Look at your wireless network like at "project". In this project you will need to find a solution. I think that you can contact your local Huawei office to get contacts of the recommended partner. This partner will help you to design your network. At your place I would ask a partner-company to find a solution.
But get ready to get it much more complicated then you imagine :)
Some of the quastions that you will need to answer are:
How many client will use wireless network in different places at one time.
Maps of the territory (houses schemas) with dimentions.
Areas at the territory where speed must be FAST, slow and so on (in Mbit/s).
Security reqirements.
What type of devices will use it. The bigger count of the different devices - the worser for designing.
Money.
