CUSTOM-MADE OEM MESH ROUTING SOFTWARE

Communication Research Labs Sweden AB provides technical development and integration services for Mesh technology. Additionally technical support for implementation and integration of wireless mesh communication.

CRL's solutions are specially developed for robust and high demanding applications. We combine extremely low power consumption and high performance making µC-CORE ideal for use in industrial automation and communication, military and tactical networks, security and surveillance.

CRL delivers OEM software solutions for a variety of different radio hardware platforms, independent whether the requirements are 443, 868, 915MHz, 2.4GHz or any other radio frequency, independent if data rate is 1.2 kbps and 2 km between radio nodes, or 250 kbps of shorter range. Product companies and system integrators can combine standard radio chips and standard DSP chips, together with their own electronics, sensors and actors or using manufacturers of their own choice.

CRLs solutions are specially developed for robust and high demanding applications. Combining extremely low power consumption and high performance it’s ideal for use in industrial automation and communication, military and tactical networks, security and surveillance.

µC-CORE can turn low power radios into IP-enabled links providing efficient interoperability between low-power devices and existing IP devices, thus paving the way for further standardization of communications. This innovative technology makes embedded devices a part of the Internet and provides uncontested advantages for chip manufacturers, OEMs, system integrators and solution providers. 

MESH CHANGES INFRASTRUCTURE FOREVER

By OEM partnership with CRL, the product companies and system integrators can combine standard radio chips and standard DSP chips, together with their own electronics, sensors and actors, using manufacturers or partners of their own choice.

FEATURES OF A µC-CORE ENABLED NETWORK

Mesh enabled communication

Each node in the network establishes the optimal path to its closest neighbor in order to reach a specific destination. Links between nodes are constantly evaluated and the network self-tunes to maintain performance, fully automatic and without need of human intervention. This might occur if for instance a node is added or removed from the network.

Micro in size and power consumption

A key attribute to achieving extremely low power consumption in a radio system is the radio software.

Low Power Mode (LPM)

Low data rate communication minimizes the power consumption and to maximizes the lifetime of the unit. Duty cycle operation can be set to 200 ms or 1500 ms in order to preserve energy.

High Throughput Mode (HTM)

High data rate communication to maximize data throughput with LPM cancellation temporarily disables the LPM duty cycle operation.

THE TECHNOLOGY BEHIND THE SOLUTIONS; THE MESH SOFTWARE FRAMEWORK

The software framework developed by CRL has a unique modular design making it possible to easily adapt the mesh implementation to varied platforms, ad hoc routing algorithms and services. The algorithms that handle the ad hoc routing/ Mesh protocol) in the mesh are all encapsulated in modules with sophisticated and dynamic interfaces that can be exchanged as plug-ins to the framework. All other functionality such as memory allocations, routing tables, QoS, security, encryption and hardware are all encapsulated in separate modules completely separated from the networking logic and mesh/ad hoc algorithms. This ensures faster customization and a more robust system, where each module in the framework is thoroughly stress tested and validated through an extensive period of time.

μC-CORE - TCP/IP COMMUNICATION:
VIRTUAL ETHERNET ADAPTER

The Virtual Ethernet Adapter is a kernel mode driver developed for both Windows XP™ and Linux 2.6 operating systems which provides pure TCP/IP communication over a radio which does not support IP communication. Interaction with the radio device can make use of either the CRL communication protocol for the µC-CORE or be adapted to use customer specific protocols.  

μC-CORE - TCP/IP COMMUNICATION: TCP/IP PROXY

The TCP/IP proxy is developed as an alternative to the Virtual Ethernet Adapter. The proxy is developed as a user space application, with kernel space interaction, which intercepts TCP/IP sessions and creates transparent TCP/IP tunnels allowing TCP/IP communication over a none-IP radio. The proxy software is intended for existing applications/ systems solutions where the source and/or destination of the communication path cannot be altered. Interaction with the radio device can make use of either the CRL communication protocol for the µC-CORE or be adapted to use customer specific protocols
