It is undeniable wireless, and sensor powered assets are resonating deeper into daily life, whether in the home as a SMART system or in an industrial environment to innovate, business and home-based infrastructures continue to surge toward IoT built compositions that not only enhance productivity but aid economical action in an ecosphere that is progressively more fast-paced and demanding. Embedded systems provide capability to perform efficient automated tasks that yield value in the IoT business chain. In this climate Embedded Engineers are an increased demand in conjunction with the market value of Embedded Systems. Set to reach 37.5 billion by the end of 2020, the need to know the latest technological developments and how they can deploy value for customer needs is essential for Embedded Engineers in the IoT era.
Part of Wireless LAN technologies, the Wi-Fi Network Protocol operates across the IEE 802.11 Local Area Network (WLAN) Standard. Supporting the 2.4GHz or 5GHz radio frequency band, Wi-Fi expedites short-range communication to multiple devices connected to a single Network. Offering high-speed data transfer via Multiple Input Multiple Output (MIMO) Technology (802.11n) across antennas to receive and transmit data, Wi-Fi Embedded Systems enable multiple streams of data to be combined from various clients. The recent introduction of the Wi-Fi 6 standard, places Wi-Fi innovation at the heart of manufacturing environments wanting to increase efficiency.
Based on the IEEE 802.15.1 Network Standard, Bluetooth delivers short-range and low-power communication that harnesses economical assistance in the operating of multiple devices across a Wireless Personal Area Network (WPAN). Bluetooth deploys frequency at the 2.4 GHz Industrial, Scientific, and Medical (ISM) band to safeguard secure inter-device connectivity amongst a wide spectrum that assists voice and data interaction. Ultimately, producing a Piconet Network connection that facilitates connectivity across a web of slave nodes comprised of the master node input, Bluetooth can operate a variety of use cases to optimise device function.
The Zigbee network is based on the IEE 802.15.4 Personal Network Standard, providing short-range communication between devices at a low bandwidth rate. Constructed of three components- the coordinator node, router, and end device- the Zigbee Network has become widely prominent in the SMART home, powering two-way communication transfer between a sensor and control system. Assets from different manufactures are able to work in sync across one secure mesh network.
Ultra-Wide Band (UWB)
Based on the IEE 802.15.4a Network Standard UWB facilitates low -power, short-range, high-bandwidth Communication Protocol. Operating throughout the GHz frequency spectrum, UWB Technology can co-operate within the established GHz signal. Utilisng pulse radar communication to send data constituted toward spatial awareness that enables a device to track, map, and locate.
Radio Frequency Technology is key in powering multiple forms of communication through a range of frequencies. Facilitating responsive, high-speed rates of data transfer between two circuits. Based on Electromagnetic Radiation (EMR) waves, frequencies can range from 3kHz to 300 GHz. The manipulation of RF is dependable on the use case of the wireless technology in action.
LoRaWAN is a Media Access Control (MAC) Networking Protocol that provides low-power operation across a wide range, connecting devices wirelessly amongst regional, national, and global networks. Sensors transmit and receive use case data through the conversion of radio waves across a Network Server, reaching multiple gateways connected to an IP Network Standard that eventually finds an end node device.
