Pertaining to radiocommunication service, an uplink (UL or U/L) is the portion of a feeder link used for the transmission of signals from an earth station to a space radio station, space radio system or high altitude platform station.

The uplink frequency is the frequency which is used for transmission of signals from earth station transmitter to the satellite. The downlink frequency is the frequency which is used for transmission of signals from the satellite to the earth station receiver.

The communication going from a satellite to ground is called downlink, and when it is going from ground to a satellite it is called uplink. When an uplink is being received by the spacecraft at the same time a downlink is being received by Earth, the communication is called two-way.

1 : a communications channel for transmissions to a spacecraft or satellite also : the transmissions themselves. 2 : a facility on earth for transmitting to a spacecraft or satellite.

In satellite communication, uplink means that data are being passed from any earthbound terminal or device up towards the satellite. For example when sending a text message, the phone creates an uplink with the base station in order to send the text message. The inverse is receiving a text message through a downlink.

The uplink port is used to connect a device to other higher-speed ones in the topology or smaller local network to a larger network. For example, the edge switch connects “up” to the distribution layer managed switch.

When to Use an Uplink Connection

1. Connect a broadband modem to a home router for internet access.
2. Connect one uplink device (a router, switch, or hub) to another. Plug the uplink port of one switch, for example, into the standard port of another switch to expand the network size.

An uplink is a template that you use to configure physical connections of hosts as well as failover and load balancing policies. You set failover and load balancing policies over uplinks and the policies are automatically propagated to the host proxy switches, or the data plane.

Conclusion. In fact, uplink port can serve as normal port. Therefore, there are no big differences between them. The only difference is that uplink port is connected to higher layer network device to aggregate the bandwidth and must be connected to the normal port on another network device.

It does not make any difference what port you use to connect to the internet. Your smart devices will connect to the internet through the switch. Your smart devices will connect to the internet through the switch. All smart devices would need an ethernet connection.

11 Replies. An uplink port would be used to pass traffic to another switch or router or network device. A trunk port would be used to pass VLAN traffic between two switches or other network devices.

There’s no difference in the ports. The link LED lights a particular color to indicate when there is a link to equipment at the other end of the cable and the speed of the link, while the ACTive LED blinks to show when there is traffic activity on the port.

An uplink port is a port on a router or switch designed to connect to another router or switch or an Internet access device. Most home routers include an uplink port for connecting a cable or DSL modem. An uplink port looks like a standard Ethernet port, which is a female jack for an RJ45 connector.

What Is Uplink SFP Port? An uplink port is a port on which transmit and receive are reversed, which is designed for inner-switch connection with a standard straight-through cable instead of crossover cable. Thus, the uplink port can connect to a regular port of another device.

An uplink port generally means a port used that connects toward the core of the network. A downlink port generally mean the converse. In this particular usage, the switch’s downlink ports are dual speed copper ports. The uplink ports are gig and copper/fiber capable.

Starting an Uplink or Downlink Test

1. Press the Mode button.
2. Press BS Emulator and press Test Mode to select DL Ping Test, UL Padding Test, DL UDP Test or HARQ Test.

In the next generation HetNets, instead of being connected to a specific cell, a mobile user can independently receive the downlink traffic from one base station (BS) and transmit uplink traffic through another BS. …

Uplink speed is the speed at which data can be transferred from the router to your ISP. This is determined by your ISP. ISPs often specify speed as a downlink/uplink pair; for example, 1.5Mbps/284kbps. Alternatively you can test your uplink speed with a service such as www.dslreports.com.

why is uplink slower than downlink uplink rate is higher than downlink rate…. this is due to the power availability since satellite get power from sun and higher frequency needs more power….

Try to download a test file within the serverius network. For instance: http://speedtest.serverius.net/files/2000mb.bin If this gives a good result, you will know its not your server or switch or uplink. Does the external network provide enough bandwidth?
