Personal Communication System | What is PCS - (BCA / B.Tech)

Personal communication system in Hindi | What is PCS

The Personal Communication System (PCS) architecture is a wireless communication system that provides individuals with the facility to communicate anywhere, at any time, using any device. Its main objective is to provide a comprehensive, convenient, and seamless communication service,
which can include voice, data, video, and other communication mediums. The PCS architecture consists of various components and network elements that together enable this communication system.
The Personal Communication System (PCS) architecture is an important part of modern wireless communication. Its various components and services make it a convenient and flexible option for users.
The main features of a PCS network are its wide reach, mobility, and diverse communication services, which make it a powerful and advanced communication system.

To understand this in detail, we need to look closely at its components and functionality.

Definition of Personal communication system in Hindi | Definition of Personal Communication System:

PCS is a wireless network system that provides users with communication facilities at a personal level. It is used for mobile phones, wireless telephones, internet access, email, and multimedia communication. PCS is designed in such a way that it can provide users with the facility to stay connected with the network always and everywhere.

Components of PCS Architecture in Hindi | Components of PCS Architecture:

The PCS architecture can be mainly divided into three major components:

Terminals

Air Interface

Network Subsystem

1. Terminals:

Terminals are the devices that users use to connect to the PCS network. These can mainly be mobile phones, Personal Digital Assistants (PDAs), laptops, tablets, and other wireless devices. Some of the main functions of these terminals are as follows:

User Interface: Terminals provide users with a means to access PCS services, which includes making calls, sending and receiving data.
Mobility Support: Terminals are designed in such a way that they can remain connected to the network even while moving or changing location.
Service Request: Users can use terminals for various services such as voice calls, data transfer, and multimedia services.

2. Air Interface:

The air interface is the medium through which communication is established between terminals and the base station. It mainly uses the radio frequency spectrum. Various types of multiple access techniques are used in PCS, such as:

FDMA (Frequency Division Multiple Access): In this, the frequency spectrum is divided into different channels.
TDMA (Time Division Multiple Access): In this, each user is allocated a time slot.
CDMA (Code Division Multiple Access): In this, each user is given a unique code, through which data transmission occurs.
SDMA (Space Division Multiple Access): In this, users are allocated channels based on different locations.
The main function of the air interface is to ensure that data transmission between terminals and the base station can happen seamlessly, no matter where the user is.

3. Network Subsystem:

This is the main component of the PCS architecture, which establishes communication between terminals and the external network. The network subsystem includes various components:

Base Station Subsystem (BSS):

This is the most important part of the PCS architecture, which establishes the connection between terminals and the network.
It mainly consists of two components: the Base Transceiver Station (BTS) and the Base Station Controller (BSC).
The BTS is the antenna that receives signals from the terminals, and the BSC controls it. The BSC performs handoffs between different base stations and other important operations.

Mobility Management:

The main task of this component is to track the location of users and ensure the availability of services to them.
It manages services like location updates, call setup, and call handoff.
Mobility management includes the Home Location Register (HLR) and Visitor Location Register (VLR), which store user information and track their location.

Switching Subsystem:

This component is responsible for establishing communication between different networks. It includes the Mobile Switching Center (MSC), which connects the PCS network to the PSTN (Public Switched Telephone Network) and other mobile networks.
The MSC is responsible for routing calls, controlling the handoff process, and conducting various security procedures.

Operations and Maintenance:

This subsystem is responsible for the operation and maintenance of the PCS network.
It handles tasks related to network monitoring, fault management, and performance management.
Under this system, the network is monitored so that any kind of problem can be solved immediately.

Services in PCS Network in Hindi | Services in PCS Network:

PCS network offers various types of services, which distinguish it from other traditional communication systems. These include:

Voice Services: The PCS network provides users with the facility to make and receive voice calls anywhere and at any time.
Data Services: Through the PCS network, users can access the internet, send and receive emails, and avail other data services.
Multimedia Services: PCS also supports video calls, video streaming, and other multimedia services for users, making the communication experience richer and more useful.
Location-Based Services: The PCS network can track the location of users and provide them with related services, such as navigation, location tracking, and emergency services.

Advantages of PCS Architecture in Hindi | Advantages of PCS Architecture:

Communication anywhere and anytime: The PCS network provides users with the facility to communicate from anywhere, at any time, and from any device.
Diverse services: The PCS network offers voice, data, video, and multimedia services, giving users a richer communication experience.
Seamless connectivity during handoff: In the PCS architecture, users get seamless connectivity even when moving from one cell to another, so communication is not interrupted.
Mobility: The PCS network supports mobility, meaning users can stay connected to the network wherever they go.
