Periodic Reporting for period 1 - SMARTRange (A disruptive wireless transceiver chip to transform the Internet of Things (IoT) by delivering excellent range, ultra-low power, high security, high reliability and cost-effective connectivity.)
Reporting period: 2019-10-01 to 2020-10-31
However, existing IoT technology is failing to meet these needs. Current 2.4GHz radios have limited range and sub-GHz radios do not give security or global interoperability. There are two ways to increase the range of radio devices: 1) increase transmit power or 2) improve the radio’s receive sensitivity. However, legislation in Europe limits transmit power to 10mW, meaning the only practical way to increase range is to improve sensitivity.
Cascoda has developed a disruptive 2.4GHz wireless transceiver based on a patent-protected radio architecture, which improves receive sensitivity, effectively doubling the range without using any external power amplifiers. This delivers the range of WiFi to provide whole-house coverage, reduces power consumption by a factor of 6 enabling years of operation from batteries, provides high security, reliability and reduces equipment costs by a factor 5. Extensive R&D and market feasibility studies including a Eureka Eurostars and a H2020 Phase 1 project, have taken us this far. This Phase 2 project will allow us to optimise, refine and certify our products under industry standards and demonstrate our systems under real-world conditions. This project enables us to enter a market worth >€3B.
An evaluation kit for the Chili2 module incorporating Cascoda’s existing device, the CA-8211, was created (WP2). The software for the module was developed, exhaustively tested and has been integrated into Cascoda’s Software Development Kit (SDK). The module has been FCC/IC/EU as well as Thread certified.
The ZigBee PRO Network layer and Application layer compatible with the ZigBee 3.0 standard has been developed and tested (WP3). Specific tests are still running, but the system is essentially ready for ZigBee certification.
The OCF Application Layer (WP4) has been adapted and developed to run over the Thread network layer. It has been comprehensively tested and is ready for OCF certification.
The development (WP5) of a new device for Smart Buildings & Smart Industrial Applications, the CA-8212, is nearing completion of it’s design phase. This device incorporates features of the IEEE 802.15.4 2015 and Thread 1.2 specifications as well as additional power saving features. For this a DC-DC converter has been designed and is integrated in the device. The digital hardware of the device has been extended to incorporate all above features. Existing blocks of the design were re-simulated and modified where necessary in order to extend the temperature range of the device. Development of the firmware for the new device are still ongoing and is being continuously tested together with the hardware in system simulations.
* Thread for the IP-based mesh network-layer
* Open Connectivity Foundation (OCF) for the application-layer
The combination is called OCF-over-Thread, and Cascoda is the only company in the world to have achieved this milestone. OCF-over-Thread allows for device-device and device-cloud connectivity, with Public Key Infrastructure (PKI) security for secure end-to-end connectivity. This level of security is required by the forthcoming baseline IoT security standards from the US, EU and UK. OCF has been benchmarked against these security standards and has been formally accepted as compliant. No other solution in the world supports such baseline standards.
Standards are important because adoption of IoT technology in building automation systems (BAS) demands such standards. The social economic impact are significant, since according to a recent report by Carbon Intelligence, buildings in Central London still used over 80% of their nominal energy consumption, despite being completely empty during the corona virus lock down in April and May 2020. Cascoda's technology can provide automation of such systems, and therefore significantly reduce carbon emissions, environmental pollution and work conditions.
