1. An apparatus, comprising:
- an antenna adapted to receive RF signals, said antenna having a non-RF data port adapted to conduct non-RF data signals;
a data bus; and
a low frequency coupler coupling said data bus to said non-RF data port of said antenna, and adapted to couple said non-RF data signals between said non-RF data port of said antenna, and said data bus, said low frequency coupler being further adapted to block coupling of RF signals between said antenna and said data bus.

Abstract
Provided are a method, system, and device in which non-RF (radio frequency) data signals are transmitted to a non-RF data port connected to an antenna of a device. The non-RF data signals from the non-RF data port are coupled to a data bus using a low frequency coupler of the device. RF signals are blocked from the data bus using the low frequency coupler of the device. In another aspect, RF signals are transmitted to the antenna of the device and are coupled to an RF port using a high frequency coupler of the device. Non-RF data signals are blocked from the RF port using the high frequency coupler. Additional embodiments are described and claimed.
