There's a rise in hefty data practice by indoor users as a result of using their smartphones laptops routers and much more datarelated as they interact with downloaded imagines videos and other multimedia accessories. This heavy rise in data use can be solved by a heterogeneous network when a cellular network is incorporated with Pico cells into the existing Macro cells station. This will not only improve the spectral efficiency of users per unit area but also help operators to upgrade their existing networks to meet up the demands of users. This paper presents a comparison solution considered for the existing layout and the challenges faced by base station layout design are presented.
