This is a list of device bandwidths, or the physical layer information rates also known as net bit rates or useful bit rates, at which digital devices can communicate over various kinds of buses and networks.
Note that especially wireless devices and modems may produce a higher line rate or gross bit rate, due to error-correcting codes and other physical layer overhead. Many of the listed speeds are theoretical maximum throughput measures; in practice, the actual effective throughput may be significantly lower because of Internet service providers rate limiting and bandwidth throttling, network/bus contention due to load from other devices, interframe gap and other overhead in data link layer protocols, etc. The maximum goodput, for example the file transfer rate, may be even lower due higher layer protocol overhead, and due to data packet retransmissions caused by line noise or interference such as crosstalk, or lost packets in congested intermediate network nodes.

[edit] Conventions
By convention, bus and network speeds are denoted either in bit/s (bits per second) or byte/s (bytes per second). In general, parallel interfaces are quoted in byte/s and serial in bit/s. The more commonly used is shown below in bold type.
On devices like modems, bytes may be more than 8 bits long because they may be individually padded out with additional start and stop bits; the figures below will reflect this. Where channels use line codes (such as Ethernet, Serial ATA and PCI Express), quoted speeds are for the decoded signal.
The figures below are simplex speeds, which may conflict with the duplex speeds vendors sometimes use in promotional materials. Where two values are listed, the first value is the downstream rate and the second value is the upstream rate.
All quoted figures are in metric decimal units, where:
- 1 byte = 8 bits
- 1 kbit = 1,000 bits
- 1 Mbit = 1,000,000 bits
- 1 Gbit = 1,000,000,000 bits
- 1 kB = 1,000 bytes
- 1 MB = 1,000,000 bytes
- 1 GB = 1,000,000,000 bytes
- 1 TB = 1,000,000,000,000 bytes
[edit] Bandwidths
The figures below are grouped by network or bus type, then sorted within each group from lowest to highest bandwidth; gray shading indicates a lack of known implementations.

All modems are assumed to be in serial operation with 1 start bit, 8 data bits, no parity, and 1 stop bit (2 stop bits for 110-baud modems). Therefore, a total of 10 bits (11 bits for 110-baud modems) are needed to transmit each 8-bit byte. The "bytes" column reflects the net data transfer rate after the protocol overhead has been removed.

802.11 networks are half-duplex; all stations share the medium. In access point mode, all traffic has to pass through the AP (Access Point). Thus, two stations on the same AP which are communicating with each other must have each and every frame transmitted twice: from the sender to the access point, then from the access point to the receiver. This approximately halves the effective bandwidth.
