"Our collaboration with AT&T will help create the cities of the future in which citizens are safer, healthier and better prepared to handle the challenges of daily life. We must determine how to integrate disparate infrastructure for the common benefit of society," Orvar Hurtig, head of Industry & Society at Ericsson, said on the alliance.

Ericsson will help to establish smart, sustainable cities by connecting the 100 cities in the world with 4G/LTE and enabling intelligent infrastructure connectivity. Ericsson will also invest in safety, transportation and utilities/energy sectors.

The company will also deploy research and sustainability life cycle approach to understand what citizen, business and society value public transportation, inclusion in city planning and smart sustainable city services bring to develop the solutions for tomorrow.

The companies on Wednesday also announced field trials for Connected Water solutions in Atlanta, a city in US state of Georgia, to remotely monitor the quality of the city's water from Chattahoochee river basin.
