With services being delivered by multiple operators in the same area it remains important to provide quality service. As wireless demands absorb more frequency spectrum it becomes even more important to ensure that those frequencies in the cable plant do not collide. This seminar will produce and analyze data to indicate the potential for issues in the emerging use of common spectrum.

The scope of the seminar includes:

  • Proliferation of LTE signal towers, cell phones and mobile devices leading to increased signal density. Increased usage of licensed and unlicensed bands leading to wider range of wireless signals for general use.
  • Far away (tower) and closer proximity wireless signals stressing the network.
  • Open or low-shielded network entry points such as at the drop, or even within the home, are now becoming increased noise ingress sources.
  • Formal shielding testing at the commonly used CATV spectrum frequencies. Testing to include both loose port junctions and open ports as is common to a home environment.
  • Mathematically deduce what shielding measurements could mean to system noise and performance
  • Propose ideas about how to mitigate noise ingress throughout the network such as loose connections and open ports.
  • Examine new products and techniques that leverage cable installations to be more cost effective throughout the planned evolution of the network. We will demonstrate how a single cable construction investment can 1) allow for a typical RF approach initially, 2) switch to a fiber pathway when needed, and 3) allow repurposing of the copper power applications.
