In satellite communications, downlink simply refers to the process when a satellite beams down information toward earthbound terminals or devices. The opposite of this is uplink, where the satellite receives data from an earthbound terminal. In cellular networking, downlink can be seen from the user...
It is also referred to as MU-OFDMA since Wi-Fi 6 supports uplink and downlink MU modes. This technology enables multiple users to reuse channel resources by allocating subcarriers to various users and adding multiple access in the OFDM system. To date, OFDMA has been utilized in 3GPP Long ...

In the early stage of networking, the emergence of the hub brought great convenience to people, and were widely used before the invention of the switch. In a sense, the hub is merely a primitive predecessor to the switch. Therefore, hubs were replaced by switches a long time ago. Meanwhile...
gaming, uplink connections are used to send game data to servers so that multiple players can interact in real-time. in video streaming, uplink connections are used to transmit video data from local devices to streaming servers for distribution to viewers. how is uplink different from downlink...
Very high throughput (VHT) standard:802.11acsupports downlinkmulti-user MIMO(DLMU-MIMO), provides channel bandwidth of up to 160 MHz, and delivers a rate of 6933.33 Mbit/s. High Efficiency (HE) standard:802.11axintroduces technologies such asorthogonal frequency division multiple access(OFDMA), up...
In satellite telecommunication, a downlink is the link from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground station up to a satellite. Some companies sell uplink and downlink services to television stations, businesses and other telecommunic...
When whole-house gigabit fiber FTTR is used instead of traditional wire, the issue of ugly wiring can be simply avoided. Compliant with both dark and bright line networking, the line is more elegant, maintaining the style of design without taking away from it, and it blends in well with th...
When CAT-1 first arrived, in order to meet the standard’s data throughput specification, the cellular modules incorporated into IoT devices needed two antennae for downlink reception. A new standard, CAT-1 BIS, essentially enables CAT-1 devices to operate with a single-antenna design. This mea...
In the opposite direction, which is the “downlink” from data networks to mobile devices, the reverse process takes place: data from services on the Internet or other data networks are processed by the core network and the RAN, and then delivered to mobile devices. Disaggregated RAN Traditional...
