What are the channels of GSM?
There are two main types of GSM channels viz. physical channel and logical channel. Physical channel is specified by specific time slot/carrier frequency.
How many physical channels does GSM have?
Consequently the physical channel is defined as a sequence of radio frequency channels and timeslots. Each carrier frequency supports 8 physical channels mapped onto 8 timeslots within a TDMA frame.
What is a channel structure?
A channel structure is a means of reaching your customer with your products and services. This is essentially a high level view of your sales and distribution channels that outlines the architecture of your business.
What are the types of logical channels in a GSM structure or architecture Mcq?
These are the broadcast channel (BCH), the common control channel (CCCH) and the dedicated control channel (DCCH). Each control channel consists of several logical channels.
What are physical channels?
Physical channels correspond to sets of time-frequency resources used for transmission of particular transport channel data, control information, or indicator information. Each transport channel is mapped to a corresponding physical channel. The PDSCH carries user data and paging information to the terminal.
What is channel assignment What are the types?
The channel assignment problem can be categorised into three different forms, these being Fixed Channel Assignment, Dynamic Channel Assignment and Hybrid Channel Assignment (a combination of fixed and dynamic) [3].
What are the three main parts of a GSM architecture or structure?
The GSM architecture consists of three major interconnected subsystems that interact with themselves and with users through certain network interface. The subsystems are Base Station Subsystem (BSS), Network Switching Subsystem (NSS) and Operational Support Subsystem (OSS).
What is the channel Mcq?
Explanation: Channel acts as a medium to transmit message signal from source transmitter to the destination receiver. Transducer converts a signal from one form of energy to other. Mixer allows mixing of signals while Demodulator helps to extract original message signal from incoming signal.
What is channel mapping in LTE?
LTE technology works based on three channel types viz. logical channel,transport channel and physical channels. They get mapped to physical channels. These physical channels will have different modulation-code rate as mentioned below and are exclusively used by LTE PHYSICAL Layer to carry upper layer information.
