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
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
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).
The autonegotiating end of the connection is still able to correctly detect the speed of the other end, but cannot correctly detect the duplex mode. For backward compatibility with Ethernet hubs, the standard requires the autonegotiating device to use half duplex in these conditions. Therefore, the autonegotiating end of the connection uses ...
Device interfaces where one bus transfers data via another will be limited to the throughput of the slowest interface, at best. For instance, SATA revision 3.0 ( 6 Gbit/s ) controllers on one PCI Express 2.0 ( 5 Gbit/s ) channel will be limited to the 5 Gbit/s rate and have to employ more channels to get around this problem.
However, Ethernet is designed to be a best-effort network that may experience packet loss when the network or devices are busy. In IP networks, transport reliability under the end-to-end principle is the responsibility of the transport protocols, such as the Transmission Control Protocol (TCP).
DIGI launched the Digi Wi-Fi service in 2011. It is free to use by all DIGI wired internet subscribers, and free for up to 60 minutes per day for guests. There are no paid plans available. Vodafone Romania launched the Vodafone Wi-Fi service in 2012. It allows free connections for up to 60 minutes, after which the user is disconnected.
Because this introduced a new speed option for the same wires, it included a means for connected network adapters to negotiate the best possible shared mode of operation. The autonegotiation protocol included in IEEE 802.3 clause 28 was developed from a patented technology by National Semiconductor known as NWay .
