Wireless networks with a large DBP can have a throughput larger than the one based on traditional understanding. We propose a scheduling algorithm aims for making use of the large DBP in wireless networks. We then design simulations to figure out how much throughput gains can be achieved in wireless networks, with small DBPs and large DBPs respectively.

Therefore housing investment is an important factor for short-term economy fluctuations and lead to downside risk in the long term. The effect of real estate investment also rely on the regional economy development and has periodic characteristics, which is stronger in the eastern region than the midwest region and the negative enduring impact is strengthened after 2004.
