This Bachelor’s Thesis studied the design of a low cost UHF RFID Reader. The goal was to get a low cost design; each decision made during this thesis project followed this idea. The thesis is divided in two parts, clearly differentiated but still related to each other, as it is explained below.
A requisite of the UHF RFID Reader is having Ethernet interface, so this solution is treated after the first part. In other words, the first part of this thesis focuses on the Radio Frequency Identification world while the second part concentrates on computer networks and microcontroller programming.
The aim of the first part (chapters 1-3) is to give a general view about the design of a low cost UHF RFID Reader. So a high level design is used to explain what the reader hardware design as well as the main materials and components would
be like. In addition, the use of each element involved in the reader design has been explained and justified for a better understanding of the design.
The second part of the thesis (chapters 4 and 5) focuses on the Ethernet interface. To carry out this part of the project, a microcontroller and an Ethernet controller were used in such a way that by connecting an Ethernet cable to a computer a communication test was carried out. For this reason, a TCP/IP stack was coded to allow making a ‘ping’ between both systems (computer and Ethernet Interface). This part has been documented at the end of this thesis.
