EIB Twisted Pair (TP) uses base-band transmission. Its bit-level collision detection (with dominant logical 0) ensures that in case of collision, the transmission always succeeds for one of the communication partners.

The resulting elimination of re-transmissions further enhances the performance of EIB TP. Together with EIB's powerful group addressing, EIB TP1 Collision Avoidance caters for extreme efficiency with reaction times 100 ms for two simultaneous transmissions. Fast polling allows up to 14 devices to be polled for 1 byte status-information within 50 ms. A physical TP segment may be up to 1 000 m long.

Powerline

EIB Powerline (PL) uses a novel Spread Frequency Shift Keying modulation technique. With a corresponding numerical matched filter, the available BAU's guarantee adequate communication for group addressing to work reliably on PL. Medium access is controlled via a preamble sequence, with randomised re-transmission slots.

Maximum distance between 2 devices (without repeater): 600 m. (Communication is influenced by electromagnetic pollution conditions local to the installation.)

EIB Radio-Frequency + Infrared

These new media are currently being defined.

EIB Advanced Network media

As explained elsewhere on this Website, the EIB Advanced Network specifies EIB integration on any IP (Internet Protocol) medium, including 10 or 100 Mbit Ethernet, or 10 Mbit Wireless Lan.
