Nokia and Telef nica Chile have completed the largest indoor deployment of small cells to meet the ever growing 3G and 4G data demands of mobile device users at the Costanera shopping center in Santiago, Chile.

With shopping and food outlets on six floors across 168,000 m2 of retail floorspace and multiple parking levels, the Costanera center in Santiago presents a challenge for operators to provide mobile coverage to thousands of visitors, particularly deep within the building, as the thick reinforced concrete structure can hinder radio signals from the operator's macro network.

Nokia replaced and upgraded the existing distributed antenna system (DAS) with a Flexi Zone small cells network.

Dimitri Diliani, head of Latin America Market at Nokia, said: "This project is a great example of how operators can benefit from using the Nokia Flexi Zone small cell family to meet the demands of mobile device users in a high-traffic indoor environment. The size of our small cells means they are unobtrusive in locations such as this while delivering huge capacity.They manage the demands of the surrounding area in which they are deployed, so in this instance can handle interference from the outdoor macro network ensuring that all subscribers remain on the dedicated indoor small cell network, even when near the edge of the building."

The new Flexi Zone base station network in the Costanera shopping center has increased 4G LTE download speeds by up to 63 times and 3G download speeds by up to seven times, with 4G LTE upload speeds increasing by up to 70 times and 3G upload speeds by up to three times, compared to the performance over the DAS. As a result subscriber usage has increased, with a 100 percent increase in download traffic and 70 percent increase in upload traffic.
