The launch of the wiConnect RM Lite and wiConnect RM Pro radio modems is a subject of interest for the technical industry, especially after the European Community allocated funds with a view to enhancing the performance of Short Range devices and Industrial Scientific Medical bands. In Fact, wiConnect RM Lite and wiConnect RM Pro design has been financed by EC FP7 program as communication subsystems of EcoThermo building automation and energy saving system. The two radio modems were especially created to allow the installation of wireless communications capability also for third party devices and stand out through several features that bring a considerable contribution on a market that till a decade ago was just a niche and nowadays with the emerging concept of Internet of Things is having an exponential growth. These two short range wireless devices, with ultimate capabilities and innovations, have a variety of applications for many types of industries and it is estimated that in the future they will be an integrated part of everyday life, not only at an industrial and commercial level, but also at a residential one. Here are some basic technical details about each of these radio modems. To begin with, the wiConnect Radio Modem Lite is a short range radio modem (or radio transceiver) that, in spite of its miniature look, offers many building automation benefits, especially in terms of quality of radio link, configuration capabilities and power consumption. The manufacturer made this device available on multiple bands: 868MHz, 433MHz and 915Mhz, but other frequencies may become available for custom designs. It can be used for remote control communication and it also comes with a microcontroller that streamlines the configuration process with few incredible easy to use AT commands. wiConnect series radio modem has been designed to be the top performances product of its category. It has a maximum receive sensitivity of -126 dBm, could be set to works not only on 2-GFSK modulations, but also on 4-GFSK saving on band occupation. Besides, it double the maximum data packets length with respect to other modem (up to 250 bytes), increase the date rate up to 230kbps without buffering at RX and TX side, and work with different bandwidth schema for a best match between data rate and available channels. The configuration interface works on AT commands and wiConnect modem are characterized by very low consumption. It is important to mention the contribution of the wiConnect RM Lite USB, which enables the connection between devices adopting wiConnect radio modem and laptops or desktop computers. Despite its advanced features, this radio modem is available at an affordable cost. Finally, a great innovation for this modems segment introduced by wiConnect modems is the antenna diversity: this technique mitigate the bad effect of the multipath fading that mostly affect the indoor radio communications making them less reliable. Additional information regarding the full technical specifications is available online, on the manufacturer website and there are also several user guides that give extensive instructions on how to install and control the device. The wiConnect RM Pro is based on the Silabs 4461 RF IC, it works on the same frequencies as the Lite version. It is easy to configure based on the instructions provided in the user manual and, if clients prefer, they can choose several optional features, such as a flash memory, RTC and RF connectors. FwiConnect RM Pro offer a series of peripherals controllable by easy AT commands such as UART, SPI, I2C, Timers, Awaking Function and Interrupts, micro power pulse counter, PWM and GPIO. Both this device and the Lite version can be tested, configured and connected using an evaluation kit that include an easy to use software with statistical and graphical capabilities. Those who are interested in these two devices and want to find out more about other related products should also read about the test software tool for the radio modems. All in all, the wiConnect RM Lite and wiConnect RM Pro radio modems are two radio transceivers that set new standards in the wireless systems industry and that change the way building automation is perceived at an industrial and residential level. They can be used in the military, energy, security and transportation fields and, as time passes, technicians find even more benefits that place radio modems and Internet of Things servers in general at the forefront of technology.
