Read moreWhat is protocol and protocol stack?
The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family . Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.
Read moreWhat is cellular protocol stack?
The protocol stack functions consist of the Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC) . LTE is the latest generation of the 3GPP standards. The LTE standard specifies an IP-only network supporting data rates up to 150 Mbps.
Read moreWhy protocol stack is required?
The protocol stack is used to allow the combination of different protocols that each set the boundaries for a number of network activities . … These functions are all separated into separate ‘layers’ of data that all require a protocol to be transferred.
Read moreWhat is MAC PDU in LTE?
LTE MAC PDU is a bit string but octet aligned (i.e multiple of 8 bits) . A MAC PDU header consists of one or more subheaders. Each subheader corresponds to either a MAC SDU, MAC control element or padding. MAC PDU header can have these six elements R/R/E/LCID/F/L.
Read moreWhat media access control methods does the 5G cellular use?
A: 5G is based on OFDM (Orthogonal frequency-division multiplexing) , a method of modulating a digital signal across several different channels to reduce interference. 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave.
