NIST-recommended link security
Nivis marries its open standards software stack with Freescale’s Kinetis radio module to provide a high quality radio node that can be incorporated into wide range of sensing and control devices.
Nivis offers its industry leading radio node software stack either bundled with the physical device or separately.
The Nivis implementation is IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) compliant, insuring inter-operability with a large number of other hardware and software suppliers. Nivis employs IPv6 Routing Protocol for Lossy and Low-Power Networks (RPL), to drive down power requirements and maximize battery life.
+ 6LoWPAN compliance, the de factor standard for low cost, power constrained devices, insures interoperability, reduces power use and extends battery life.
+ Enhanced RPL support increases reliability, reduces power consumption and improves network routing efficiency
+ NIST-recommended link security secures communications at the link level, mandatory for most applications
+ CoRe/REST compliance implements web services all the way to the node so that smart objects can be accessed from any browser
+ PHY support for 868 MHz band permits marketing and deployment in Europe.
+ Scalability (up to 3,000 devices per gateway at present) permits cost effective deployment of very large networks
