Telecommunications experts drawn from the Nigerian Communications Commission (NCC) have explained the choice of C-Band for the impending national rollout of 5G – on a radio frequency band between 3.5 and 3.8 GHz.
The NCC team mounted the FutureNow Stage of the Innovation Pavilion of the AfricaNXT 2022 to inform, educate and rally further support for the Commission’s strides on the preparedness of Nigeria to deploy the Fifth Generation (5G) network and services.
The well-attended panel discussion, which focused on, “Moving Forward Steadily: Socio-Economic Significance of Development of 5G Services” was moderated by NCC’s Head of Online Media, Dr. Omoniyi Ibietan. Other panelists are: Babagana Digima, Team Lead, Nigeria Office for Developing the Indigenous Telecoms Sector (NODITS); Usman Aliyu, Head, Space Services; Anthony Ikemefuna, Head, Fixed Networks and Converged Services; and a Senior Manager in the Legal and Regulatory Services Department of the Commission, Dr. Mohammed Suleh-Yusuf.
According to the experts, studies show 5G needs spectrum across low, mid and high spectrum bands to deliver widespread coverage and support a wide range of use cases.
All three ranges have important roles to play: – Low-bands (e.g. sub-1 GHz) support widespread coverage, including indoors, across urban, suburban and rural areas.
Therefore, increased low-band capacity is required to create greater equality between urban and rural broadband connectivity and address the digital divide.
– Mid-bands typically offer a good mixture of coverage and capacity benefits. The majority of commercial 5G networks are relying on spectrum within the 3.3-3.8 GHz range.
According to GSMA report, other bands which may be assigned to, or refarmed by, operators for 5G include 1500 MHz, 1800 MHz, 2.1 GHz, 2.3 GHz and 2.6 GHz.
However, more spectrums will be needed to maintain 5G quality of service and meet growing demand in the longer term (e.g. 3.3-4.2 GHz, 4.8 GHz and 6 GHz).
C-band refers to the portion of the electromagnetic spectrum allotted for satellite transmissions in the 4GHz to 8GHz frequency range. C-band satellite antennas are used frequently in areas of the world where signals can become degraded due to heavy rain or other intense climate-related conditions.
Recall that prior to the 5G licencing, NCC signed a Memorandum of Understanding (MoU) with the Nigerian Communications Satellite (NIGCOMSAT) Limited to leveraging C-Band Spectrum for 5G services.
AfricaNXT Conference 2022:
The AfricaNXT Conference 2022, known previously as Lagos Social Media Week, has ended on a historically impressive note for the Nigerian Communications Commission (NCC), having drawn the largest attendance and participation at a single session during the conference, where its team discussed the socio-economic benefits of 5G services.
The conference had scheduled over 200 sessions and about 400 speakers. However, NCC session was oversubscribed as all seats were occupied, while some participants had to stand to listen to the discussion on a topic that patently enthused and electrified the audience, and marked by very rare social networking and participation.
Preparedness of Nigeria to deploy the Fifth Generation (5G) network and services
Using simple, fact-based examples, the NCC’s 5-man panel, provided necessary clarifications to the audience on the safety of 5G technology and gave copious examples about how the technology will significantly impact life qualitatively and bring socio-economic benefits to the citizens, businesses, the nation, and the continent of Africa.
The panelists extensively discussed 5G technology, focusing on safety, data privacy, the chronology of programmes, actions and activities of the Commission towards the launch of the services, including the issuance of 3.5 gigahertz (GHz) spectrum and licence for 5G deployment, the rollout plans, use cases as well as citing concrete socio-economic significance of the expected services.
The NCC team explained to the excited audience how 5G will power a plethora of applications, innovation and creativity.
These include smart cities, telemedicine, Internet of Things (IoT), smart agriculture, driverless cars, bolstering of the security governance sector, among others.
The team asserted that 5G is a network of networks because of its huge capabilities, and its derivable benefits can only be limited if humans limit their own imaginations.
Reckoning that 5G technology is a total shift from the internet connectivity people are used to at the moment, the panel stated that 5G would open doors of new possibilities and socio-economic impacts.
“With 5G, there is something for everyone. Nigeria is kick-starting these massive benefits with enhanced broadband. 5G will bridge the fibre connectivity gap and with wireless broadband connectivity, Nigerians will enjoy the enhanced broadband.”
A member of the panel stated to emphasize enhanced connectivity that comes with 5G technology.
The discussants also agreed that telecom operators will reap huge benefits from 5G in many ways, through network slicing, new revenue streams from IoT, industrial applications, gaming and entertainment as well as live broadcast features supported by 5G amongst others.
The NCC team comprising specialists in engineering, law and communications, also said that 5G will power more than a billion devices in the next two years, and this means there will be upsurge in the manufacturing of related user equipment which is expected to bring down the prices of associated devices and equipment.
The process is also expected to trigger utilisation of raw materials such as rare earth metals that are found in large quantities in Africa, and cities will equally benefit from the 5G enabled infrastructure such as smart street lighting, smart traffic control systems, maintenance services and so on that will deliver huge economic gains.
Explaining NCC’s efforts and plans on consumer safety in the 5G era, discussants recalled that the Commission was already working closely with the Office of the National Security Adviser (ONSA) to develop a Risk Management Frameworks.
The framework will grow the need for the ethical hacking skill set and allow the use of ethical hacking as part of risk management towards ensuring the cyber space safety during 5G era.
Additionally, the panel informed the audience that NCC had established a sectoral Computer Security Incidents Response Team (CSIRT) to work with the telecoms operators to reduce risks on the cyber-attacks and data breach.
The Centre, inaugurated in 2021, has been collaborating with the national agency, the Nigerian Computer Emergency Response Team (ngCERT), towards enhancing the security of the cyber space and privacy of citizens.
These strategic collaboration, for which NCC is noted, will now be boosted by the Nigeria Data Protection Bureau, recently established by the Federal Government.
While explaining the security, safety and speed characteristic of 5G, the panel reasoned that, while 4G has a response time of 10 millisecond, equivalent of the capacity of human brain, 5G network is even faster. Therefore, the high-speed feature of 5G will make it unlock greater opportunities that will enhance human productivity for the development.
“The latency of 5G, which measures its response time, is 1 millisecond, while that of 4G is measured at 10 milliseconds. While 4G can accommodate 100,000 device connections in one square kilometre, 5G can connect a million devices within the same space, and thus, power Internet of Things (IoT).
Also, 5G peak data rate is 20 gigabits (GB) per second for download, and 10GB for upload, which is higher than 100 megabytes (MB) per second download and 50MB upload offered by 4G network.”
The panel allayed fears of health concerns, propelled by “misconceptions, disinformation, misinformation and malinformation”.
The panel informed the participants that the apprehension was unnecessary. It cited research-based evidence from the World Health Organization (WHO), International Telecommunication Union (ITU), and the International Commission on Non-Ironising Radiation Protection (ICNIRP), to prove the safety of 5G network to human health.
The panel explicated further that Nigeria can indeed begin to create smart cities, an ecosystem powered by 5G applications.
The massive speed of 5G, according to the discussants, will also enhance the capacity of start-ups and other tech entrepreneurs to leverage the enabling environment powered by the fast connectivity, to develop unlimited solutions for the benefit of Nigeria and her citizens.
According to the panel, an enhanced broadband that allows low latency and facilitate billion of connections in machine-to-machine communication certainly holds a big promise for socio-economic growth and development.
When asked if the country was ready for 5G, the panel declared that, “Nigeria is ready for 5G because the NCC has been supported by key stakeholders to make Nigeria ready. The Commission has built the regulatory foundation, the deployment plan has been designed and various exercises have been carried out up to the level of handling over 5G Spectrum licences to the operators.”
Meanwhile, the panelists also emphasized the centrality of collaboration among state and non-state actors to drive the ecosystem.
They contend that, as with other previous technologies, such as 1G, 2G, 3G and 4G, efforts must be made for all stakeholders to glean and exploit the massive use cases of 5G for socio-economic development.
While rounding off the highly engaging session, the moderator thanked the co-panelists for their diligence and painstaking engagements, and the audience for its interest, enthusiasm and solidarity.
He reiterated the unflinching commitment of NCC to doing all within its regulatory powers to ensure data security and data protection.
He also underscored the need for sustenance of collaborative efforts among tiers of government and all other stakeholders to ensure effective utilization of 5G services across all sectors.
