  Massive MIMO has been identified as one of the promising disruptive air
interface techniques to address the huge capacity requirement demanded by 5G
wireless communications. For practical deployment of such systems, the control
message need to be broadcast to all users reliably in the cell using broadbeam.
A broadbeam is expected to have the same radiated power in all directions to
cover users in any place in a cell. In this paper, we will show that there is
no perfect broadbeam. Therefore, we develop a method for generating broadbeam
that can allow tiny fluctuations in radiated power. Overall, this can serve as
an ingredient for practical deployment of the massive MIMO systems.
