PSTN/RWS technologies (PSTN / Remote Wireless System) is widely used in various applications such as Mobile phones, Voice over IP, wireless internet, and wireless mesh networks. PSTN/RWS systems are commonly used to provide a reliable, secure, and cost-effective means of delivering voice and data services to remote users. However, they have some unique advantages and disadvantages in comparison to other wireless technologies.In this article, we will discuss the applications and working principles of PSTN/RWS.

Applications of PSTN/RWS

PSTN/RWS is most commonly used in wireless telephone systems. It is also used in many applications such as Mobile phones, Voice over IP (VoIP), mobile networks, wireless internet, and wireless mesh networks. In Mobile phones, PSTN/RWS is used for voice and data services, making it an integral part of cellular phone technology. This technology enables mobile phone users to communicate using voice, text, images, and video. In VoIP, PSTN/RWS is used to provide a cost-effective and reliable means of delivering voice services over the internet. VoIP systems also allow for voice-activated calls, conference calls, video calls, and multimedia applications. PSTN/RWS is also used in wireless internet services such as Wi-Fi hotspots. It is also used in wireless mesh networks, which are used to provide low-cost internet access to remote areas, such as rural villages or emergency zones.

Working Principle of PSTN/RWS

PSTN/RWS systems use an analog or digital circuit switched telephone network to provide wireless services. A PSTN/RWS system consists of a base station, which is connected to the telephone network, and a set of remote wireless stations, which connect to the base station via radio frequency links. The base station is connected to the PSTN/RWS network, and it is responsible for managing the calls between the remote wireless stations and the public telephone network. It acts as a bridge between the wireless and wired systems. When a call is placed from the remote wireless station to the public telephone network, the base station connects the call to the PSTN/RWS network. It then sends a signal to the remote wireless station, informing it that a call is in progress. When the call is completed, the base station sends a signal to the remote wireless station, informing it that the call is complete. The base station also sends a message to the public telephone network informing it that the call is complete and that the remote wireless station is now available for use.PSTN/RWS systems use a variety of technologies to ensure call clarity and security. These include encryption, error correction, and digital signal processing. Additionally, radio frequency is used to transmit data between the remote wireless stations and the base station.

Advantages and Disadvantages of PSTN/RWS

PSTN/RWS systems offer many advantages, including reliability, cost-effectiveness, and security. They do not require line-of-sight for transmission, which makes them well-suited for areas with difficult terrain. PSTN/RWS systems also enable calls to be placed from remote locations without having to rely on wired connections. This makes them ideal for emergency services and video conferencing. PSTN/RWS systems have some disadvantages as well. They are not as fast as other wireless technologies, and they require a base station for connection. Additionally, they are subject to interference from other wireless technologies, which can lead to poor call quality.

Conclusion

PSTN/RWS systems are widely used in a variety of applications, from Mobile phones to Voice over IP and wireless mesh networks. They provide reliable, secure, and cost-effective means of delivering voice and data services to remote users. However, they do have some advantages and disadvantages that should be considered.
