This option brought about a lot of changes especially in the usage of communication facilities. Many Nigerians that are not willing to have Internet connectivity had no option than to accept the reality on ground. This work examines the related literatures within and outside Nigeria. Thereafter, it examined the usage level and satisfaction of the users through questionnaires administering to the subscribers of different cellular networks available. The questionnaires were administered in Akure to the cellular subscribers of MTN, GLO, Airtel and 9mobile randomly. Afterwards, the data were analyzed and discussion of the results of each component of the questionnaires was done. The study revealed that MTN subscribers are more and most respondents are just using 4G services within 1 - 6 months durations. Also, the studies established that those respondents always on 4G Services are more than any other class in a day. Thus, this work established that COVID-19 pandemic brought changes to the daily activities, thus, a shift to digital life among the subscribers.展开更多
无线电频谱作为稀缺的战略资源,是无线技术发展的基础。I M T(国际移动通信)系统及无线局域网(R L A N)系统的不断发展,以及数据业务量的不断增长,对可用频谱资源提出了更高需求。6G Hz频段(5925MHz~7125MHz)是中频频率的重要组成部分,...无线电频谱作为稀缺的战略资源,是无线技术发展的基础。I M T(国际移动通信)系统及无线局域网(R L A N)系统的不断发展,以及数据业务量的不断增长,对可用频谱资源提出了更高需求。6G Hz频段(5925MHz~7125MHz)是中频频率的重要组成部分,兼顾了低频段的覆盖优势和高频段的容量优势,能够实现数千兆赫兹大带宽频谱连续分配,是广域大容量连接的最佳候选频段。以IMT系统为例,6GHz频段是对现有5G网络带宽的进一步扩展,可以满足多种不同场景需求。GSMA数据显示,截至2022年第一季度。展开更多
