Range is determined by the sensitivity of the transceiver and its output power, commonly referred to as link budget. A primary factor affecting radio sensitivity is the data rate. The lower the data rate, the narrower the receive bandwidth is and the greater the sensitivity of the radio. Figure 18 shows how sensitivity is higher at lower data ratee.
GNSS Augmentations and Other Navigation Satellite Systems

Pseudolites are ground-based radio transmitters that transmit a signal of a GNSS. They act like a navigation satellite, but from the earth’s surface. Pseudolite is a contraction of the terms pseudo and satellite, used to refer to something that is not a satellite but which performs a function commonly in the domain of satellites. Pseudolites are most often small transceivers that are used to create a local, ground-based GNSS alternative. A transceiver is a device that has both a transmitter and a receiver in a combined form and share common circuitry or a single housing. The range of each transceiver’s signal is dependent on the power available to the unit.

A transceiver is a device that transmits and receives various forms of signals using a common circuitry. Cellular networks and devices employ transceivers that provide transmission and reception simultaneously but on separate frequencies, that is in full duplex mode.

Nowadays, generally, portable wireless devices are powered by batteries. Batteries have a limited life. Moreover, these devices’ maintenance becomes a significant challenge in remote locations; thus, energy-efficient, small-sized portable wireless devices are in great demand in modern communication [1,2]. In these devices, one of the most decisive subsystems in terms of performance requirements is the transceiver. It requires a continuous power supply for reliable communication among them. Therefore, architecture selection and minimization of power consumption of its sub-blocks while maintaining its performance parameters are critical issues for successful system implementation. Recent progress has been made in the wide range of IoT applications such as health care, smart home applications, smart wearable, etc. Generally, the “Things” in IoTs are small battery-powered device that includes a transceiver to connect wirelessly to the internet [3,4]. There are two approaches for analog VLSI design to achieve low voltage and low power; the first is fabrications technology optimization, and the second one is to optimize the design's architecture within the available fabrication technology. This work deals with the second approach.
