What is bandwidth and how bandwidth divided?

Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time.

Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps).

Converting Units of Internet Bandwidth

  • Bytes > Bits: Multiply by 8
  • Bits > Bytes: Divide by 8
  • Mega > Kilo: Multiply by 1,000
  • Kilo > Mega: Divide by 1,000
  • Giga > Mega: Multiply by 1,000
  • Mega > Giga: Divide by 1,000
  • Giga >Kilo: Multiply by 1,000,000
  • Kilo > Giga: Divide by 1,000,000

Wired bandwidth standards for connections

  • Dialup Modem 56 kbps
  • T1,E1 (Digital leased landline connection)1.544 Mbps,2.048 Mbps
  • Asynchronous DSL 4 Mbps
  • Ethernet10 Mbps
  • T3 (Digital leased landline connection)44.763 Mbps
  • VDSL 55 Mbps, VDSL 2 100 Mbps
  • Fast Ethernet100 Mbps
  • Optic leased landline connection155 Mbps,622 Mbps
  • Gigabit Ethernet1000 Mbps
  • 10 Gigabit Ethernet 10 Gbps
  • 100 Gigabit Ethernet 100 Gbps

Wireless network standard max download speeds

  • 802.11b11 Mbps, 802.11g 54 Mbps
  • 802.11n 600 Mbps 802.11ac 600 Mbps
  • 3G - HSPA 7.2 Mbps 3G - HSPA+ 21 Mbps,3G - DC-HSPA+ 42 Mbps
  • 4G - LTE 100 Mbps
  • 5G 1 Gpbs (or higher)

The value in Mbps you can divide the former by ~ 1000 (1024 exactly).

Bitrate is 2500Kbps, then 2500/1024 = 2.44Mbps.
