Directional Pattern Design of VHF and UHF Antennas for FM and TV

Speaker: Eric Wandel

Abstract: This lecture discusses pattern development and the effects of the mounting structure on the antenna pattern for both intentional directional antennas as well as non-DA antennas. Techniques for pattern design will be presented, including detailed array theory and NEC modeling. Focus will be given specifically to customizing and optimizing the directional patterns using computer modeling, but outdoor range and anechoic chamber measurements will be discussed. 

Title: spectrum issues for North American broadcasters 

Speaker Charles Rousseau

Abstract: The amount of spectrum that mobile operators are permitted to use by national governments is being rapidly exhausted by growing demand for bandwidth-hungry services. According to Cisco, global mobile traffic will increase nearly eleven fold between 2014 and 2018. Unless more spectrum is made available, mobile services will struggle to cope. This lecture will talk about the political and technical issues about the additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) and related regulatory provisions, to facilitate the development of terrestrial mobile broadband applications, in accordance with Resolution 233 (WRC-12).

Potential interference from IMT devices to C Band satellite broadcast services

Speaker: Guy Bouchard

Abstract: The GSMA recommends that a portion of the C-Band (3.4-4.2GHz) is identified for International Mobile Telecommunications (IMT) at WRC-15. It is one of the few bands where a harmonised portion could be made available for potential future mobile broadband use worldwide and which is large enough to support very high levels of data traffic and the fastest data rates. Some concern has been raised that medium-term mobile broadband deployments in the C-Band in parts of the Asia Pacific could negatively impact the addressable market for C-Band satellite services. This presentation will talk about the effect of this assignment to broadcasters which are heavily relying on C band satellites
