Support is another issue. "There are a wide variety of device makers, application developers, and telcos supporting each component of the IoT value-chain," said Pelino. "This fragmented vendor landscape confuses IT decision makers who must determine who to call if there are issues. Should they call the device manufacturer to install or replace individual devices? What should they do when individual devices are not working?"
As most IoT offerings are developed to address requirements of a vertical market, to work on a specific device or over specific wireless networks, they make it difficult for companies to deploy nationally or internationally for fleet management or telematics, said Pelino. "In addition, national or international IoT deployment is complicated by the fact that seamless [national and international] network coverage is mostly available from multiple telcos," she observed.
The lack of standardization and regulations is also an obstacle. Vendors and service providers must work on standardizing technology platforms and develop open protocols to allow for tighter integration between sensors, devices and other hardware, said Pelino.
"Broad implementation of the IoT requires wide-scale adoption of the IPv6 protocol that offers nearly unlimited IP addresses. In addition, standard protocols will need to be designed and adopted such as MQTT," she added.
