LiteMesh® is Liteplan's wireless emergency lighting operating system gathering data from DALI compliant emergency lighting modules. The system creates a secure, robust mesh using IQRF long range mesh technology.

The data is the sent via the cloud to a browser based user interface portal. This portal features floor plans of the building showing the exact location of each emergency light fitting or exit sign. As the DALI control gear carries out its functionality tests on a monthly basis and duration tests on an annual basis, compliance reports are generated through the portal. These reports can be sent to various individuals, but are also securely held for a five year period. In addition to this, real time fault reporting is also generated, indicating what needs to be replaced and exactly where it is, allowing for a first time, first fix resolution.

One of the main features of the system is the customer led commissioning tool. This strong, contractor friendly tablet, features our amazing LiteWork® software that allows the scheme to be commissioned in a fraction of the time of traditional systems. Each light fitting is placed onto the floorplan as it is discovered on the network and once this plot has been completed, the information is sent directly to the portal via the cloud.

Grouping and scheduling of emergency lighting tests is handled via the portal user, minimising time spent on site.

As LiteMesh® operates with the IQRF wireless protocol, the system can also incorporate other IQRF Alliance members' product. For example, if one needed to monitor temperature, air quality, footfall, drain levels etc. there will be Aliance members that are experts in those respective fields that will be able to help. This can be the beginning of the journey into a complete holistic smart building.

Specifications

• Scalable from Small Schemes to Large Installations
• Compatible with any Manufacturer's DALI Control Gear
• Compatible with Other IQRF Alliance Products
• Simple Installation and Commissioning Process
• Robust and Secure Mesh Technology

The LiteMesh network uses the IQRF protocol. This features mesh hopping capability. A secure, scalable and resilient mesh network. The network becomes stronger, the more it grows.

Technical Mesh Data:

IQMESH® routing protocol utilising optimised directional flooding brings outstanding network robustness

IQRF® DPA commands (a standardising language) assure simple integration and interoperability

OTA (Over-The-Air) service enables remote centralised network management lowering maintenance costs. All network communication is encrypted with AES-128.

Multilayer security based on industry standard 128-AES is extended by dynamic keys generation and exchange which makes wireless communication significantly more immune to cyber-attacks.

FRC® (Fast Response Commands) dramatically increases network throughput and reliability.

SW: OS + DPA + Appl. + SDK

Band: 433 / 868 / 916 MHz

Network topology: Mesh

Range (device to device): 500+ meters line of sight, up to 100 meters within a building.

Range (device to gateway): Tens of kilometres

Native multi-hop: 240 hops per packet

Routing algorithm: Optimised directional flooding

Security: Multilayer, AES-128, dynamic keys

Directionality: Bi-directional

End Devices OTA Management: for all operations needed

Main benefit: easy adoption / reliability

LOW POWER

With 240 hops and robust routing, IQRF® is the best fit for large control applications, such as street lighting, emergency lighting or parking, where reliability and security is a must.

Each mesh hops data to the gateway which then reports to the cloud platform which can be viewed at any location via a web browser. The gateways are persistent without communication. Therefore, if for any reason communication is lost, data is held at the gateway until the signal is re-established.

LiteMesh can be supplied with either a basic gateway or with features IA Connects' Mobius Flow gateway, which transmits data to the user interface portal. It can accept sensor and actuator data from any source such as OPC UA / BACnet / DALI / EnOcean / Analog / Digital etc. This will offer the ultimate in future proof scale-ability potential.
