Broadband: Improving Frequency Content

Broadband adoption and content consumption

We explore how broadband access drives changes in the quantity and diversity of consumption of online content by using panel data that describes household Internet usage before and after broadband adoption. Our data suggests that on average, broadband adoption increases usage by over 1300 min per month. We also find that information consumption becomes more evenly distributed within the populat...

Frequency Discriminators for Broadband Applications

Frequency discriminators are widely used in electronic warfare systems for the instantaneous frequency measurement of intercepted signals, allowing rapid identification of threat emitters. This paper reviews microwave discriminator architectures based on multiple delay line, phase measurement with parallel digital processing, for operation over decade bandwidths. An alternative reflection mode ...

Nearfield broadband frequency invariant beamforming

This paper presents a method for nearfield frequency invariant broadband array beamforming. This means that we can design an array with associated signal processing to achieve a desired frequency invariant beampattern (as a function of direction) at any nominal finite distance over an arbitrarily wide range of frequencies. The challenge here is to compensate accurately for the nearfield distort...

Broadband Content Distribution - Enabling the "Experience"

One of the many challenges facing a viable Broadband Content Distribution Architecture is that of the content “experience” of the user. Broadband content becomes compelling when it is delivered to the user at the rate and Quality of Service that is required for the specific type of Content. The carrier network(s) connect the content to the users and as such are responsible for delivering this “...
