What are the architectures of 2G & 3G networks?

Let's delve into the architectures of 2G, 3G, and 4G networks, detailing their key components and interfaces. Architecture: Base Transceiver Station (BTS): This is the radio equipment (transceivers and antennas) that communicates directly with mobile handsets. Base Station Controller (BSC): Manages one or more BTS units.

What are 2G 3G & 4G networks?

Let's delve into the architectures of 2G, 3G, and 4G networks, detailing their key components and interfaces. 1. 2G (Second Generation) Architecture: 1. Base Station Subsystem (BSS): * Base Transceiver Station (BTS): This is the radio equipment (transceivers and antennas) that communicates directly with mobile handsets.

What is a 4G base station?

The base station sits at the heart of the network platform. Traditional 4G LTE base stations contain one, two or possibly even four transmitters and usually operate on core band frequencies of up to 2.5 GHz, sometimes even 3.5 GHz and 5 GHz.

How does a base station RF work?

The base station's RF circuitry is housed in a small outdoor module known as a remote radio head (RRH) or remote radio unit (RRU). RRH performs all RF functions such as transmit and receive functionality, filtering and amplification. It also has analog-to-digital or digital to analog and digital upconverters.

Why are base stations important in cellular communication?

Base stations are important in the cellular communication as it facilitate seamless communication between mobile devices and the network communication. The demand for efficient data transmission are increased as we are advancing towards new technologies such as 5G and other data intensive applications.

What is GSM infrastructure?

The GSM infrastructure starts with the Mobile Station (MS), each containing a Subscriber Identity Module aka SIM. Through its RF antenna, it connects to the Base Transceiver Station (BTS). Figure 2 - GSM Infrastructure. The BTS contains the radio transceivers that handles the radio link protocols from the MS.
