Existence Problem. 


›  Mobile data traffic growth
  
 
› Due to increased usage on Smartphone’s, Smartphone’s will reach 66 percent of mobile data traffic by 2018.
 

 
› In the recent years there has been a skyrocket rise in mobile data usage especially due to the large number of smartphones  in use.


















Capacity and Spectrum


›  Overall capacity is not keeping pace with data demand. 


›  That means future networks supporting the mobile internet will need to integrate smaller cell architectures to scale. 



›  The telecoms operators and providers followed accordingly.


















Possible Solutions


› To solve this problem; dramatic increasing in mobile data traffic; there are several solutions 



› Upgrade the existence infrastructure.

› Offloading to Femto-cells

› Wi-Fi networks. 

› Wi-Max.







Wi-Max VS HSPA








	Feature	Deployment options
	Used spectrum	2.3, 2.5, 3.3, 3.5, etc. GHz
	Bandwidth	1.25 – 20 MHz
	Duplex	TDD or FDD
	Sub channel/frequency reuse	1/3, 1/4 , 1 (PUSC/FUSC)

Spectrum Selection

For this project work, licensed   bands   2.5GHz is therefore   assumed   for   the deployment. channel bandwidth 10 MHz TDD, and spectrum 30MHz. 

	Feature	Deployment options
	Used spectrum	 2.5,GHz
	Bandwidth	10 MHz
	Duplex	TDD 
	Sub channel/frequency reuse	1/3, 1/4 , 1 (PUSC/FUSC)














Cell Radius COST-231Hata Model










Coverage Deployment























Antenna Configuration

 Since mobile Wi-MAX uses shared resources, the data rate per sector is shared equally among all users currently served under the cell.
Due to the low probability that all customers are going to be served in a single base station, it is assumed that at least 10 customers can be served per sector.








Capacity Deployment















Frequency Reuse








Frequency Reuse Scheme:








Where R is the radius of the cell, and N is the number of cells per cluster
