  1. Describe the first generation Wireless Cellular Networks.
  2. What has been the driving force that motivated service providers to look for improved performance through new technological transmission applications that have resulted in second generation systems, and now even third generations sytems?
  3. Describe the major improvements in the first and second generation systems that have resulted in more capacity and better service.
  4. What are PN Sequences?
  5. How are PN codes generated?
  6. Let us look at how the Linear Shift Register is used to generate PN Sequences or PN codes.
  7. Let us look at the resulting PN Sequence when connecting Tap # 2 and Tap # 3 to the input of the Modulo-2 adder.
  8. What is the maxium length of PN Sequences?
  9. What are the characteristics of the Short PN Code?
  10. What are the characteristics of the Long PN Code?
  11. Let us look at some useful PN Codes properties.
  12. What is meant by "Correlation of Sequencies"?
  13. Let us look at an example of Correlation of Sequencies.
  14. What are the characteristics of Full Length Auto-Correlation?
  15. What is the meaning of "Orthogonal Sequences"?
  16. Let's test our knowledge of Correlation by participating in a Correlation Workshop
