Thread is a wireless protocol designed for the Internet of Things to simply and securely connect devices in the home to each other and the cloud. Thread is a mesh network designed to surely and reliably connect hundreds of products around the home, without blasting though battery life.Thread uses standard 802.15.4 radios and adapts the same Internet Protocol (IP) that is used by the Web. Adding features like mesh networking, multiple border routers, direct address-ability from the Internet, no single point of failure and the ability to cope with changing network conditions makes the system extremely robust.
Linx Technologies’ Raven Platform
The Raven™ Transceiver Module
The Linx Raven™ Series Transceiver module consists of an 802.15.4 RF transceiver paired with a microcontroller. Unlike competitive Thread modules that run on modules designed for Zigbee®, Linx specifically designed and optimized Raven™ to run proven 6LoWPAN / IP-based protocol stacks, such as Thread.
- Dual crystals provide highly accurate wake-up timing for sleepy end devices
- 16.5 mm by 25.7 mm for space-constrained designs
- Latest generation silicon: provides best-in-class standard link budget (-110 dBm) and sufficient memory (512k flash) to run Thread and applications stacks
- Multiple RF output options:
- on-board chip antenna
- u.FL connector
- castellation connection for PCB antennas
- FCC and Industry Canada modular approval (pending) and meets ETSI requirements for Europe
The Thread Border Router and Gateway
The Linx Thread Border Router and Gateway is a compact, high performance and cost-effective solution to bridge Thread networks to the cloud. It combines an IEEE 802.15.4 radio running the Thread protocol with an Ethernet interface. It manages all of the communications and protocols, so no software development is required.
Unlike competitive solutions, the system runs embedded firmware on an ARM microcontroller instead of costly microprocessors running bloated Linux-based operating systems. As a Border Router, it allows IPv6 direct addressability from the Internet; as a Gateway it allows traditional firewall traversal to device cloud services.
The Thread protocol supports full mesh networking, where every node can communicate with every other node that is within range. Each node can take on one of four roles within the network. The Leader establishes the network, controls communication parameters and commissions new devices onto the network. The End Node sends data to its parent node and does not take part in any routing.
Thread Routers manage sending data across the network. They can also perform other application-specific tasks. The Linx Border Router and Gateway provide means to pass data between the Thread network and cloud-based data services.
Devices within a Thread network can change roles dynamically as the network changes. It is possible for a window sensor to be commissioned onto the network as an End Node. As other devices join the network, it can become a Router to ensure messages from devices further away from the Border Router make it to their destination. It could even become the Leader if necessary.
Linx Raven™ Modules Combine High Performance with Simplicity
The Raven™ module is an IEEE 802.15.4 standard radio paired with an ARM Cortex-M4 microcontroller. The IEEE 802.15.4 standard specifies the radio PHY and MAC layers, the low-level physical control and operation of the radio. This standard has become popular due to its support for low-power and high-reliability systems. It also provides a foundation for standardized wireless communication between products from different manufacturers.
Thread builds on this by defining several software layers that sit on top of the MAC layer. These layers define how information is transmitted and routed through a network. By using the same techniques that are used on the Internet, Thread enables seamless communication from the Internet to the end device.
