One of the most important issues in the design of a cellular radio network is to determine a spectrum-efficient and conflict-free allocation of channels among the cells while satisfying both the traffic demand and the electromagnetic compatibility (EMC) constraints [].

In general, if distance is required in your outdoor wireless link, opt for smaller channel width like 20MHz and 10MHz.

If your distance is not too great and throughput is required, you can opt for the larger channel width such as 40MHz and 80MHz.

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.

This constitutes an important bottleneck in the provided capacity of mobile cellular systems.

Careful design of a network is necessary to ensure efficient use of limited frequency resources.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 the beam-width of the access point antenna, for example – with a 90 degree sector antenna, an ABAB configuration is possible.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 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.The objective of the proposed scheme is to optimize channel utilization, improve performance and to reduce the blocking probability of calls in a wireless mobile network system.The proposed scheme is systematically developed and validated through various simulation experiments.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.
