چکیده
پهنای باند سیار از زمان استفاده از آن در آفریقا توانسته سود اجتماعی و اقتصادی را برای مردم آفریقا به ارمغان بیاورد. افزایش مهاجرت به خدمات پهنای باند تلفن همراه در آفریقا به دلیل افزایش نرخ پذیرش گوشی های هوشمند، افزایش گسترش شبکه و ترجمه به فناوری های جدید و سریعتر است. از آنجایی که رشد فناوری نقش اساسی در جامعه ایفا می کند، نیاز به ارزیابی مستقل و بی طرفانه از کیفیت خدمات ارائه شده توسط زیرساخت پهن باند تلفن همراه وجود دارد. با این حال، کار کمی بر روی بررسی سیستماتیک و مداوم نظارت، تحلیل، ارزیابی و گزارش عملکرد پهنای باند تلفن همراه در آفریقا انجام شده است. این مقاله یک تحقیق کامل در مورد روشهای به کار گرفته شده برای اندازهگیری، نظارت و آزمایش شبکه پهنباند تلفن همراه سرتاسر ارائه میکند. سیاست ها و توصیه ها بر اساس درس های آموخته شده پیشنهاد می شوند. از جمله این توصیهها، حمایت از استفاده از رویکرد اندازهگیری مبتنی بر میزبان برای مطالعه مداوم عملکرد پهنای باند تلفن همراه برای کمک به سهامداران مختلف برای تصمیمگیری آگاهانه است. علاوه بر این، مشخص شد که سرعت پهنای باند رضایتبخش تنها عاملی نیست که کیفیت خدمات پهنای باند را محدود میکند، و در نهایت، تغییرات قابل توجهی در سرعت پهنای باند برای همان سرویس در طول زمان به دلیل چندین عامل پیچیده مرتبط با روش ها و شرایط مختلف اندازه گیری

Abstract
Mobile broadband since its adoption in Africa has been able to deliver both social and economical dividends to the African people. The increased migration to mobile broadband services in Africa is due to accelerated smartphone adoption rate, increased network roll-out and translation to new and faster technologies. Because technological growth plays a substantial role in society, there is a need for an independent and unbiased assessment of the quality of service offered by mobile broadband infrastructure. However, little work had been carried out on the systematic and consistent investigation of mobile broadband performance monitoring, analysis, evaluation and reporting in Africa. This paper presents a thorough inquiry into the methods employed for end-to-end mobile broadband network measurement, monitoring and experimentation. Policies and recommendations are proposed based on the lessons learnt. Amongst these recommendations is advocacy for the use of a host-based measurement approach for the continued study of mobile broadband performance to assist the various stakeholders to make informed decisions. Furthermore, it was brought to the fore that unsatisfactory broadband speed is not the sole factor that limits the quality of broadband service, and, lastly, significant variations in broadband speed for the same service can be recorded over time due to several complex factors relating to different measurement approaches and conditions.
Introduction
The mobile industry which connects over 3.5 billion people globally to the Internet and more than half a billion people in Africa is the largest Information and Communications Technology (ICT) in history (Bahia and Suardi 2019). Mobile broadband has not only meaningfully extended the reach of the Internet over the past decade but also has actively become the fundamental method of communication for people around the globe (Bold and Davidson 2012). To ensure that everyone, everywhere has access to the Internet with all its opportunities, accelerated work must be done to tackle the inherent challenges that might be encountered. Policies must be put in place to reduce the cost to connect and realize affordable universal access. At the same time, the quality of service (QoS) that online populations encounter when they connect to the Internet must be considered (Woodhouse and Thakur 2018).
Conclusion
Having detailed performance monitoring and analysis of today’s ever-growing and complex mobile broadband networks is a very difficult task that requires the concerted efforts of all stakeholders. This is important in bringing about the adoption of universally acceptable tools and the execution of large-scale and long-term monitoring processes. No method or approach can be adjudged the best or the worst when it comes to network monitoring, as each approach comes with its own advantages and limitations. However, the ability to obtain fine-grained measurement results from diverse locations, devices and operators/ISPs, and is what determines the robustness of the monitoring effort. This survey has presented a detailed overview and comparison of the various approaches employed to date to measure the end-to-end performance of broadband networks. Several existing projects which produce different network services and tools were also explained and explored.
