75 billion devices on IoT! that is huge number. But why each of these devices needs a unique IP address. Majority of these devices will be serving some local function and need not have the global reach with a static IP address.
Can some compartmentalization of these devices be done to minimize the traffic load and security threats?
Other than increased bandwidth, what constitutes 5G remains to be seen. But we do know that operators will need to upgrade their networks, as they have for 4G. RAN sharing will be integral to these upgrades, with the strongest MNOs building the necessary infrastructure and leasing selectively as needed. This prospect has been a hot topic recently, especially in Europe, and will begin to take effect in 2014.
