.
Long Range (Achieved through high-performance RF and base-band design)
- Raveon products are designed to commercial, industrial, and military standards.
- Low-cost consumer-grade components or designs are never used in Raveon data radio modems.
- 100% of the design work is done by Raveon Technologies here in the USA.
- Raveon designs the RF circuits so that they excel in RF performance, and will work reliably in the presence of interfering signals and strong nearby carriers.
- Our DSP modem is optimized to recover data in the presence of noise, which greatly increases the reliablity in the fringe reception areas.
Easy to Use (Achieved through user-friendly interface and very powerful commands)
- Configured via command-line interface or using free RadioManger software.
- Front Panel status LEDs all users to monitor operation at a glance.
- CRC, ID codes, and packet-protocol make using it plug-and-play.
- Basic setup: Serial data goes in one modem. Same serial data comes out other modem.
- Advanced setup: Users may configure radio IDs, repeater function, serial port timing, I/O parameters.
- Large buffers allow over-the-air data rates to be independent of serial-port rates.
- Raveon will gladly pre-configure your radio modems for your specific system.
Easy to Install and Maintain (Achieved through built-in and remote diagnostics)
- Small size.
- Built-in USB, RS232, RS485, or RS422 I/O connections.
- Over the air diaganostics, ping, and system monitoring.
- Able to read the Radio Signal Strength (RSSI) over-the-air for remote diagnostics.
- Wide DC input operational voltage range.
Reliable (Achieved through design excellence and quality manufacturing)
- Single-board construction. Less connectors and higher performance.
- Conservative commercial/industrial design.
- Bullet-proof firmware. Never will a modem "lock-up", freeze, or stop running.
- No internal components are ever operated near their limit.
- Efficient green design. Low DC power consumption using modern-efficient CPUs
- Low overall power consumption keeps the unit running cool.
Data vs Voice
Traditional two-way radios are analog, and were designed for voice communications. Early data radio modems were voice radios integrated with a telephone-modem to create a digital radio link. These were very slow and expensive, and some data radios today say they are data radio modems, but are still built with this old analog approach.
Raveon's data radio modems are designed from the ground-up as data radio modems. They have a UHF or VHF radio transciever in them, which is optimized for data. They contain a DSP based modem processor that encodes and decodes data using high-speed modulation techniques, and an intelligent microcontroller that gives the product a rich set of features.
What is a Data Radio Modem?
So what makes a radio a "Data Radio Modem"? There are a few very important features to look for:
- High speed. High speed RF synthesizers. High speed data rates. High speed serial ports.
- Digital Processing. Digital signal processing allows the product to store-and-forward repeat; error correct, automatically key on data, buffer messages, check CRC codes, and identify radios.
- Flexible Radio IDs. Data radios must work in conjunction with dozens if not hundreds of other radios. 16 bit IDs, group codes, repeater routing tables, and address masks allow a user to create sophisticated radio networks.
Can't I Make My Own Radio Modem?
The short answer. No. The FCC (nor any other regulatory body) does not allow data communications using a voice radio. The only exception to this would be to connect an external modem to the microphone input of a voice radio. This may be allowed, but you would soon find that the system performance using of this type of approach would be terrible.
Can you connect a modem to the AUX input or a radio module? No. Some voice and low-cost radios provide inputs and outputs that could be connected to an external modem and make a reasonable data radio combination. But, this will violate the FCC certification of the product. A radio modem is certified by the FCC, IC, or for CE compliance as a complete system. There is no provision for changing any portion or using an external modem on the AUX input. The fines for violating FCC regulations can be severe, and the liability of installing a complete data radio system based upon un-authorized radio configurations can be substantial.
Don't try to take short cuts. Besides the potential FCC violations, they will cost you more in the long run. Raveon's data radio modems are the most economical data radios on the market. Our complete integrated solutions will cost you less and work better than trying to patch together a radio system using brand X radio and brand Y modem.
