Definition:
This indicator is defined as the percentage of inhabitants living within range of a mobile-cellular signal (2G, 3G or LTE), irrespective of whether or not they are mobile phone subscribers or users.
Concepts:
2G population coverage refers to population with access only to mobile networks with data communications at downstream speeds below 256Kbit/s. This includes mobile-cellular technologies such as GPRS, CDMA2000 1x and most EDGE implementations.
3G population coverage refers to population with access to 3G mobile-cellular signals. This includes mobile-cellular technologies such as HSPA, UMTS and EV-DO. It excludes people covered only by GPRS, EDGE or CDMA 1xRTT.
LTE population coverage refers to population with access to LTE/LTE-Advanced, mobile WiMAX/WirelessMAN or other more advanced mobile-cellular networks. It excludes people covered only by HSPA, UMTS, EV-DO and previous 3G technologies, and also excludes fixed WiMAX coverage.
Rationale and Interpretation:
Percentage of population covered by a mobile network can be considered as a baseline indicator for ICT access, as it measures the possibility to subscribe and use cellular services for communication. As mobile networks expand, more people have such subscription opportunities, thus overcoming basic infrastructure barriers exhibited by fixed-telephone (landline) networks. Disaggregation by technology (2G, 3G and LTE) offers proxy measures of access to different kinds of cellular services, such as voice only (for 2G) and increasingly high-speed access to the internet and other data-based services (for 3G and LTE). This indicator is, therefore, a direct insight into the level of digital divide prevalent in a country, and would help design targeted policies to overcome remaining infrastructure barriers.
