difference between uplink and downlink ports

#DIFFERENCE BETWEEN UPLINK AND DOWNLINK PORTS PC#

Reference signals are also known as pilot signals or pilot carriers. Helps in channel estimation and equalization. Dedicated reference signals are assigned for all the antenna ports individually, which.Each antenna port represents specific and unique channel model.It is the logical concept and not the physical one like RF antenna.The term 'antenna port' is related to physical layer.Increase data rate (using spatial multiplexing). These multiple antenna ports are used to achieve greater data reliability (using transmit diversity) or to They are used to transmit data from eNB/gNB to the UEs. Introduction: The downlink frame from Base station to UEs in LTE and upcoming 5G NR ('New Radio') technologies areĬonfigured to use multiple antenna ports. This page compares Antenna ports vs Physical antennas and mentions difference between Antenna ports and Physical antennas concepts

Therefore, there are no big differences between them. In fact, uplink port can serve as normal port. Nowadays, many network equipment offer a dual-purpose port which can function either as an uplink or a normal port depending on the type of device connected to it. Connecting devices to both ports of a shared port device stops the unit from functioning properly. Specifically, the hardware logic of these products supported connections to either the uplink port, or the normal shared port, but not both. Some older network equipment specially configured a normal port next to the uplink port and linked the two together as a pair. Normal Port: Additional Information about Shared Port and Dual-purposed Port Here is a figure for you to have a better understanding of this. If a crossover cable is used to connect them, then the ports at both ends must be the same kind of port. Therefore, when two network switches are connected together with a straight-through cable, then one end must be uplink port and one end must be normal port. An uplink port does not crossover the transmit and receive pins, but a regular port does. To achieve the link connection, the transmit pins at one end of network cable have to be connected to the receive pins at the other end. Normal Port: Connect to Different CablesĮach Ethernet interface has two transmit pins and two receive pins. In most cases, uplink ports have more bandwidth as compared to normal ports as they aggregate traffic between different layers.

While normal port on switch is used to connect end user PC or server and all. This type of port simplify connects different types of Ethernet devices to each other, such as when linking a local home network to a modem and the Internet. And it may be labeled WAN or Internet instead of uplink. Also in computer network, hub, unmanaged switch and router typically designate one Ethernet port as the uplink port. For example, edge switch connects “up” to distribution layer managed switch. The uplink port on switch is used to connect a device or smaller local network to a larger network, or connect to the next “higher” device in the topology. Normal Port: Connect to Different Devices How much do you know about them? Is there any difference between them? This article will guide you to learn about uplink port vs. If you have used managed switch in your network deployment, you must have heard about uplink port or normal port. When it comes to network switch, we usually ask about the port type on the switch and the number of port, such as twenty-four 10/100/1000 Mbps ports and four SFP+ ports.
