Iceni. Adaptive digital modulation schemes and error correction methods can be selected according to the trade-off between data rate and range required for a given application. Neul maintains its technology costs less
than $5 in volume from 2012 onwards, going down to a $1 chip set by 2014. It claims a battery life of 15 years for low bandwidth machine to machine (M2M) applications such as smart meters. ●
program, allowing them to chop up a physical structure into numerous small pieces, each of which may need its own supercomputing core.” A parallel development to Big Data is the Internet
of Things (IoT), which can be anything with an IP address, preferably with a RFID tag. RF bandwidth has recently been released in the UK from the switch from analogue to digital TV transmission, known as the license-exempt UHF TV White Space spectrum from 470-790MHz. In February 2013, Neul announced what it claims to be the world’s first TV White Space transceiver chip,

IoT provides the glue for scattered apparatus T
he Internet of Things (IoT) is the name used for a collection of network enabled, often wireless,
devices which communicate with each other via online storage on the cloud. Centrally hosted online cloud storage allows access to data from anything attached to the internet. For example, distillation columns are
controlled by temperature. As the hot hydrocarbons rise, they cool to the point where they liquefy and can be drawn off as one or another petroleum product: gasoline, benzene, kerosene, and so forth. The use of inexpensive wireless temperature sensors in large quantities along the length of a distillation column will provide a very large amount of data to the operators that they have never been able to get before, and that can be used for discovering process bottlenecks

and optimising processes. Such process optimisation is enabled by the IoT according to Advantech. Impulse marketing manager Ben Jervis
claims Advantech selected his company as the first in Europe to promote the IoT According to Jervis, One of the most
important uses of the IoT is hardware monitoring, for example the temperature of a boiler where there would be a thermometer located on the outside of the boiler that would usually be checked at regular intervals by an operative. The IoT automates this process and
wirelessly alerts the operative, remotely if required, of any temperature fluctuations. “The technology for IoT has been around
for at least 10 years, but is fairly recent in terms of how it is uses and reports on data to monitor hardware and predict failures before they happen,” asserts Jervis. “You

are essentially giving an IP address to an inanimate object, eg where a sensor may be attached to a power cable. ●
