Performance Analysis of a 5G Transceiver Implementation for Remote Areas Scenarios

Abstract

Fifth generation of mobile communication networks will support a large set of new services and applications. One important use case is the remote area coverage for broadband Internet access. This use case has significant social and economical impact, since a considerable percentage of the global population living in low populated area does not have Internet access and the communication infrastructure in rural areas can be used to improve agrobusiness productivity. The aim of this paper is to analyze the performance of a 5G for Remote Areas transceiver, implemented on field programmable gate array based hardware for real-time processing. This transceiver employs the latest digital communication techniques, such as generalized frequency division multiplexing waveform combined with 2 by 2 multipleinput multiple-output diversity scheme and polar channel coding. The performance of the prototype is evaluated regarding its outof-band emissions and bit error rate under AWGN channel.

5G for Remote Areas: Challenges, Opportunities and Business Modeling for Brazil

“…For our analyses, we have assumed that a 5G system can provide broadband rural connectivity at 50 km distance from the Base Station (BS). Some works show that there are already solutions available to meet such a requirement [26], [27]. In [26], a 5G system based on 3rd Generation Partnership Project (3GPP) technologies was proposed for providing a high-capacity and long-range cost-efficient solution.…”

“…Such a system operates in mid-band (3.5GHz) and makes use of high towers and high-power BSs. Another innovative solution is the one proposed in [27], called [28], and uses a Cognitive Radio (CR) approach, where up to 24 MHz can be aggregated to provide up to 100 Mbps at 50 km distance from the BS. Since the use of TVWS dovetailed with 5G infrastructure for rural coverage has been presented as a promising solution for yielding cost-effectiveness from a service provider's perspective [29], we have considered the 5G-RANGE network as our adopted 5G solution, where four core use cases are targeted:…”

Enhanced Remote Areas Communications: The Missing Scenario for 5G and Beyond 5G Networks

“…The use of high frequency bands and small cells in 5G networks hinder the development of an important scenario for continental size countries, which is the eRAC [19]. In fact, the main scenarios addressed by the current 5G networks development are antipodal to what is needed to provide reliable and high quality broadband mobile networks in remote and rural areas, which is the missing scenario to be covered by Beyond 5G networks (B5G).…”

“…The shared spectrum approach is receiving support from regulators and will allow communities and small operators to organize and deploy a local network without going through the spectrum auction process [20]. Another approach that is currently being considered by the Remote Area Access Network for the 5th Generation (5G-RANGE) project [19] consists on allowing local and rural operators to exploit unused TV channels, also known as TV White Space (TVWS), as secondary network. In this case, a cognitive engine [21] must be used to identify the spectrum opportunities where the network can be deployed and also to coordinate the spectrum change when a Primary User (PU) is identified in the frequency used by the secondary network.…”

Indoor Coexistence Analysis Among 5G New Radio, LTE-A and NB-IoT in the 700 MHz Band

“…The fifth generation of mobile communication (5G) is going to operate over two frequency ranges, namely: FR1 from 410 MHz to 7.125 GHz with bandwidth up to 100 MHz; FR2 from 24.25 to 52.6 GHz with bandwidth up to 400 MHz. As a consequence, coexistence analyses with 4G and 5G systems are mandatory [2][3][4].…”
