https:// good practice in outdoor wireless networks is to design your base station that has multiple access points, with a frequency re-use pattern.
This is based on data collected from the famous local mobile operator, Zain Telecom Company.
The main contributions of the proposed scheme are to reduce the call blocking and call dropping probabilities.
Operating in today’s outdoor wireless environment can be challenging, especially when using non-licensed frequency bands such as 2.4GHz and 5GHz.
This is where you, the outdoor wireless operator, needs to be conscious of channel spacing as frequency and available spectrum is fast becoming a scarce commodity, especially in densely populated areas.
Such probabilities generally increase with the increase in the number of mobile users.
Thus reduction in call blocking/dropping will enable improved service provisioning in mobile wireless network.The proposed scheme takes into account factors such as limited bandwidth of wireless networks and the capacity of underlying servers involved in processing mobile calls.It aims to ensure end-to-end performance by considering the characteristics of mobile devices.This is achieved by determining the position of users (or mobile stations) in wireless mobile systems.The proposed scheme is simulated in order to investigate its efficiency within a specific area of a large city in Saudi Arabia.The problem of channel assignment becomes increasingly important, i.e., how do we assign calls to available channels so as to improve performance and to minimize interference.This paper proposes a new scheme for channel assignment, which is called (DBFCB) scheme.Mobile phones generally use cellular network system as one of the main communication network.The rate of increase in the popularity of mobile phone usage has far outpaced the availability of usable frequencies which are necessary for the communication between mobile users and the base stations of cellular networks.The channel assignment problem is a complex problem which requires that under certain constraints a minimum number of channels have to be assigned to mobile calls in the wireless mobile system.In this paper, we propose a new scheme, which is based on double band frequency and channel borrowing strategy.
