For many people who have been complaining about the high cost of internet connection when it comes to making WhatsApp calls, they can now heave a sigh of relief as a 26-year-old Rwandan student has made a remarkable discovery that will turn things around.
如果你经常用WhatsApp打电话你会发现这样很费流量，但是现在你可以放心因为有一个26岁的卢旺达学生要改变这个事情了。
Deodate Mugenzi, who is pursuing Information and Communication Technology at the Polytechnic Regional Center in Kigali, Rwanda has figured out a prototype that will enable WhatsApp users to make internal and international calls without the internet.
Deodate Mugenzi，在基加利，卢旺达的理工地区中心学信息与通信技术已经发明了且制造可以让Whatsapp的用户不用网路的情况下打国内和国际电话的设备。
According to a report by local news portal New Times, Mugenzi said his prototype development was driven by the fact that internet connection is expensive in most areas of Africa.
按照当地的媒体，Mugenzi决定了制造这个设备是因为在当地的网络比较贵。
The ICT student said he generated the idea of free connection in 2017, and with the only materials available to him at the time, that is, his laptop and library books on physics, he started doing his research. What helped him more, he said, was the skills he had gathered so far in class as well as the knowledge he acquired from books on physics.
他说他是2017年的时候就开始用他的笔记本，书研究这个问题。但是他说在学校所学的技术和在书上自己学的技术帮他了不少。
How the system works
The computer system operates using optic physics, mobile gadget communication techniques, and networking principles. It enables users of WhatsApp to directly call mobile phone numbers. Currently, only WhatsApp users can call WhatsApp users. This means that Rwandans and Africans, in general, will be able to communicate with their fellow Africans, especially those who use feature phones (phones that do not allow the use of popular internet services).
In order to use the platform, Mugenzi has to register the numbers of both the caller and the receiver on WhatsApp.
他的系统是用光学物理，移动设备通信技术和网络原理。他能帮Whatsapp用户直接打手机号码。目前，WhatsApp公司仅提供WhatsApp用户之间打电话，他的发明会帮人们通过WhatsApp的用户打电话给非WhatsApp的用户，连那些用非智能手机也可以通过他的设备免费打电话。
用这个服务Mugenzi需要在WhatsApp申请打电话和接电话的用户的号码。
All power to you Mugenzi~
