The current digital age has made good internet access via wireless internet a prerequisite in residential homes, offices, learning institutions and in the streets. Most of the traditional Wi-Fi networks are known to have limited coverage, poor signal strength, and dead zones especially in the large or multi-storey buildings due to their use of single router or access point. These problems are also enhanced by physical barriers, interference of the signal, and the emergence of more users with connections, thus making the sustainability of the connectivity a challenge.The given project is going to enhance the functionality of wireless networks by deploying a Wi-Fi mesh network infrastructure. A Wi-Fi mesh network is a network comprised of several connected wireless nodes working as one network altogether. In contrast to traditional Wi-Fi networks, mesh networks can help in multihop communication and dynamic routing so that the data could be relayed by more than one of the existing paths. This will increase network reliability, fault tolerance, and be able to self-heal, so that even in the event of a node failure, it will not interrupt the connectivity.Mesh nodes in the proposed system are spacially placed throughout the coverage area to remove the dead zones and give a consistent signal strength. The intelligent routing systems keep a constant watch on the network conditions including signal quality and load to choose the best data transmission routes. Performance analysis indicates that mesh network is much better in terms of coverage area, throughput, stability and latency compared to single-router Wi-Fi system. In general, the given Wi-Fi mesh network has the potential to be a scalable, reliable, and efficient solution that can be applicable to the contemporary homes, offices, campuses, and large residential areas. It is responsive towards new wireless needs in terms of longer durability and greater flexibility.
