In 2020, revenues from the sale of connected devices and services, and revenues from related services such as pay-as-you-drive car insurance, will be worth US$2.5 trillion, of which US$1.2 trillion could be addressed by mobile operators and the remainder by the broader connected life ecosystem.
However, Internet of Things or IoE is not without the challenges. Here are some of them.
Security and reliability
IoE will face many hurdles as it comes to fruition over the next 10 years. Some of these challenges will be familiar, including security, privacy, and reliability, while other problems will require us to have open social and political discussions.
Setting protocol, standard
Many technical barriers will need to overcome as IoE pushes the boundaries of what we know is possible today with regard to network protocols, storage, and analytics.
For example, IPv6 must become a reality as the number of connections moves from billions to trillions.
Powering up the devices
Finding energy sources for powering the huge number of miniature (even Microscopic) devices. To overcome these challenges, government organizations, and standards bodies, businesses and even citizens will need to come together in a spirit of cooperation.
IoT Skill set
Lack of IoE/IoT skills and knowledge among employees and management is viewed as the biggest obstacle to using the IoT more extensively. To address these gaps, organizations are training staff and recruiting IoT talent, raising the potential for IoT talent wars.
Privacy issues
Others are hiring consultants and third-party experts, seeking to build knowledge and identify successful IoT business models. While reliability of networks is a major driving factor in IoE, privacy gets to be a key challenge because we will have to follow certain regulations prescribed by TRAI for tracking our employees.
