**8. Conclusions**

The objective of this chapter is to provide the fundamentals of UWB transceiver systems so that the general readers can be able to easily grasp some of the ideas in transceiver design for ultra-wideband communications. The chapter briefly describes signaling and modulation techniques, UWB transceiver system architecture, UWB antennas. Devices used for this exciting technology have become small, low power and low cost which in turn will accelerate their widespread use in indoor communications.
