mediaxtream
mediaxtream is a network connection via power line or coaxial cable with a data transfer rate of up to 882 Mbit / s. In contrast to the similar carrier frequency systems such as Homeplug , Homeplug AV , DS2 or Panasonic , mediaxtream uses the frequency range from 50 to 300 MHz .
The technology was developed by Gigle Semiconductor , the first IC with the name GGL541 went into mass production in mid-2009 and is a. Installed in Belkin International products .
Properties of mediaxtream
- Transmission medium: 50/60 Hz AC power lines or coaxial cables
- Link data rate: 882 Mbit / s
- TCP data rate: up to approx. 310 Mbit / s
- UDP data rate: up to around 330 Mbit / s
- Area coverage: up to 30 meters (from room to room)
- Transmission method : TDMA .
- Coexistence with home automation : Yes ( X10 , LonWorks , CEBus )
- Coexistence with other carrier frequency transmissions : Yes ( Homeplug , Homeplug AV , DS2 , Panasonic )
- Frequency range PHY : 50-300 MHz
- Modulation methods : OFDM , 1024/256 / 64- QAM , QPSK , BPSK
Summary
Mediaxtream enables the distribution of Ethernet packets via the power lines or coaxial cables of a household's antenna system. The maximum bit rate of 882 Mbit / s enables a net TCP data rate of just over 300 Mbit / s. The transmission has short latency times in the range of one millisecond . Due to the high carrier frequency range, the range for power lines is comparatively short. For this reason, only chipsets are currently being manufactured that enable mediaxtream and homeplug AV communication at the same time . This enables communication with more distant modems and efficient meshing using xtendnet .
