Another homogenised attempt to dominate the world
Any communications protocol that uses RF is open to vulnerabilities and the more complex the protocol the larger the attack surface is going to be. Imagine a scenario in a number of years time when LTE is ubiquitous and then someone discovers an unpatchable vulnerability. Yeeha the so called cyber criminals empty everyone's bank account, or a hostile country takes the opportunity to shut everything down and keep it shut down!
If everyone starts wandering about the planet festooned with LTE devices all jabbering away to each other both the spooks and the marketing boys are going to have a field day tracking your every step. This can and already is done with WiFi enabled devices WITHOUT your device even connecting to anything, it just has to be turned on. Your jabbering devices will give away so much info about you despite data being encrypted.
Where critical infrastructure is concerned (such as TETRA) we need heterogeneous systems to prevent a common mode failure that takes everything down. Safety critical system frequently deploy systems designed by different teams in order to avoid common mode failures.
LTE will no doubt infiltrate many aspects of life either by design or simply by reduced cost and become ubiquitous by default.. The ultimate cost to society could me massive, nature abhors homogeneity for good reason.
May the Borg be with you :-)
