Wireless Modules Make Broadband M2M Connections

May 13, 2014
These broadband modules enable high-speed links for control, surveillance, and telemetry.
Each WavePoint 10e module supports multiple frequencies and can be used for as many as four WavePoint radio modules.

Data is increasingly important for modern society, for management of utilities, oil and gas services, government, military functions, and many other segments of life, and access to data must be reliable and often broadband. Communications now is often between machines as well as humans. To provide such access, the WavePoint wireless-communications modules from FreeWave Technologies are designed to provide machine-to-machine (M2M) wireless communications while operating within a customer’s choice of unlicensed frequency bands at 900 MHz, 2.4 GHz, and 5.0 GHz. These compact radio modules employ orthogonal-frequency-division-multiplex (OFDM) technology to achieve data rates to 200 Mbytes/sec using secure communications based on standard Ethernet and Internet protocols.

WavePoint base modules (see photo) provide a choice of frequency range based on a customer’s needs, with excellent propagation characteristics at the lowest frequencies (900 MHz), worldwide availability in the middle frequency range (2.4 GHz), and generous capacity at the highest frequencies (5 GHz).

WavePoint building blocks include the WavePoint 10e unit, which supports multiple frequency bands and can be configured for as many as four internal WavePoint radio modules, and the single-radio, single-frequency WavePoint 20e unit, for installation at remote end points. The WavePoint 10e can also be used as a relay point in a M2M network or as a Wi-Fi hotspot for a variety of different wireless-communications applications. The WavePoint 10e integrates a pair of RS-232 ports, one RS-485 port, a micro-Universal-Serial-Bus (micro-USB) port, and four RJ-45 Ethernet ports for flexible communications interfaces. The WavePoint 20e, although it contains no micro-USB or serial ports, is equipped with an Ethernet port with power-over-Ethernet (PoE) capability.

These radios allow the establishment of seal-healing M2M networks with interconnectivity to link to existing communications systems. They are highly secure, based on security protocols using the Advanced Encryption Standard (AES).
