Internet of Things (IoT)

Long talked about, the technology that allows devices and products to be connected to the internet and therefore more easily to each other is now becoming a reality. It is being called the Internet of Things, and can include any or more of a selection of technologies.


IEEE 802.15.4 is the basis for ZigBee, 6LoWPAN, standard internet protocols, and more, and features in several of mSemicon’s products. Bluetooth too.

Radio Frequency Hardware Technologies

While direct ethernet connectivity is always an option for fixed (i.e. non-mobile) devices, it is rarely practical, which means that connectivity is largely provided wirelessly. The hardware technology to use depends really on the amount of data to transmit, the distance involved, the environment, and on the amount of power available at both ends of the line. Here is a selection of technologies employed by mSemicon:

  • For short-range data transmission (and not necessarily related to the Internet), the ISM (Industrial Scientific Medical) frequency band allows great flexibility for the development of proprietary solutions, when such an arrangement suits. It features in mSemicon‘s portfolio.
  • Mid-range mobile applications: Sometimes, when power is very limited, for example in a mobile application where a battery recharge is either impractical or not feasible for several months at a time, another technology is called for. mSemicon‘s choice is a new ultra low power technology called LORA from Semtech. This very low power technology is suitable for the transmission of limited amounts of data, over several km, and in addition, allows for triangulation, i.e. the detection of physical location. It is also an economical solution.
  • General network connectivity, whether mobile or fixed, when available power is not such an issue, can of course be provided by GSM (or GSP/GPS), another technology in the mSemicon portfolio. This technology, of course, depends on a sufficiently strong local signal at whatever site the product is to be deployed.
