Wireless broadband subscribers have tripled in the past two decades in the world. It subsequently adds more burden on the network traffic, thereby pressuring the current 2G / 3G wireless network infrastructural development in Freetown, Sierra Leone. The existing 2G / 3G network infrastructures in Freetown offer limited resources for download and upload speed of 12.54Mbps and 2.59Mbps, respectively, to active subscribers. The exponential increase in the country’s population has adverse effects on the subscriber’s database. Therefore, a considerable task is faced by the country’s telecommunication network infrastructures to devise an improvement and efficient technologies to augment the current system to handle the numerous issues. Three active private mobile network operators (X, Y, & Z) and one Government-owned operator (W) exist in the country. The only operator that runs across the country is operator X, and it has the highest number of subscribers. The country has just rollout it Long Term Evolution (LTE) by the private MNOs.
The research is to encourage the Sierra Leone National Telecommunication Commission (NATCOM), a telecommunication regulatory body, to mandate all MNOs in the country to roll out the 4G LTE core network infrastructure in Freetown. ARIMA model is used to analyze the throughputs (kbps) prediction to ascertain 4G LTE rollout using the Python programming language is an effective alternative. Statistical data from operator X for ten years for Freetown municipality from January 2010 - November 2019 was collected. The research concludes that 4G LTE deployment or upgrade was necessary for the Freetown municipality.

A 4G LTE Evolved packet Core Planning and Deployment in Freetown Sierra Leone

Real-time, individualized traffic-routing assignments and recommendations are automatically determined and provided to multiple participants traversing through a specific area in association with a given event associated with a particular organization. A set of rules is applied to minimize the time to traverse through the area in association with the event, summed over the multiple participants, accounting for physical and incentive-compatibility constraints. An initial assignment is determined for each participant, based on the rules. Each initial assignment includes a departure time and an initial route for the participant. Updated information is received, such as real-time traffic information. Real-time recommendations are determined for participants, based on the rules accounting for the updated real-time data. Recommendations include suggestions to deviate from initial assignments or previous recommendations, based on the updated information. The initial assignments and real-time recommendations are provided to the corresponding participants, for example by communicating with their mobile devices.

A device receives network data associated with a network that includes network devices interconnected by links at an Internet protocol (IP) layer and an optical layer of the network. The device receives constraints associated with determining a network plan for the network, and determines multiple potential network plans for the network based on the constraints and the network data. The device generates a multilayer and interactive user interface associated with the multiple potential network plans, and provides the multilayer and interactive user interface to a client device. The device receives, from the client device, information indicating an interaction with the multilayer and interactive user interface, and modifies the multilayer and interactive user interface, based on the information indicating the interaction, to generate a modified multilayer and interactive user interface. The device provides, to the client device, the modified multilayer and interactive user interface.

Multilayer and interactive user interfaces for displaying features of an optimized network plan

Fractional Frequency Reuse Design and Techniques for WiMAX

Features related to systems and methods for network planning based on optimization modeling of equipment and item transmissions. The network planning may include a model to plan for transmission of items over a network to maximize overall efficiencies over alternative transmission modes. The model may produce a network plan that schedules transmissions, determines the number and types of equipment needed to support the transmissions, assigns equipment to specific locations, and optimally routes items throughout the network.
