What are the protocols used in LTE?
LTE Protocols
- Air Interface Physical Layer.
- GPRS Tunnelling Protocol User Plane (GTP-U)
- GTP-U Transport.
- Medium Access Control (MAC)
- Non-Access-Stratum (NAS) Protocol.
- Packet Data Convergence Protocol (PDCP)
- Radio Link Control (RLC)
- Radio Resource Control (RRC)
What is protocol stack in LTE?
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.
How many layers does a LTE protocol suit have?
A simple way to understand telecom protocol stacks is to divide them in three different layers: the physical layer, the data link layer, and the network layer. These layers are implemented differently in each wireless protocol.
How many layers are in the radio interface protocol?
The radio interface is layered into three protocol layers: – the physical layer (L1); – the data link layer (L2); – the network layer (L3).
What are layers in LTE?
LTE Protocol Stack Layers
- Physical Layer (Layer 1) Physical Layer carries all information from the MAC transport channels over the air interface.
- Medium Access Layer (MAC)
- Radio Link Control (RLC)
- Radio Resource Control (RRC)
- Packet Data Convergence Control (PDCP)
- Non Access Stratum (NAS) Protocols.
Does LTE use TCP?
Abstract. One of the implementation of a wireless network is based on mobile broadband technology Long Term Evolution (LTE). The majority of the Internet connections in the world happen using the TCP (Transmission Control Protocol) due to the TCP’s reliability in transmitting packets in the network.
What are PDU called at each layer?
PDU is a significant term related to the initial four layers of the OSI model. In Layer 1, PDU is a bit, in Layer 2 it is a frame, in Layer 3 it is a packet and in Layer 4 it is a segment. In Layer 5 and above, PDU is referred to as data.
What is radio interface protocol?
The protocol layers above the physical layer are called the data link layer and the network Layer. In the UTRA FDD radio interface, layer 2 is split into sublayers. In the control plane, layer 2 contains two sublayers: the Medium Access Control (MAC) protocol and the Radio Link Control (RLC) protocol.
What is meant by radio interface?
radio interface: The common boundary between a mobile station and the radio equipment in the network, which is the boundary defined by functional characteristics, physical interconnection characteristics, signal characteristics, and other characteristics as appropriate.
What is LTE protocol?
With its architecture based on Internet Protocol (IP), unlike many other cellular internet protocols, LTE is a high-speed connection that supports browsing websites, VoIP , and other IP-based services. LTE can theoretically support downloads at 300 megabits per second or more.
Is UMTS 3G or 4G?
UMTS(Universal Mobile Telecommunication System) is a 3G standard while LTE(Long term Evolution) is a 4g standard. UMTS aims at a peak downlink throughput of 85mbps while for LTE it is around 325 Mbps.
What is LTE architecture?
LTE is a cellular technology. Architecture would mean a collection of things, in this case equipment connected together. So I guess LTE Architecture would mean the connection layout between all the equipment that LTE uses in the core and EUTRAN network. Basically a pictorial layout/connection diagram of various equipment used in LTE.
