Linx Technology HumDT™ is built on the Hummingbird platform and is designed for reliable wireless digital data transfer. It broadcasts at 900MHz and features a frequency agile protocol which repeats the packet on up to 4 channels, gaining some of the noise immunity of frequency hopping without the synchronization, timing delays and other overhead associated with FHSS solutions. The number of channels is configurable as well as which channels are used. The module automatically handles all of the over-the-air transactions, so no overhead is required by the user. The HumDT™ transceiver has built-in networking. Each module can act as one of three components in the network, either the Access Point that controls a network, a Range Extender to repeat messages and expand the range of the network, or an End Device. Each Access Point can be joined to up to 50 Range Extenders and End Devices. The Access Point also supports routing so that End Devices can talk to each other through the Access Point. All routing and network maintenance functions are automatically handled by the module.
