Best practices form guidelines for IoT design

Internet of Things (IoT) products using cellular networks now has a design guide released by a cellular group, which also announced a number of operators supporting its embedded SIM standard. Samsung, on the other hand, claimed it is working on a superior implementation of 60GHz Wi-Fi aimed at multiple applications including IoT designs

Neither announcement is expected to shift the balance of on-going work in embedded, networked systems, where cellular and WiFi represent two high-bandwidth options of many communications alternatives.

The GSMA released version 1.0 of its "IoT Device Connection Efficiency Guidelines," a 70-page document outlining best practices for chips, systems and apps riding the cellular network. Backers include mobile service providers AT&T, China Mobile, China Telecom, China Unicom, Deutsche Telekom, Etisalat, KT Corp., Orange, NTT DoCoMo, Tata Teleservices Ltd and Telefnica, as well as module maker Sierra Wireless. The GSMA is a trade group of nearly 800 mobile operators and their vendors.

According to the GSMA's market research division, devices linked to the cellular network could rise from 7.4 billion this year to 10 billion by 2020. If IoT systems fail to use best practices they could disrupt cellular nets. According to the new guidelines:

  • When deployed on a mass scale such devices can cause network signalling traffic to increase exponentially which impacts network services for all users of the mobile network. In the worst cases the mass deployment of such IoT devices can disable a mobile network completely.

The GSMA is developing a set of acceptance tests for IoT devices and applications to ensure best-practices are being followed. It expects the tests to be ready by February.

Separately, the GSMA said five mobile operators and six module makers now have products or services supporting its embedded SIM specification for remote provisioning of machine-to-machine (M2M) devices. Supporters include AT&T, NTT DoCoMo, Telefnica, Vodafone Group, Gemalto, Giesecke & Devrient and Sierra Wireless.

The GSMA's so-called eUICC spec could accelerate growth in M2M by up to 34 per cent, generating about $8.9 billion in connectivity revenues for mobile operators by 2020, according to a new report from Beecham Research. If the standard can unite a currently fragmented market, the number of cellular M2M connections could rise from 478 million today to 639 million in 2020, with cars leading the growth in adoption, Beecham says.

Meanwhile, Samsung announced it will deliver in 2015 products that enable the full 4.6 Gbit/s throughput of the 802.11ad standard for WiFi over 60GHz networks. The Korean giant claims its products will eliminate "co-channel interference, regardless of the number of devices using the same network." It also claims its products will implement both a "wide-coverage beam-forming antenna," and "micro beam-forming control technology."
