JupiterMesh® Neighborhood Area Network (NAN) FAQ
Q: What is JupiterMesh?
A: JupiterMesh is a robust, low-power industrial IoT wireless mesh network with flexible data rates that enables neighborhood and field area communications for utilities and municipalities deploying intelligent grid and smart city solutions. Built upon open IETF and IEEE standards, it includes advanced technologies such as IPv6, frequency hopping, multi-band operation, authentication, encryption, and key management to drive industry realization of interoperable multi-vendor implementations that scale and that are secure and easy to manage.
Q: Why is the ZigBee Alliance creating a NAN specification?
A: The ZigBee Alliance represents a global ecosystem of Smart Grid and IoT specialists, including device manufacturers, software and communication network stack vendors and semiconductor vendors. The JupiterMesh stakeholder companies between them have tens of millions of deployed Smart Meters, Smart Grid and Smart City devices deployed on RF mesh communications networks. This expertise and experience has been incorporated in the JupiterMesh specifications.
Q: Why the ZigBee Alliance?
A: The ZigBee Alliance has grown and matured significantly in its 14 years of serving the industry with its initial focus on home automation and lighting. There are well over 100 million ZigBee® Smart Energy 1.x equipped meters and end devices deployed in utilities around the world today. Although JupiterMesh is different from “ZigBee” technology, it has been created within the proven stakeholder consensus standards development process of the ZigBee Alliance. Moreover, the ZigBee Alliance is one of a few industry standards organizations that have a successful history of providing stack specifications, testing and certification programs.
Q: What sets JupiterMesh apart?
A: JupiterMesh has been created by Smart Grid and Industrial IoT specialists in an organization with tremendous experience in certifying products and platforms that deliver rich ecosystems built on multi‐vendor interoperability.
JupiterMesh offers robustness, high data rates (up to 800kbps), best-in-class security for joining and bootstrapping and advanced bandwidth management features such as latency control and guaranteed bandwidth options.
JupiterMesh is a comprehensive solution, which supports a wide range of application standards for smart metering and smart grid including DLMS/COSEM, ANSI C12.19, IEC 61850 and DNP3. New IP-based IOT applications such as Smart City are also supported.
Q: What is the status of the JupiterMesh technical profile specification?
A: The JupiterMesh specification is complete and is now in the process of validation through a series of detailed testing events using several vendor’s implementations. JupiterMesh is also far ahead of other specification in establishing a working interoperability and certification process with globally located test houses which certified over 1,500 product types.
Q: What are the modulation and data rates supported?
A: In addition to FSK and OFDM modulation, JupiterMesh supports O-QPSK modulation to address reaching devices which would be unreachable with other modulation techniques. The JupiterMesh specification supports data rates from 6.25kbps up to 800kbps. During last week’s interoperability testing, multiple vendors successfully tested these different modulation options and data rates.
Q: How does JupiterMesh compare with other Low Power WAN (LPWAN) technologies?
A: Existing LPWAN technologies have limited bandwidth and limited packet sizes which precludes their use for advanced IPv6 based applications. JupiterMesh also offers low-speed high-robustness options.
Q: What does the JupiterMesh specification consist of?
A: JupiterMesh provides a complete solution package, including:
- Technical Profile Specification, detailing requirements from existing open standards for OSI Layers 1 through 4, including:
- IEEE 802.15.4e & IEEE 802.15.4g for Media Access Control (MAC) and Physical Layers (PHY) including multiple modulation options to ensure optimum performance for different use cases;
- IETF network and transport protocols such as; IPv6, 6LoWPAN, UDP, TCP, RPL, CoAP, and others with multicast feature to ensure Internet style machine-to-machine behavior over mesh networks;
- IETF security protocols such as; PANA, EAP-TLS and HIP-DEX for network access authentication and key distribution, and AES-128-CCM-based message authentication and encryption;
- Sub-1 Gigahertz and 2.4 GHz ISM bands as well as multiple modulation techniques (FSK, O-QPSK, OFDM) to ensure global regulatory compliance and acceptance.
- Specification validation, compliance testing, interoperability verification and certification programs, and a global network of test houses.
- Brand identity and commercial collateral for stakeholder promotion.
Q: Which applications does JupiterMesh support?
A: Since JupiterMesh defines Layers 1 through 4 of the Open System Interconnection (OSI) model, it provides a standard IPv6 interface layer capable of transporting existing metering communications protocols, such as IEC TC13’s globally-deployed and highly interoperable DLMS/COSEM, ANSI C12, OpenADR, GOOSE, IEC 61850 and DNP3 as well as evolving solution-specific IP based IoT applications.
Q: Which companies are backing JupiterMesh?
A: The JupiterMesh development work is being delivered by ZigBee Alliance stakeholder member companies including; Analog Devices, ARM, Atmel (a subsidiary of Microchip Technology), Exegin, Itron, Kroger, Landis+Gyr, NXP®, Renesas Electronics, Silicon Labs, Texas Instruments, Trilliant and Vencore Labs (a.k.a., Applied Communication Sciences (ACS)).
