The most recent annual mobility report compiled by Swedish telecommunications equipment maker Ericsson projects that the total number of mobile subscriptions worldwide will exceed the global population in 2015. Released on Tuesday, the report points to a year-over-year growth rate of 7% for global mobile subscriptions that includes 120 million net additions during the first quarter of 2014 alone. At that rate, total mobile subscriptions will surpass the world’s population by next year. Within two years, global wireless smart phone subscriptions are expected to surpass basic mobile service subscriptions and reach an estimated 5.6 billion subscriptions worldwide by 2019. Wireless broadband subscriptions, meanwhile, are projected to reach 7.6 billion by the end of 2019 to account for more than 80% of total mobile subscriptions. One factor driving this growth is the developing market for machine-to-machine (M2M) connectivity— more popularly known as the “Internet of things”—which is expected to quadruple in size by 2019. Although most M2M devices are today powered by wireless GSM technology, Ericsson estimates that more than 20% of active M2M devices will be connected to fourth-generation LTE subscriptions by 2019. Observing that, “over time, cellular M2M services and applications . . . will require very short latency in order to be efficient, Ericsson Chief Strategy Officer Rima Qureshi told reporters: “we also see device-to-device and [M2M] applications as a key focus” of future fifth-generation wireless networks.
