Texas Instruments to Sample Smart Meter System on Chip

Oct 12, 2012 (Close-Up Media via COMTEX) -- Texas Instruments announced it is now sampling a fully integrated and optimized Smart Meter System on Chip for smart electrical meter designs.

According to a release, the new Smart Meter SoC combines three independent engines. The metrology engine delivers 0.5 percent meter class accuracy and includes support for one-phase or three-phase meters. The ARM Cortex-M3 core allows ease of development for meter management firmware (DLMS/COSEM, advanced metrology, application profiles, network stack) and security with memory up to 1MB Flash. A communication engine includes support of multiple standards for power line communication and radio frequency communications to allow developers to design products capable of communicating with wide area network and home area network domains and enabled devices.

Features and benefits of TI's Smart Meter SoC: -Certified metrology code is fully independent from the application code, allowing developers to make easy software upgrades and maintenance.

-Communications engine has sufficient memory for field upgrades, which reduces system costs by eliminating the need for external memory.

-Supports TI's plcSUITE software for all narrowband PLC standards including G1, G3, PRIME, IEEE P1901.2, ITU G.9903 and G.9904: a single platform for global markets reduces meter development cost and speeds time to market.

-Includes multiple communication interfaces to easily connect external components like TI's RF transceivers to bridge WAN and HAN on one single chip (sub-1GHz or 2.4GHz).

-Encryption table and memory protection enable developers to include a security implementation on their smart e-meter products.

-Expandable platform to support future smart e-meter features sets because of external memory interface.

-Flexible clock scheme on separate engines allows adaption of processing power and power consumption to application requirements.

-Plugs into TI's new Smart Meter Board 3.0 to support advanced features and near field communication, sub-1GHz, ZigBee and Wi-Fi connectivity options.

-Supports the following TI smart grid software: metrology libraries or metroSUITE compliant with EN 50470-1/3, IEC62053-21/22/23, ANSIC12.1/10/20 for one-phase and three-phase meters; plcSUITE; RF communication in sub-1GHz bands (including 802.15.4g); ZigBee Smart Energy Profile 1.x and SEP2.0 running on the Cortex-M3 core; prepayment MIFARE, NFC and encryption for design ease and flexibility The Smart Meter SoC is available for sampling.

Texas Instruments is a provider of semiconductors.

Oracle in Enterprise Communications

Most in the industry have heard of the acquisition of Acme Packet by Oracle. What you may not know is that Oracle has a number of telecommunications products including a UC suite, WebRTC Session Controller, and Operations monitoring tools. Oracle is pursuing both the enterprise and service provider.

WebRTC Security Concerns

This whitepaper covers two of the most relevant topics in communications industry today: WebRTC and security. We will introduce the problem of security in WebRTC including those traditional VoIP attacks that are going to be present in WebRTC services. Later we will mention ad-hoc WebRTC attacks and protection mechanisms, to close with an overview of identity management solutions.

Migrating Real Time Communications Services to the Web

In the Internet age, businesses that own fixed and mobile communication networks, including traditional Communications Service Providers (CSPs) of all kinds, are being challenged with some tough questions: How do we stay relevant to our customers?

Delivering Enterprise-Class Communications with WebRTC

WebRTC is an emerging industry standard for enabling Web browsers with real-time communications capabilities. It enables enterprises to enhance Web sites, empower BYOD users, and improve video collaboration and on-line meetings, to name but a few examples.

WebRTC Report Extract Reprint

This document examines the growing important of WebRTC, both generally and for telecom service providers. It considers the expanding range of use-cases, the multiple layers of interoperability likely to be desired by telcos, and some implications in terms of network integration and mobility.

Robust Enterprise Grade WebRTC Systems and Services


The emerging WebRTC standard has become one of the industry's hottest topics – and with good reason. Being able to "communications enable the web" has Communications Service Providers as well as Enterprises busily making plans for deployment. But, as these plans unfold, reality is starting to intrude on those plans. Our expectations of telephony services are much higher than web browsing. We expect the phone to connect instantly, operate with minimal disruption, and work seamless across any network, anywhere, at any time. There is also an understanding that phone service is inherently secure. With WebRTC, the expectation is for these applications to behave in the same manner.

This session looks at the user experience and expectations of a WebRTC Enterprise service. It will also cover how a WebRTC enterprise handles security, reliability, and interoperability within browsers and networks.

ORACLE COMMUNICATIONS WEBRTC SESSION CONTROLLER SOLUTION

Communication Service Provider (CSP) voice service revenues continue to face pressure due to shifts in communication preferences and competition from non-traditional service providers. Voice communications are now often embedded into applications outside the domain of traditional telephony voice usage. CSPs have been challenged to effectively leverage and monetize new web-oriented communications technologies.
