The module is intended to connect smart antennas to the central communications hub while avoiding EMI.
KDPOF developed the module concept in partnership with ALPS. The LTE-A telematics control module uses Gigabit Ethernet over POF to connect to the central communications hub such as a head unit. Since POF provides inherently high Electromagnetic Compatibility (EMC), the links do not interfere with the smart antenna receivers. Substituting the current RF link with an Ethernet data link will not only aggregate LTE-A packets but other sources such as digital radio as well.
The natural EMC problem-free POF is ideally suited for an Ethernet connection, avoiding back-coupling conditions. In addition, the EMC problem-free link permits simple re-positioning of the antenna module among vehicle configurations. Another advantage is the simple integration with current ISA chipsets thanks to the Ethernet (SGMII/RGMII) host bus of the Gigabit POF transceiver. Furthermore, thanks to the Gigabit capacity of the Ethernet link over POF, the data link will aggregate various data streams such as LTE-A, Wi-Fi, V2x, RDS, DAB radio, etc.
