In the city area the coverage method usually is HFC network, so there must be an effective modulation type to transfer the programs. QPSK is the right choice!! In the HFC network the frequency source is unlimited and the CN value needed must be lower. At the receiving end the CN value needed can be much lower than other modulation type. So no matter how bad the status of the HFC network is, the QPSK can be very useful. 

MMDS is one of the wireless communication methods; its full name is Multichannel Microwave Distribution System. This technology has been widely used in the Radio and TV broadcast area. It is a very effective way to cover the area that is far from the city or the area that HFC can not cover. MMDS system is easy to setup and test, and the components of the system has light weight, and the benefit investment ratio is very high. MMDS system works in the 2.5GHz2.7GHz which is free to everyone.

Furthermore MMDS is an effective method to cover the rural area that is far from the urban, it saves the cost for the cable and optical fiber.

MMDS+ HFC solution is the most effective way to cover the area that you wish. It has a very prosperous future which is even more beautiful than you think. We have finished a lot of success example in the world.
