Abstract: Methods and apparatus for multi-purpose metering are disclosed. An example method includes acquiring a rate of data transfer to/from the monitored location and comparing the acquired rate of data transfer to a threshold. The example method also includes setting at least one media monitoring device in a first bandwidth mode when the acquired rate of data transfer exceeds the threshold, and setting the at least one media monitoring device in a second bandwidth mode when the acquired rate of data transfer is below the threshold.

Abstract: Balanced microstrip folded dipole antennas and matching networks are disclosed. In some examples, an antenna system includes a folded dipole having first and second portions, a first transmission line located on a first side of a printed circuit board, a second transmission line located on a second side of the printed circuit board opposite the first transmission line, the first and second transmission lines being coupled to respective folded dipole portions, and a balanced microstrip matching network comprising first and second portions, the first and second matching network portions coupled to respective ones of the first and second transmission lines.

Abstract: Balanced microstrip folded dipole antennas and matching networks are disclosed. In some examples, an antenna system includes a printed circuit board having first and second dielectric layers, and respective portions of the first and second dielectric layers bound a ground plane. The system further includes a balanced folded dipole, wherein a first portion of the folded dipole is located on the first dielectric layer, and a second portion is located on the second dielectric layer. First and second transmission lines are coupled to respective folded dipole portions. A matching network includes first and second portions that are coupled to respective transmission lines and have equal impedances. Each matching network portion includes a tapered first microstrip, having a narrow end coupled to a respective transmission line, a second microstrip coupled to the first microstrip, and a third microstrip coupled orthogonally to the second microstrip via a mitered bend.
