The Groupe Spécial Mobile Association (GSMA), an association that organises the largest annual event in the mobile industry, has called for more collaboration between Egyptian authorities and the mobile industry for successful introduction of the 4G service in Egypt. Main concerns of GSMA include the scarcity of the spectrum offered to the operators which would hinder rapid and large-scale investments in 4G networks and services. GSMA also called for a clear spectrum roadmap to allow operators to understand how and when sufficient spectrum would be made available. GSMA had previously signed a Memorandum of Understanding (MoU) with the National Telecommunication regulatory Authority (NTRA) to promote a regulatory environment in Egypt that stimulates long-term investment in mobile services.
