Broadband over power line

(also BPL)

Broadband over power line definition

Broadband over power line (BPL) is a new power line communication method that utilizes electric distribution wiring for high-speed digital data transmission. It takes advantage of a wider frequency range and higher frequencies to achieve quicker data transfer. In fact, broadband over power line relies on preexisting radio spectrum frequencies dedicated to over-the-air communication services, which guarantees uninterrupted transmission.

Broadband over power line types

  • Access BPL. Access broadband over power line technology uses medium-voltage power lines in utility pole cables to enable high-speed data transmission and communication. This type requires three crucial elements: medium-voltage power lines, bypass of a low-voltage transformer, and existing power-distribution system. As a result, access BPLs can offer an alternative to traditional broadband delivery methods like DSL or cable.
  • In-home BPL. This broadband over power line technology uses power lines connected to in-house wiring and sockets as access points. For this method to be functional, there needs to be an Ethernet adapter connected to a power outlet in the room. In-home BPLs enable LAN creation within a building using the existing electrical wiring, eliminating the need for additional Ethernet cabling.

Broadband over power lines benefits

  • Utilizes existing electrical infrastructure.
  • Quicker than traditional broadband.
  • Provides an alternative broadband access method.
  • Lower costs for delivery and maintenance.
  • Simplifies in-home network setup.
  • Offers stability for a Wi-Fi network regardless of placement and distance.
  • Potentially expands broadband availability.
