Q. Consider the following statements:
1.The Access Network (AN) of a cellular network has equipment that provides connectivity to other networks, such as the Internet.
2.The Institute of Electrical and Electronics Engineers (IEEE) 2061-2024 standard includes various types of base stations, such as macro-BS for large coverage areas and Wi-Fi for high-speed connectivity within villages.
Which of the statement(s) given above is/are correct?
Explanation –
Statement 1 is incorrect. A cellular network can be divided into two sub-networks: the Access Network (AN) and the Core Network (CN). The AN consists of base stations that provide wireless connectivity to mobile devices in a limited geographical area, called the coverage area. The CN of a cellular network has equipment that provides connectivity to other networks, such as the Internet. Unlike AN base station, the CN operates in a central location, and possibly far from any of the base stations.
Statement 2 is correct. The IEEE-2061 standard includes a heterogeneous Access Network (AN) with different types of base stations coexisting. It mentions macro-BS for large coverage areas and Wi-Fi for high-speed connectivity within villages.
