In Ghana and many countries within Sub-Sahara Africa, Long Term Evolution (LTE) is being considered for use within the sectors of Governance, Energy distribution and transmission, Transport, Education and Health. Subscribers and Governments within the region have high expectations for these new networks and want to leverage the promised enhanced co...

... RSRP levels were randomly distributed ranging between -50 to -140dBm for the three MIMO configurations. The receiver sensitivity required for minimum performance was obtained at -110 dBm which implies that a cell usable range of 2km was achievable using 2X2 MIMO as indicated in Fig. 6. The minimum threshold sensitivity however was -133 dBm which implies that the network can be sensed at about 3 km using 2X2 MIMO but a user will not enjoy expected throughput after 2km away from the cell ...

... main purpose of the initial planning process was to investigate and develop efficient and low cost radio access systems to provide users in an urban environment a full range of broadband services. The final radio plan in Fig. 6 for the deployed 2X2 MIMO configuration helps achieve this objective through efficient utilization of radio frequency bands and optimization of transmission capacities for the different variety of users within the pilot network. To predict the radio wave propagation in the network, the planning tool took into account the antenna ...

... of transmission capacities for the different variety of users within the pilot network. To predict the radio wave propagation in the network, the planning tool took into account the antenna radiation patterns results. Since the information used to determine the simulation parameters were obtained from the network planning engineers, the result in Fig. 6 produces similarly structured cell plans as the one being used by the network operator. The simulated radio plans in this research however achieves a coverage level above 97% as compared to the 90-92% which was obtained by the network engineers during the planning stage. The increase in the coverage level could be attributed to the ...

People in rural areas need high-speed broadband connection for various services, including e-governance, virtual class rooms, telemedicine, video-on-demand, and home entertainment. However, in order to provide broadband services, service providers must incur high deployment costs and should wait for a long time for return on investments. Long-Term Evolution (LTE) has been proposed to overcome high deployment cost, although this technology suffers from poor coverage in rural areas. Thus, massive Multiple-Input Multiple-Output (MIMO) with its favorable propagation phenomenon can be exploited as an alternative solution to boost signal coverage in rural areas. The current study compared the performance of broadband networks for Tanzanian rural areas based on massive MIMO technology and LTE. Performance comparison is confined to Reference Signal Received Power (RSRP), User Signal-Interference Noise Ratio (SINRu) and Downlink (DL) throughput metrics for 5 MHz, 10 MHz and 20 MHz channel bandwidths at 2.1 GHz and 700 MHz carrier frequencies. The results show that, in terms of RSRP and SINRu, the performance of massive MIMO network at 5 MHz is higher than that of conventional LTE networks at 10 MHz and 20 MHz. Massive MIMO network performs better at lower channel bandwidth, making it more suitable for deployment in rural areas.
