− | This is a '''list of device bandwidths''', or the maximum speeds at which digital devices can communicate over various kinds of [[computer bus|buses]] and [[computer network|networks]].
| + | [[Category:Network]][[Category:Computer]] |
− | | |
− | Many of the listed speeds are theoretical maxima; in practice, the [[measuring network throughput|actual effective throughput]] may be significantly lower because of [[contention (telecommunications)|network]]/[[bus contention]], line noise or inefficiencies in [[network protocol]]s, [[line encoding]]s or arbitration schemes.
| |
− | | |
− | == 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 communications|parallel]] interfaces are quoted in byte/s and [[serial communications|serial]] in [[bit/s]]. The more commonly used is shown below in '''bold''' type.
| |
− | | |
− | On devices like [[modem]]s, 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 code]]s (such as [[Ethernet]], [[Serial ATA]] and [[PCI Express]]), quoted speeds are for the decoded signal.
| |
− | | |
− | The figures below are [[simplex communication|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 [[binary prefixes#Suggestions for new prefixes|decimal units]], where:
| |
− | * 1 byte = 8 bits
| |
− | * 1 kbit = 1,000 bits
| |
− | * 1 kB = 1,024 bytes
| |
− | * 1 MB = 1,024 * 1,024 bytes
| |
− | * 1 GB = 1,024 * 1,024 * 1,024 bytes
| |
− | * 1 TB = 1,024 * 1,024 * 1,024 * 1024 bytes
| |
− | | |
− | == 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.

A [[basic rate interface]] (BRI) provides 2 "B" channels and one "D" channel. Each B channel provides 64 kbit/s bandwidth and the 'D' channel carries signalling (call setup) information. B channels can be bonded to provide a 128 kbit/s data rate. Primary rate interfaces (PRI) vary depending on whether the region uses E1 (Europe, world) or T1 (North America) bearers. In E1 regions, the PRI carries 30 B-channels and 1 D-channel; in T1 regions the PRI carries 23 B-channels and 1 D-channel.

− | [[802.11]] networks are half-duplex; all stations share the medium. In access point mode, all traffic has to pass through the AP ([[Wireless access point|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.
