SUPPLEMENT THE INTERNET OF THINGS IOT CONNECTED DEVICES TO TRIPLE BY 2021 REVEALS REPORT N


ew data from Juniper Research has found that the number of


connected IoT (Internet of Things) devices, sensors and actuators will reach over 46 billion in 2021. This 200% increase, from 2016, will be driven in large part by a reduction in the unit costs of hardware. Juniper forecasts that it will average close to the ‘magic’ $1 throughout the period. The research firms’ latest report,


The Internet of Things: Consumer, Industrial & Public Services 2016- 2021, found that industrial and public services will post the highest growth over the forecast period, averaging over 24% annually. However, the research cautioned that both providers and end-users


will face tremendous challenges when considering IoT deployments at scale. “The platform landscape is


flourishing”, noted research author Steffen Sorrell. “However, analytics and database systems are, for the most part, not architected to handle the Big Data 2.0 era that the IoT brings”. To that end, Juniper identified key areas where disruption is needed, such as spatiotemporal analytics and intelligent systems able to run on less powerful machines (eg routers). Juniper predicted that, without


changes in attitude from some service providers, getting an IoT project off the ground would be too


difficult for non tech-savvy customers. It noted that initiatives such as Exosite’s IoT Alliance (a large partner network) and Rubicon Labs’ flexible business models (pricing according to the value of the data in question) would be fundamental in driving market traction forward. Additionally, the research found


that the security threat landscape is widening. IoT DDoS (distributed denial-of-service) ‘botnet’ attacks have become infamous in 2016, although in the medium-term, personal data theft, corporate data theft and physical asset damage will be the primary goals for IoT hackers. www.juniperresearch.com


IOT DEVELOPMENT KIT WORLD FIRST NB-IOT BASE STATION ACCEPTANCE TESTING AT CMCC


With growing demand for LPWA (Low Power Wide Area) services and applications as part of the Internet of Things (IoT), 3GPP has developed Narrow Band IoT (NB-IoT) as a new cellular air interface that is fully adapted to the requirements of machine type communications. To ensure the significant quality and standardised network deployment, in October, CMCC and Rohde & Schwarz finished the first test session for NB-IoT capable base stations together. China Mobile, a major network provider, has chosen Rohde & Schwarz, a provider of wireless test and


measurement solutions, as a partner to perform the first NB-IoT base station tests according to Release 13 Cat-NB1. CMCC team tested the base station’s RF performance. These include tests cases in area of transmission power, spectrum analysis, group timing and delay, and coverage capability. In a next step, performance tests will include fading scenarios, with one box solution of the fading capabilities of the R&S SMW200A vector signal generator. Rohde & Schwarz is said to be one of the first to offer a base station testing solution for generation and


analysis of NB-IoT signals. The solution consisting of the R&S SMW200A vector signal generator and the R&S FSW signal and spectrum analyser has already been used at leading manufacturers of mobile network infrastructure for base station tests. The NB-IoT signal analysis is performed by the R&S VSE vector signal explorer software option which will be available soon. Users will be able to upgrade to NB-IoT capability to support NB-IoT eco system success. For IoT applications such as smart metering or tracking, low power wide area networks (LPWAN) are needed.


Current technologies rely mainly on 2G and 3G. The new 3GPP standard NB-IoT, which is based on 4G technology, fulfills the general requirements for cellular IoT networks such as wide coverage, improved reception indoors, very low power consumption, low device cost and support of massive numbers of devices. www.rohde-schwarz.com


Digi International has released its ConnectCore for i.MX6UL Development Kit. The kit is a complete, off-the-shelf Single Board Computer (SBC) designed specifically for rapid development, prototyping and productisation of a secure gateway platform for intelligent connected devices. It aims to support more efficient, rapid delivery of connected products and applications requiring multiple access points, offering good reliability and flexibility while facilitating development of key areas – including display capabilities – essential for powering today’s advanced IoT and M2M solutions. The solution offers a complete software


platform requiring little to no hardware development to create a wide range of connected devices, the ConnectCore for i.MX6UL Development Kit is designed around the NXP i.MX6UL System-on-Module (SOM). www.digi.com


CEVA, Inc. together with Himax Imaging,


Inc. and emza Visual Sense, have developed an intelligent always-on visual sensor that handles key power and cost constraints of vision processing for IoT applications. The WiseEye IoT sensor solution features always-on, low power visual sensing. By integrating Himax’ low power CMOS Imager Sensor, CEVA’s low power vision DSP technology and emza’s machine vision algorithms, the result is a solution capable of detecting, tracking and recognising its environment in an extremely efficient manner using a few milliwatts of power. www.ceva-dsp.com


SMART HOME REFERENCE DESIGNS SUPPORT DEVELOPMENT OF IOT DEVICES


Silicon Labs has launched two new wireless occupancy sensor and smart outlet reference designs for the home automation market. These new, turnkey reference designs feature pre-certified wireless technology, open-source hardware design files and industry- standard software stacks along with proven test setups and manufacturing methods. The occupancy sensor reference design


is a compact, pre-certified ZigBee HA 1.2 solution featuring a wirelessly connected passive infrared sensor along with ambient light and temperature/relative

humidity sensors. The occupancy sensor’s small, battery-powered design (the size of two AAA batteries) is very energy efficient allowing it to operate for up to five years before battery replacement. The sensor’s detection range extends up to 12 meters (nearly 40 feet) with a 90 degree viewing window. The smart outlet reference design is a


complete, pre-certified solution for a wirelessly controlled outlet plug that can be used to power and control a wide range of home and building automation products. Powered by an ac main- voltage line, the smart outlet communicates wirelessly to ZigBee mesh networks. www.silabs.com/connectedhome
