ONE-NET uses UHF ISM radio transceivers and currently operates in the 868 MHz and 915 MHz frequencies with 25 channels available for use in the United States. The ONE-NET standard allows for implementation on other frequencies, and some work is being done to implement it in the 400 MHz and 2.4 GHz frequency ranges.
ONE-NET utilizes Wideband FSK (Frequency-shift keying) to encode data for transmission.
ONE-NET features a dynamic data rate protocol with a base data rate of 38.4 kbit/s. The specification allows per-node dynamic data rate configuration for data rates up to 230 kbit/s.
ONE-NET supports star, peer-to-peer, and mesh networking topologies. Star network topology can be used to lower complexity and cost of peripherals, and also simplifies encryption key managemnt. In peer-to-peer mode, a master device configures and authorizes peer-to-peer transactions. Wireless mesh network mode allows for repeating to cover larger areas or route around dead areas.
Outdoor peer-to-peer range has been measured to over 500 m, indoor peer-to-peer range has been demonstrated from 60 m to over 100 m, and mesh mode can extend operational range to several kilometers.
Simple, block, and streaming transactions are supported.
Simple transactions typically use message types as defined by the ONE-NET protocol to exchange sensor data such as temperature or energy consumption, and control data such as on/off messages. Simple transactions use encryption techniques to avoid susceptibility to replay attacks.
Block transactions can be used to transmit larger blocks of data than simple messages. Block transactions consist of multiple packets containing up to 58 bytes per packet. Blocks transactions can transfer up to 65,535 bytes per block.
Streaming transactions are similar in format to block transactions but do not require retransmission of lost data packets.
ONE-NET is optimized for low power consumption such as battery-powered peripherals. Low-duty-cycle battery-powered ONE-NET devices such as window sensors, moisture detectors, etc. can achieve a three to five year battery life with “AA” or "AAA" alkaline cells.
Dynamic power adjustment allows signal strength info to be used to scale back transmit power to conserve battery power. High data rates and short packet sizes minimize Transceiver On time. Further power efficiency can be gained utilizing deterministic sleep periods for client devices.
By default, ONE-NET uses the Extended Tiny Encryption Algorithm (XTEA) version 2 with 32 iterations (XTEA2-32). The ONE-NET protocol provides extensions to even higher levels of encryption. Encryption is integral to the ONE-NET protocol, there are no unencrypted modes. Alternate encryption ID tag allows extension to stronger algorithms.
Security key update rate can be set on a per-system basis to allow greater control of security level - faster key updates increase network security.
Programmable “still operational” messages can be used to detect sensor tampering or device failure.
ONE-NET works on a number of transceivers from manufacturers such as TI, Analog Devices, Semtech, RFM, Integration and Micrel. Transceivers that have been tested as working with ONE-NET include:
Simple ONE-NET devices such as motion sensors have modest host processor requirements:
ONE-NET is available to use for free using an open source license. ONE-NET uses the OSI-approved “Simplified BSD License” which is one of the so-called permissive free software licenses.
ONE-NET website provides a variety of open source community-supported resources including:
A number of companies have announced support for the ONE-NET open source initiative including:
