8 IQRF Networks IQRF is a technology intended for wireless networks. Built-in IQRF operating system supports many ways to reach different needs of different wireless applications - from easy point-to-point communication to huge mesh networks. Range Range depends on many parameters, e.g., on output power, bitrate, antenna type, terrain, signal modulation and as well as on software techniques. Network topologies There are two ways to extend communication range: Brute force increasing RF output power. It leads to higher consumption and noise. Moreover, RF signal sometimes cannot pass through an obstacle even with high RF output power. With hop-by-hop routing transfer via network devices, which is essential for mesh networks. There are many network topologies, most of them are supported by IQRF OS. This is an overview of some typical examples: Point-to-point A wireless link between two nodes, it is often used in remote control. IQRF Smart Transceivers utilizing bidirectional communication provide much higher performance, reliability and security compared to standard unidirectional systems. Range is based only on physical parameters of transceivers. Star In wireless networks with star topology, each network node has a wireless link to the network coordinator. The popularity of star networks is based on implementation simplicity. It is an ideal choice for systems working in 'non-obstacle' environments, e.g. for voting systems. With limited range and no routing capabilities it is not very convenient for systems where robustness and stability should be assured. Tree Mesh Chain-mesh 8 In hierarchical network topology, every node is connected to its parent node that is one level higher in the hierarchy. A coordinator is on the top level of the hierarchy. With traversing via parents each node can send messages to the coordinator in minimum hops. Tree topology is automatically created during discovery. Unlike the mesh network, communication fails, if any one node fails. Due to the alternative paths, mesh network topology is the most reliable topology for wireless networks. IQRF uses oriented flooding based on TDMA, assuring high resistance against local failures caused by interference or temporary node unavailability. For failure immunity and physical communication range extension, the mesh topology network is the ideal choice for any application demanding reliability. Mesh is the most reliable network topology. A variation of a partially connected mesh network topology is often found, e.g. in street lights, where single lights can be seen in lines, but due to the higher communication range, compared to the physical topology, each light-node can have more than two links. For its reliability, it is an ideal choice for street lighting applications.

9 IQMESH Open Protocol IQRF smart transceivers implement light but efficient built-in IQMESH protocol supporting either simple wireless connectivity or even complex networks. It includes sophisticated features, but despite the complexity and performance, IQMESH is extremely easy to use. Powerful OS functions easily allow tailoring of IQMESH functionality to specific needs of given project. Routing algorithm highly impact performance and reliability of any network communication. IQRF routing The goal of packet routing in target applications is to reliably and efficiently deliver data over the network. In IQMESH based networks, the flooding mechanism is primarily used. Virtual Routing Structure (VRS) created during discovery is directionally flooded. The network would be flooded from the coordinator to the node for all control purposes or from the node to the coordinator for data collection. A special order of VRS together with TDMA enables a directional, efficient and collision free flooding mechanism. The network routing mechanism is illustrated below: C R1 N5 N1 R2 R4 N2 N4 R3 Frame N3 R5 C R1 N1 R2 N5 R4 N2 N4 R3 Frame N3 R5 C R1 N5 N1 R2 R4 N2 N4 R3 Frame N3 R5 C R1 N1 R2 N5 R4 N2 N4 R3 Frame N3 R5 C R1 N1 R2 N5 N2 N4 R3 R4 Frame N3 R5 1 Coordinator Node Reached node Active node (TX) Available link Activated link Active time slot IQRF supports in a user-friendly way various routing algorithms fitting different network topologies - P/ P, star... mesh - and utilizing their specific advantages (e.g., low time latency in simple network topologies and high reliability communication in mesh networks). A specific routing algorithm is chosen in the application based on required efficiency and purpose simply by setting one system variable. Routing based on network logical address, tree routing to the coordinator and routing based on discovered Virtual Routing Structure are three basic routing schemes supported by IQRF OS. Addressing in the network is realized via the logical network address obtained during bonding which is one byte long or via a two byte user address dedicated by the user. Straightforward implementation enables programmers to stay focused on their application code not to network functionality, resulting in much faster application development. 9

10 IQRF Interfaces There are many ways to connect IQRF to rest of the world. Although IQRF is primarily designed for RF and networking, even standalone smart transceivers are able to perform surprisingly complex tasks. Smart transceiver interfaces Besides RF connectivity, standalone IQRF transceivers have many interfaces: Standard interfaces 2 SPI, I C, UART Peripherals I / O, PWM, pulse generator ADC, DAC, analog comparator,... All above mentioned interfaces are supported by IQRF OS or an embedded processor. Other interfaces 1-Wire and other interfaces can be easily programmed into application software Ready to use examples are available The following diagrams show only some possibilities.

11 IQRF Gateways IQRF gateways Specialized IQRF gateways using more complex interfaces (USB, Ethernet, GSM,...) are available.
