As a long term trend, communication costs have dropped, and likely will continue to drop, for a number of reasons:
- Moore’s Law
- Better technology (mobile, fixed, device, radios and network infrastructure)
- Competition
- Manufacturing efficiencies
The impact also can be quite substantial over short periods of time. Consider the retail price of mobile data in Asian and African countries over the past several years. Where mobile data in 2015 might have eaten up four percent of monthly income in Nigeria, gby 2017 mobile data had fallen to consume about 0.75 percent of monthly income.
