The continuous evolution of technology, electronics, and software along with the dramatic decrease in the cost of electronic devices has led to the spread of sensing, surveillance, and control devices. The Internetof- Things (IoT) benefits from the spread of devices (things) by processing device feeds using Machine-to- Machine (M2M) technologies. At the heart of the M2M technologies lies the ability of devices (things) to identify their own location on the globe or relative to known landmark. Since location awareness is fundamental to processing sensing and control feeds, it has attracted researchers to identify ways to identify and improve location accuracy. The article looks at Global Positioning Systems (GPS) along with the enhancements and amendments that apply to satellite based solutions. The article also looks at medium to short-range wireless solutions such as cellular, Wi-Fi, Dedicated Short-Range Communications (5.9 GHz DSRC) and similar solutions. In this article define the physical limitations of current system, we define situation where every particular system underperforms and elaborate the downfalls pertaining to inherent characteristics of the proposed technology.
