This is a sortable list of broadband internet connection speed by country, ranked by Speedtest.net data for March 2024, [1] and with M-Lab data for June 2023 [2] Country/Territory Median
Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest-performance ...
For example, the wire speed of Fast Ethernet is 100 Mbit/s [1] also known as the peak bitrate, connection speed, useful bit rate, information rate, or digital bandwidth capacity. The wire speed is the data transfer rate that a telecommunications standard provides at a reference point between the physical layer and the data link layer. [2]
The development of the 2.5GBASE-T and 5GBASE-T standards enabled wireless access points to reach their maximum speeds without being limited by the Ethernet uplink speeds over a single existing Cat5e cable, while also being compatible with newer Cat6 and Cat6a cabling.
The prior Ethernet speed was 10 Mbit/s. Of the Fast Ethernet physical layers, 100BASE-TX is by far the most common. Fast Ethernet was introduced in 1995 as the IEEE 802.3u standard [1] and remained the fastest version of Ethernet for three years before the introduction of Gigabit Ethernet. [2]
Contention in a wireless or noisy spectrum, where the physical medium is entirely out of the control of those who specify the protocol, requires measures that also use up throughput. Wireless devices, BPL , and modems may produce a higher line rate or gross bit rate , due to error-correcting codes and other physical layer overhead.
The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
50 Ω coaxial cable connects machines together, each machine using a T-connector to connect to its NIC. Requires terminators at each end. For many years during the mid to late 1980, this was the dominant Ethernet standard. Also called Thin Ethernet, Thinnet or Cheapernet. 10 Mbit/s over RG-58 coaxial cabling, bus topology with collision ...
