Uptilted Macros as an Outdoor Solution for Indoor Users in High Rise Buildings

With an expected broadband traffic volume growth of 1000x in the coming years, the need to provide coverage and capacity to the high rise buildings scenarios becomes a challenge for operators. Due to the difficulties in deploying their networks inside buildings, an outdoor alternative is needed. This paper investigates the usage of Long Term Evolution-Advanced (LTE-A) uptilted macros pointing to the upper floors, as an outdoor solution to provide coverage and capacity to high rise buildings. This solution, in combination with the existing downtilted macro and street level micro networks, is able to provide a minimum data rate of 10Mbit/s to 95\% of the traffic beyond 2020.
