Judith Mariscal is a professor at the Centro de Investigación y Docencia Económicas (CIDE) and Executive Director of the Cyber Policy Center for Latin America. She's a leading telecommunications scholar and easily the most knowledgeable and thoughtful person on telecom in Mexico.

For the last few years we've seen lots of big changes, not just in politics in Mexico, but in the telecommunications sector and one of the biggest issues that possibly has broader lessons for the rest of the world is the story of Red Compartida, the wholesale network, where the government provided a 90 MHz block to the 700 MHz spectrum band and awarded build out to a company. It's been hugely controversial. Judith helps explain what's happening.
