“…Mobile communication technologies have steadily evolved from the first generation (1G) analogue communication systems to the recently deployed superfast and ultra-reliable fifth generation (5G) system. However, the journey to realizing MBB performance began with the adoption of second generation (2G) mobile communication systems, which were first deployed in 1991 [5]. These systems were progressively improved and this led to 3G, 4G and today's 5G networks respectively.…”

Even though the proliferation of handheld mobile communication devices has deepened Internet and broadband penetration in Nigeria, users of such services may not have detailed quantitative performance comparison between the services provided by different network operators. The study here reported is therefore an attempt to bridge the information gap. A measurement testbed based on the Raspberry Pi platform was developed to autonomously measure the mobile broadband performance of third generation (3G) and fourth generation (4G) broadband networks of the four major mobile network operators in the country. Under static access conditions, the system was set up to measure the upload throughput, download throughput and latency from a user-centric perspective. The measurements were taken by simultaneously sampling the networks of four mobile broadband service providers (9Mobile, Airtel, Globacom and MTN) over a period of three weeks in the city of Uyo, Nigeria. The results obtained revealed that Airtel achieved the highest peak download rate for 3G throughput, and this was only 1.41 Mbps higher than the least performing MNO. Also, it was found that MTN’s download rate peaked at 35.06 Mbps, and this was over 300% of the rate achieved by the fourth rated network in terms of the 4G download throughput metric. The measurement results also revealed that peak usage periods, defined as the hours between 7pm and 11pm, witnessed higher variability in throughput rates than other periods.

“…GSM is considered in this work as case study to demonstrate the concepts. The reason GSM is chosen for this study is that it is the most widely deployed digital cellular standard having over 2 billion users in about 210 countries while adding 1000 every minute and thus constituting a largest share of today's telecom market [2] [3]. This paper presents the study performed to evaluate the capacity, performance and cost of MCN for their three different architectural configurations.…”

Multihop Cellular Networks (MCN) have emerged as promising solution to cope with the time persistent problem of poor cell edge and indoor coverage offered by Conventional Cellular Networks (CCN). Furthermore, having potential to increase system throughput and performance while decreasing deployment cost, MCN are being envisioned as essential part of future broadband networks. In prospective of these futuristic trends, this paper addresses the dire need to assess different MCN architecture options and quantify the gains they offer in terms of capacity, performance and system cost compared to CCN. As the first standard for MCN i.e. 802.16j is on the way yet, this paper relies on the most well known example of CCN i.e. GSM to demonstrate the concepts in this study and evaluates the realistic capacity and performance of three different architectural options for MCN. These are : 1) MCN without spectrum sharing between Base Station (BS) to Relay stations (RS) and RS to Mobile Station (MS) links. 2) MCN with spectrum sharing between BS-RS and RS-MS links, and 3) MCN without out spectrum sharing while BS's acting as umbrella cells on top of RS's. Results show the MCN, depending on the their configuration, in addition to improved Grade of Service (GoS ) can yield 34% to 170% higher system capacity for a 50 to 67% more system cost compared to an optimised CCN.I.
