Wireless signals are mainly utilized for sensing purposes in different applications like an indoor radar system used for drones & robots or virtual assistants for enhancing performance once many people are speaking within a similar room. The sensing purpose is the reflection & absorption of wireless signals.
Wireless Location Tracking
In wireless communication systems, sensing devices’ locations that are connected to them is the key trend. So, tracking of devices with 1-meter high accuracy within the wireless arena is allowed by a 5G network feature like IEEE 802.11az standard. Location is a key data point required in several business areas such as consumer marketing, supply chains, and IoT applications. Location sensing included with the core wireless network provides many benefits like power consumption, less hardware cost, precision & improved performance as compared to other systems like inertial navigation & fingerprinting.
LPWA (Low-Power Wide-Area) Networks
An LPWAN or low-power wide-area network is a wireless network that allows different devices to converse with each other above long distances with very small power. These networks are applicable where devices need to communicate with each other over long distances, however where power is limited like in the Internet of Things & sensor network applications. The main advantage of these networks is, they can extend the battery life of devices significantly because LPWANs utilize very little power to transmit & receive data so that devices can stay in standby mode for a long time.
Low power wide area networks provide low-bandwidth & power-efficient connectivity for IoT-based applications. Current networks mainly include NB-IoT(Narrowband IoT), LTE-M (Long Term Evolution for Machines), Sigfox, and LoRa which support extremely large areas like cities, countries, etc.
Vehicle-to-Everything or V2X Wireless Systems
The Vehicle-to-Everything wireless systems allow conventional & self-driving cars to converse with each other by the road infrastructure. This wireless system provides a wide range of services in addition to information exchanging & status data like security capabilities, driver information, fuel saving & navigation support.
There are two main V2X technologies in 2019: dedicated short-range communications (DSRC) standard, based on Wi-Fi using the IEEE 802.11p standard, and cellular vehicle-to-everything (C-V2X). This system is mainly designed for improving road security & efficiency by decreasing accidents & traffic jamming. These wireless systems utilize DSRC or dedicated short-range communications for exchanging data like location, direction & speed. After that, the data is utilized for improving safety & traffic flow.
Long-Range Wireless Power
Charging a device on a particular charger point is somewhat better as compared to charging through a cable, although there are various new technologies available to charge different devices at up to the 1-meter range, above a table otherwise a desk surface. So, long-range wireless power could reduce power wires from desktop devices, laptops, kitchen appliances, display monitors, home utility systems like vacuum cleaners, etc.
Wi-Fi is a wireless technology used to allow various devices like computers, mobile devices, printers & video cameras for interfacing through the Internet. It is the radio signal transmitted from a router to a near device that changes the signal into data you can observe and utilize. The device sends back a radio signal to the Wi-Fi router and the router connects to the internet through cable or wire. Internet connectivity mainly occurs throughout a wireless router. Once you access a Wi-Fi network, then you connect it to a wireless router to allow your Wi-Fi-compatible devices for interfacing through the Internet. Wi-Fi is a main choice within high-performance network technology for homes & offices.
5G mobile network is a new global wireless network. It allows a new type of network that is mainly designed for connecting almost everything together like devices, objects & machines. Fifth-generation wireless technology offers higher upload & download speeds, more reliable connections, & better capacity as compared to previous networks.
This is a much more reliable & faster wireless network & it has the potential to change the way we utilize the internet to access different applications, information & social networks. 5G technology increases the amount of transmitted data above wireless systems because of more accessible bandwidth & advanced antenna technology.
Semantic communication is a new paradigm shift within communications. This communication targets what to send instead of how to send it. Particularly, this communication mainly transmits source semantic data depending on the environment knowledge, as a result, the system efficiency is increased significantly & particularly accuracy for difficult artificial intelligence tasks like autonomous driving and virtual & augmented reality which are existing pervasively in future wireless networks.
Additionally, IoT used to connect billions of devices wirelessly can produce huge data that supply “fuel” for AI. Many factors have led to the semantic communication development for future wireless communication networks to permit very quick access to mobile data. But in semantic communications, there are various basic problems still that have not been investigated well for future wireless networks.

This system is very useful in tracking, aiding & monitoring to create communication between trains & control room with the train number & cab number code. Thus, this system will also assist in providing real-time information about the operation of trains during monsoon time.
Steganography is a secret communication method utilized within WSNs wherever the aggregated data is secreted as a message behind a cover picture that appears usually across a not-trusted network. The main purpose of this communication method is to identify suspected data streams, decide whether or not they have secreted messages encoded into them & if appropriate, recover the data hidden. Generally, Steganalysis starts with numerous suspect data streams however uncertain whether any of these comprise a hidden message.
