The architecture of 2G/3G/4G networks involves multiple layers and components for communication and data transfer.
2G architecture includes Base Station Subsystem (BSS), Mobile Switching Center (MSC), and Home Location Register (HLR).
3G architecture includes Node B, Radio Network Controller (RNC), and Serving GPRS Support Node (SGSN).
4G architecture includes Evolved Node B (eNodeB), Mobility Management Entity (MME), and...
Call flow in GSM refers to the sequence of events that occur during a phone call in a GSM network.
The call is initiated by the caller and a request is sent to the nearest base station.
The base station sends the request to the Mobile Switching Center (MSC) which then routes the call to the recipient's network.
The recipient's network sends a signal to their phone to alert them of the incoming call.
If the recipient answer...
VoLTE stands for Voice over LTE, which enables voice calls over a 4G LTE network. ViLTE stands for Video over LTE, which enables video calls over a 4G LTE network.
VoLTE enables voice calls over a 4G LTE network
ViLTE enables video calls over a 4G LTE network
VoLTE and ViLTE both utilize the 4G LTE network for communication
VoLTE and ViLTE provide higher quality and faster call setup compared to traditional voice and video...
Each generation of mobile networks has different spectrum and data rates.
2G networks operate in the 900 MHz and 1800 MHz frequency bands with data rates up to 384 kbps.
3G networks use a variety of frequency bands, including 850 MHz, 900 MHz, 1900 MHz, and 2100 MHz, with data rates up to 2 Mbps.
4G networks operate in the 700 MHz, 800 MHz, 1800 MHz, 2100 MHz, 2300 MHz, 2500 MHz, and 2600 MHz frequency bands with data rat
Routers and switches are network devices that operate at different layers of the OSI model. They have different functions and use different protocols and configuration commands.
Routers operate at the network layer (Layer 3) and are responsible for forwarding data packets between networks.
Switches operate at the data link layer (Layer 2) and are responsible for forwarding data frames within a network.
Routers use routing...

SS7 protocols are signaling protocols used in telecommunication networks for exchanging information between network elements.
SS7 protocols are used for call setup, routing, and tear down in traditional circuit-switched networks.
They are also used for services such as caller ID and call forwarding.
Examples of SS7 protocols include ISUP (ISDN User Part) and SCCP (Signaling Connection Control Part).
Modulation techniques are methods used to encode information onto a carrier signal for transmission.
Modulation techniques are used in various communication systems.
Some common modulation techniques include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).
AM modulates the amplitude of the carrier signal to encode information.
FM modulates the frequency of the carrier signal to encode inform...
SIP call flow is the sequence of steps involved in establishing, maintaining, and terminating a Session Initiation Protocol (SIP) call.
SIP call flow involves several steps such as registration, session establishment, media negotiation, and call termination.
The call flow typically starts with a SIP client sending a REGISTER request to a SIP server to register its address.
To initiate a call, the caller sends an INVITE re...
