# What is the fastest speed for LAN file transfer?

### What is the range of current data transfer rate on LAN

Current data transfer rate on LAN is generally in the range of 100Mbps to 1000Mbps. according to the query of related public information, there are higher data transfer rate on LAN, which depends on the configuration of the network equipment.

### What is the transmission rate of wireless LAN?

Wireless LAN transmission method method are half double full:

802.11b is 11M

802.11g is 54M

802.11n is 150M or 300M

Then the actual transmission of 11M is only 11/8Mb/S=1.38Mb/S or so.

The 54M connection speed is 54/8Mb/S=6.75Mb/S or so.

This has to do with the bandwidth of your router, the speed of your hard disk, and the bandwidth of your network card.

First of all, the hard disk’s general limit of reading and writing speed is about 40M-50MB/s.

The bandwidth of the wired router is generally 100M, which means that the limit speed is 12.5MB/s.

The old NIC is generally 100M, and most of the newer NICs are 1000M (bandwidth is measured in mbps (megabytes per second)), and our general read/write speeds are MB/s (megabytes per second), so the bandwidth divided by 8 is the fastest transfer or read/write speed of this device.

These are in line with the barrel effect, take the lowest one.

And to achieve this speed, you can’t use QQ, which utilizes the Internet. You can use Flying Pigeon Transmission Classic this kind of LAN transmission tool. (Connecting two computers with a network cable is likely to be faster, and the bandwidth and processing speed of the routing is not always enough)

### What is the transmission speed of a Gigabit LAN

Theoretically, the transmission speed of a Gigabit LAN is 125MB/s.

1000Mbps=1,000,000,000 bits/sec=125,000,000 bytes/sec=125MB/s.

The theoretically calculated maximum of 125MB/s for a Gigabit LAN is 125MB/s.

Theoretically calculated maximum of 125MB/s is 125MB/s.

The theoretically calculated maximum of 125MB/s is 125MB/s.

This is the highest speed for a Gigabit LAN. In practice, this means deducing about 12% of the control signal for EthernetHeader, IPHeader, TCPHeader, ATMHeader, etc. In addition, this means that the network loss and line degradation will be eliminated.

Extended Information:

Gigabit LANs utilize all of the technical specifications defined in the original Ethernet standard, including the CSMA/CD protocol, Ethernet framing, full-duplex, flow control, and the management objects defined in the IEEE802.3 standard. Management Objects defined in the IEEE802.3 standard. As a component of Ethernet, Gigabit LANs also support traffic management techniques, which ensure quality of service over Ethernet.

Gigabit LANs provide a seamless migration path that fully protects investments in existing network infrastructure. Gigabit LANs will retain IEEE802.3 and Ethernet frame formats and 802.3 managed object specifications, enabling organizations to upgrade to Gigabit performance while retaining existing cables, operating systems, protocols, desktop applications, and network management strategies and tools.

The speed of data transfer between computers on a LAN is extremely fast, and usually the broadband provided by the communication lines is not less than 10Mbps, and some of them can even reach up to 1,000Mbps.

The slowest time is 9 minutes, and the fastest time is only 6 seconds.

However, you use QQ to transfer data to utilize as if it were the Internet, and the LAN does not have much to do with it. Your internet speed is 4Mbps transferring 5G of data will take about 22 minutes.
