An-Najah National University Mobile Wi-Max Network In cooperation with Jawwal Abed EL-Rahman Sholi Mohammad Baddad Supervisor: Dr.saed Tarapiah 2014

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

Planning Process

Site Planning: Planning Process

Geographical area

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:

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