Project Summary: In this project, we aim to design, a high-speed, low cost, Free Space Optics (FSO) link that will be capable of providing high-speed broadband internet for 5G/LTE mobile applications in urban areas.
Specific Requirements of the Project
Matlab, Design of analogue and digital electronics, signal processing and FPGA
Project Aims and Objectives
One of the main challenges in highly populated urban areas such as in city centres is to provide high-speed mobile internet access to the end mobile users. These vital urban areas are the hub of businesses, offices, transport, hospitals, campuses and social activities. However, as the population and number of mobile users in these urban areas are increasing at a very high rate. For example cisco system has predicted that due to the increasing population in urban areas the mobile data traffic has reached 2.5 exabytes (2.5 billion GB) per month by 2014, and is projected to increase by nearly 9-fold by 2019. This dynamic growth of mobile communication users is one of the most important motivations that have led to 4th generation- long term evolution (4G-LTE) and currently the global race for the development of fifth generation (5G) mobile networks.
In 4G LTE mobile communication, currently, the base station are connected with radio or microwaves frequency bands, which are already congested and hence the speed of 4G LTE systems are already slowed dramatically since they were launched two years ago. To enhance the mobile internet speed to the end users in urban areas. Modern and expensive fibre optics based infrastructure is required to connect the mobile base stations using radio over fibre links. Also, to lay down the fibre in busy urban streets particularly in city centres is not easy as it requires to trench roads and hence this can create infrastructural problems on the top of other road works. Therefore, in this project a radio over free space optics (RoFSO) is proposed. RoFSO is a low cost, energy efficient optical wireless communication system that will be capable of providing high speed links (100 Gb/s) to connect mobile base stations without the need of fibre cables and trenching the roads. RoFSO is a new and emerging FSO based technology that uses the optical spectrum (via lasers or LEDs) to transmit high-speed mobile network traffic wirelessly for outdoor applications.
