حمد بن خليفة تطور تقنية داعمة لشبكة “لاي فاي”
DOHA: Faculty members at Hamad Bin Khalifa University’s (HBKU) College of Science and Engineering (CSE) are conducting innovative research to create a prototype in support of Li-Fi technology – a scientific breakthrough that utilizes the abundance of light to transmit data between different devices.
Currently under development, Li-Fi technology serves similar purposes to the popular Wi-Fi technology, but works by converting light intensity into binary bits that are transmitted at high-speed rates and can be understood by electronic devices, including mobile phone cameras.
Although Li-Fi technology is considered by many to be secure with minimal possibilities of disruption, CSE’s faculty are working towards a prototype that ensures continuity and security of data communication. Their research project, titled Relay-assisted Visible Light Communication, has been made possible through a Qatar Foundation research grant.
CSE’s proposed prototype will use multiple nodes such that, if one point of reception is blocked, light may be automatically rerouted to another node, thereby ensuring constant and direct transmission at all times.
Dr. Mounir Hamdi, dean of CSE, said, “Our mandate at CSE is to work on forward-thinking solutions that are oriented towards our needs in the not-too-distant future. The support we get within HBKU and from Qatar Foundation is paramount to our success in developing applications that are relevant nationally and meet pressing challenges.”
The applications of Li-Fi are vast and extend to effective and remote traffic management, where the technology may be utilized to facilitate a ‘wireless conversation’ between two vehicles with the aim of preventing collisions. Li-Fi technology also is considered to be integral to the operation of smart homes and cities.
In hospitals, Li-Fi technology becomes especially critical where the lives of patients may be contingent on seamless transmission of data. Lastly, the technology may be utilized to monitor underwater systems and examine gas pipes for any potential leaks, thereby evading catastrophic consequences.
Dr. Mohamed Abdallah, lead principal investigator of the research project, said, “Tapping into new areas of research is an overarching aim for us at CSE. All of the research we conduct today is geared towards finding real solutions with every-day applicability.”
Over the course of one year, Dr. Abdallah will be working closely with researchers at Texas A&M University at Qatar, as well as TUBITAK and Ozuegin University in Turkey, to submit the prototype for consideration. If successful, the project will move to the start-up phase.
يجري مجموعة من أعضاء هيئة التدريس في كلية العلوم والهندسة بجامعة حمد بن خليفة بحوثًا مبتكرة تهدف إلى إنشاء نموذج أولي يدعم تقنية “لاي فاي” (Li-Fi)، وهي ابتكار رائد لنقل البيانات بين الأجهزة المختلفة عن طريق الضوء.
وتعمل تقنية “لاي فاي”، التي لا تزال قيد التطوير حاليًا، على تحقيق نفس الغرض الذي تقوم به تقنية الواي فاي المعروفة، ولكنها تعمل من خلال تحويل كثافة الضوء إلى بتّات ثنائية تنتقل بمعدلات سرعة عالية، بحيث يمكن للأجهزة الإلكترونية مثل الهواتف الذكية وكاميرات الهواتف المحمولة التعرف عليها ، وقد أصبح بالإمكان إجراء هذا المشروع البحثي بعنوان “الاتصالات الضوئية المرئية بمساعدة التتابع” بفضل دعم المنح البحثية التي تقدمها مؤسسة قطر.
وقال الدكتور منير حمدي، عميد كلية العلوم والهندسة: “تتمثل مهمتنا في الكلية في العمل على تطوير حلول مستقبلية تستهدف تلبية احتياجاتنا في المستقبل القريب. وأن الدعم الذي نتلقاه من جامعة حمد بن خليفة ومؤسسة قطر له أهمية بالغة في نجاحنا في تطوير التطبيقات ذات الصلة بالبيئة المحلية ومواجهة التحديات الملحة المختلفة”.
