Dallas, Texas-based
RF Monolithics, Inc., a provider of solutions-driven, technology-enabled wireless connectivity for a broad range of wireless applications,
announced that it has
augmented its machine-to-machine portfolio of wireless communications products with the version 2.0 release of a firmware upgrade for its DNT series of 900 MHz and 2.4 GHz proprietary frequency hopping spread spectrum "FHSS" RF modules.
RF Monolithics' DNT series modules are not only cost-effective but also have high degree of configurability that include a selection of configurable over-the-air data rates and transmit power levels which allow one module to work for many products.
The version 2.0 firmware upgrade features new software-configurable Tree-Routing with fail-over. With this upgrade, designing and maintaining of FHSS wireless sensor networking applications is much easier now. In addition, the size of FHSS WSN networks can now be extended to a virtually unlimited number of nodes, says RF Monolithics.
With Tree Routing, any node can be a routing node through software configuration. In addition, virtually unlimited number of nodes can join the network. Any node that loses its parent can automatically find and join a new parent.
Tim Cutler, director of M2M products, said, 'The firmware upgrade not only extends range through an intuitive tree routing scheme, but also addresses a weakness of many tree routing systems, single points of failure, by adding a fail-over capability. The DNT series tree routing gives OEMs the path redundancy of a true mesh network without the complexity and increased latency seen in mesh networks.'
Company officials said in the release that Tree-Routing eliminates the need for dedicated routing nodes. Even, networks can be configured 'on the fly' to turn nodes into routing nodes through over-the-air configuration commands. This allows network coverage to be extended as required after the network is commissioned.
Compatible with firmware versions that have already installed in the field, the version 2.0 can be used to upgrade all DNT2400 modules in the field and all DNT900C modules. All DNT900P modules revision H or later can also be upgraded to the 2.0 firmware.
Customers currently leveraging any of the above DNT series modules can download the firmware Version 2.0 upgrade from the modules technical support section of the RFM
website.
In the recent news,
IoTevolutionworld reported that RF Monolithics has released the 11Mb/s version of its Battery-Powered Wi-Fi Module, WSN802G, which is a 2.4 GHz IEEE 802.11g radio transceiver module.
