On April 19, 2013, Brazil’s Telecom Regulator Agency - ANATEL approved the application submitted by operators Oi and TIM for the sharing of infrastructure for fourth generation mobile telephony services (4G). Through this decision, ANATEL also approved the temporary sharing of radio frequencies.

The LTE Radio Access Network sharing project between Oi and TIM (LTE RAN Sharing) will have a 15-year validity period and may be renewed. The scope of the project also includes the onerous assignment of the LTE access network and backhaul in 2.5 GHz; the sharing between both companies; deployment of the network in 12 cities in the first year of the agreement, whereas the inclusion of new cities in the scope of the project will depend on the approval of both parties. It is likely that these 12 cities are the cities that will be hosting the 2014 World Cup.

The specialized media reports that two other major carriers, Claro and Vivo, have also applied for 4G infrastructure sharing. According to ANATEL board member Rodrigo Zerbone, each provider can assume responsibility for investments in different locations and share their equipment in service offerings. However, they must maintain distinct investment plans and commercial activities totally separate. Among the identified advantages is the transfer of cost savings obtained by unrealized investments to consumers in the form of the reduction of 4G service prices.
