Figure 3 Correlation between population and phone call intensity.
Singapore has also one of the highest local population mobile phone penetration rate (150 % in 2012), hence one can often see HCWs and patients in SHP using their personal mobile phones or landlines for communication.
In Kenya, where the government has removed its dead hand from the telecoms market, mobile phones are ubiquitous; in next-door Ethiopia, where the government's grip is as tight as ever, only 2% of the population has phones.
He notes that each new telecoms technology spreads more quickly than the last: fixed-line telephones took 50 years to reach 50% of the population, mobile phones took 20 years, the internet ten and broadband five in some parts of the world.
First, in response to the high risk factor prevalence in this population, mobile phones can be used to disseminate healthy lifestyle advice to support and motivate patients making challenging lifestyle changes.
The saturation level (the number of mobile phones per population) of mobile phones in Japan was 102.67% in 2011 [14].
Not bad for country where, two decades ago, half the population had no phone line.
About three-fourths of the population has mobile phone service, and one-fourth has internet service.
But Matthew Key, chief executive of O2 in Britain, said Edge would be available in areas covering only about 30percentt of the British population when the phone is introduced in Britain on Nov. 9.
Only 32percentt of America's population has cell phone service, according to figures from the International Telecommunication Union, compared with 45percentt in Japan, 46percentt in Britain, 54 percent in Italy, 59percentt in Sweden and 65percentt in Finland.
