Mobile device adoption is ubiquitous, although usage patterns vary by socio-economic demographic and geographic location.
- [Instructor] In the 19th century, the United States prided itself on being upwardly mobile socially as illustrated in the inspirational, rags-to-riches stories written by Horatio Alger. In the 20th century, we embraced being geographically mobile as illustrated by our deep affection for, and dependence on, automotive travel. At least in the first decades of the 21st century, we seemed to be addicted to data and communications mobility as indicated by these quick facts on international wireless living patterns assembled by the International Wireless Industry Association, CTIA, originally known as the Cellular Telephone Industries Association.
Americans use their smartphones six days per week. This number surprises me. I know my family and close friends use theirs daily. Does this match with your experience? More than 52% of worldwide digital video views will be on mobile devices in 2016, as opposed to 40% in 2014. I would love to know more about the use among different ages. My grandchildren happily watch movies on iPad screens, and seem completely unconcerned that the screen size is small.
There's some kind of magical control they can exert on these small devices. And at the same time, peace is maintained in the household as they enjoy their programs while the grownups watch their news programs. The CTIA report went on to say smartphones comprise 77% of traffic on wireless networks and 56.6% of device connections in North America. Smartphones account for 98% of the growth in digital commerce site visits worldwide.
I hope that those using smart wallet features, features like automatic bill pay, are locking down their devices. The potential for fraud with those features is high. In the U.S., 28% of millennials prefer shopping on their smartphones to using their computers. Of course this might beg the question, do millennials consider having a computer and a smartphone redundant? Banks encourage customers to use their mobile devices for financial transactions offering conveniences like digital check deposits.
Just snap a picture of your check on your mobile phone and send it. And quick mortgage approvals: one loan source even promises approval in eight minutes. According to Cisco's Visual Networking Index, VNI, a global mobile data traffic forecast from 2015 to 2020 that was released in February, 2016, 70% of the world's population will be among mobile users. That's 5.5 billion people. Cisco projects that 72% of total mobile devices and connections will be attributed to smart mobile devices by 2020.
With smart devices generating 98% of mobile data traffic, smartphones and phablets, smartphone and tablet hybrids, are predicted to be so popular that more people will own such devices, 5.4 billion, than will have cars, 2.8 billion, or electricity, 5.3 billion. Apparently, we'll also be experiencing technical innovations in rechargeable devices. Other analysts are betting that the wearables market will be worth $25 billion by 2019, a 67% increase over 2015.
Mobile devices have become essential tools in medical and fitness environments. Devices include blood glucose monitors for individuals with diabetes; heart rate, blood pressure and activity trackers; pacemakers; and pharmaceutical dictionaries. Some of these devices are passive. They record information that can then be used to identify behavioral patterns and suggest changes. Other devices are more active, directing medication dosage. All of the devices capture personal health information.
If we trust that these projections based on recent trends are reasonable, it makes sense to question just how much information could potentially be available about us as individuals. For example, personal health records and vital statistics data, geolocation tracking, social media, purchasing, travel, and financial transaction activities. Our control over such information, whether collected formally or informally, is limited. Meanwhile, its capture and storage appear unlimited.
Asserting the right to be left alone is becoming more problematic. This is a choice we need to be aware of making. It can be easy to discount the value of our information to others. In addition to those who claim a legitimate right to requesting and sharing the information trail our mobile device activity creates, there are those who explicitly use our information solely for profit. In summary, mobile devices will become even more closely integrated into our daily lives in the foreseeable future. It is useful to understand how wireless technology developed so that we can understand where weaknesses lie in wireless communication channels, as well as in the mobile devices themselves.
Next, we will look at the innovations made historically that are fundamental to wireless communications and mobile devices.
