Final answer:
Wireless networks have revolutionized communication and economic activities in the developing world, especially in Africa, by enabling access to mobile banking, supply chain connections, and educational resources without the need for extensive traditional infrastructure.
Step-by-step explanation:
Wireless networks play a pivotal role in the developing world, enabling communities to leapfrog the traditional infrastructure setup stages. This is particularly evident in regions like Africa, where wireless technology has expanded communication capabilities in places without landlines, leading to significant advantages in various aspects of life and economic activities.
Small-scale farmers and traders can now use mobile phones for banking, thus facilitating financial transactions without the need for physical banking infrastructure. They can also connect with suppliers and customers, which was previously hindered by limited connectivity. Schoolchildren in areas devoid of libraries can now leverage the internet to access educational resources, thus bridging some of the gaps in education. Moreover, shared-phone programs in villages enhance community access to these technologies.
The move to bypass traditional Local Area Networks (LANs) and physical cabling is often due to the lack of infrastructure and the lower costs associated with setting up wireless networks. Thus, the switch to wireless system architecture presents not only an economical solution but also accelerates access to digital resources and global connectivity.
