M2M Comunications ensuring that each machine functions autonomously. Local queries should not be interrupted by a background data exchange, which is important for maintaining responsive interaction. Machines in an ecosystem often run on a variety of platforms and processor architectures, so the database should be capable to keep them connected with a cross-platform approach to data management – even with a custom file system and no operating system. M2M manufacturers need to ensure that these machines are communicating with each other while executing queries and meeting other data management expectations. This requires a solution that connects databases across systems, handling data exchange and high availability for the machine, while providing continuously maintained redundant copies so that data is always available and machines can always wake up and communicate. Such requirement necessitates a cross-platform technology in which any combination of hardware and operating system software can be used to create redundancy. Another important requirement is the ease of configuration for a variety of M2M scenarios, whether data flows bidirectionally or only in one direction. Dynamic configuration settings should be stored directly in each database file, and be applied without any restart or reload step, and should allow changes to the local database to be automatically tracked and exchanged with peers whenever a connection is available. ITTIA DB SQL’s M2M solution is a software library for storing data that should be later transmitted to other machines. This ensures manufacturers a proper M2M communication, while queries and other data management expectations are also met. Using M2M data analysis, each machine can run various SQL queries to make decisions on data after it is transported and saved. Also, change notifications allow a machine to set up an event queue to monitor for changes in specific tables, especially via machine-to-machine protocols. Key features of ITTIA DB SQL’s M2M solution are its interoperability and maintainability, its single-user and multi-user options to simplify data management without the complexity of a back-end database server, multi-threaded concurrency. The database solution also allows shared access to automatically perform the necessary locking when a database is shared between devices. Built-in replication duplicates changes across multiple databases, even if connectivity is not always available, then row-level locking allows the database to interact with other systems and share data without interrupting normal usage. ITTIA DB SQL equips machines with big data capabilities for smart embedded systems with limited local resources. With this unique technology, a large data set can be distributed across a wide array of devices, with the potential to store millions of rows per device. Machines can then run queries on individual machines, or pool data together in a back-end system for data warehousing and data mining. Manufacturers benefit from highly reliable embedded database software with a strong track record in mission-critical systems, which allows smart systems to manage, connect, and analyze data obtained from machines or humans (M2M or H2M) – adding value to machines with “intelligence” in the M2M framework that are able to scale and have an adequate memory capacity to store and communicate data, no matter how small these machines are. Lime Microsystems partners with Europractice to bring flexible RF to universities across EU Lime Micro has just announced a deal with Europraxis that will see its open source Myriad RF platform and its field programmable transceiver put in front of all EU universities. The company is hoping this will vastly increase both RF skills in graduates and the number of people innovating wireless systems. Under the terms of the deal, Europractice will promote Lime’s LMS6002D field programmable RF transceiver and associated boards for use in research and teaching of wireless technology to its member establishments throughout Europe. This will begin immediately. The list of boards includes both Lime’s Universal Wireless Communications Toolkit and Azio’s Myriad RF-1, an open source board created for Lime’s non-profit MyriadRF initiative, which seeks to increase access to RF hardware -through low cost, easy to use boards - and advance wireless system innovation. The products enable the creation of highly flexible wireless systems. The field programmable RF (FPRF) transceivers are software configurable for all major wireless communication frequency bands (300 MHz to 3.8GHz) and standards (including LTE, HSPA+, CDMA and 2G). FPRF ICs are highly user-programmable. In this way, they bear comparison with FPGAs, which can be used for implementing complex digital logic functions. In contrast, the FPRF comes from the wireless domain, and brings exciting new possibilities. By combining the FPRF with an FPGA, users have an even greater range of possibilities. The Myriad-RF board can be easily connected to Altera and Xilinx boards. And Lime’s Universal Wireless Toolkit gives connectivity to Altera evaluation boards.
