Overview

Cellular and Short-Range Solutions from a Single Source Being the only M2M supplier worldwide to offer all relevant wireless technologies in its product portfolio, Telit provides its customers with tailored, single source solutions. In 2008, Telit made a strategic move from a "cellular M2M" solutions provider to a "wireless M2M" solutions provider, including both GPS|Glonass and Short Range RF technologies in its product offering. The company develops, manufactures and markets a wide range of enterprise communication modules:

Short-Range Technologies

  • ZigBee

  • Short Range RF (proprietary mesh/point-to-point for unlicensed frequency bands)

  • Short Range to GSM/GPRS

  • Wireless MBus

Short Range

The m2m field is changing rapidly, and this market is becoming mature. New complex m2m applications may require multiple wireless technologies and competences. When a machine enabled with wireless connectivity requires extremely low cost/capacity batteries, a cellular based module is not a viable solution due to intrinsic technical and economical reasons. All m2m applications that present these requirements can be successfully connected using low-power high efficiency short range radio frequency (RF) devices. The Industrial Scientific and Medical (ISM) license-free frequency bands (433, 868, 915 and 2400 MHz) are best suited for these applications. Here is where the IEEE 802.15.4, ZigBee® and proprietary, point to point, star and mesh network based applications can provide a cost effective solution for meeting m2m connectivity requirements.

Telit understands the market requirements and the sizable opportunity, on October 30, 2008, Telit completed the acquisition of One RF Technology SaS, a small but highly skilled wireless technology company based in the high tech area of Sophia Antipolis, Cote d'Azur, France. Thanks to this acquisition, Telit gained long-term experience in short range technologies, full ownership of Intellectual Property Rights (IPR) on three different protocol stacks (point-to-point/star network, low power mesh, and fully certified ZigBee®) and can offer an unparalleled product portfolio that is integrated with the three new short range product lines including 10 short to mind range modules, 4 terminals plus dedicated evaluation kits and accessories.

Telit partners can now design dedicated wireless area networks and even connect with a cellular concentrator for remote management. As usual, Telit is focusing its attention on the Total Cost of Ownership (TCO) reduction, providing unattended ROI as a competitive advantage.

All of the Telit short range devices include in-house developed protocol stack for star, point-to-point and low power mesh network communication, but also standard communication technologies such as ZigBee® Pro and Wireless M-bus with guarantied interoperability with other devices supporting the same standard.

 

Wireless M-bus is based on European standard EN 13757-4 for data exchange on remote meters (S, T and R modes) and EN 13757-5:2008 extension of part 4 that specifies additional routing in order to reach bigger distances (R2 and Q mode) on 868MHz. On the application level Telit is compliant with Dutch profile NTA8130 and OMS and supports AES encryption.

ZigBee® PRO compliant protocol stack is developed by Telit expertise that are among the front-runners in ZigBee® technological know-how and low-power wireless Mesh network development. Telit also provides standard ZigBee® alliance profiles, custom Zigbee® profiles, full support and training during product design.

Star Network Stack is the best solution for ultra low power and low latency time applications that require point-to-point or multipoint (broadcast) network communication and simple plug and play protocol for RF communication typically used to replace communication over cable. Due to a very low latency time, the characters will be transmitted to the radio link as they are sent to the serial link and any kind of collision can be avoided with LBT (listen before talk) feature, while for better network planning RSSI level measurements can be used as a simple indicator of signal strength. Proprietary Star Network protocol stack running on LE module family can be used in transparent mode (plug&play, minimum latency), address secured (nodes with ID number, data can be addressed to a specific mode), with telemetry or download over the air mode (remote re-flashing of the modules).

Low power Mesh is Telit proprietary protocol with the cluster-tree network structure. Power management can be done on both routers and end nodes with extreme flexibility in setting different synchronous network times, data rates or message formats. The same parameters also influence the network latency giving full freedom to the OEMs to program it according to the system requirements. Optimized power consumption can be achieved on a network with small data quantities sent periodically, while high data through put will speed up the network data exchange and increase consumption. Auto-repair, auto-association, up to 10 hops on the network and 10,000 devices make it easy to integrate in a stabile solution.
