This work presents a performance evaluation of two of the most popular end-to-end third generation technologies. The technologies analyzed were EVDO Rev. A and HSDPA. Although these technologies are present around the world, most of the work based on these technologies is only simulation, being most of the real-case scenario investigations, internal carrier studies. We used a real-case scenario using TCP and UDP. We measured throughput, jitter and packet loss/discard as QoS performance parameters. We performed tests using both technologies concurrently with two identical computers at downlink and uplink at 0 km/h, 60 km/h and 90 km/h. These computers send/receive data to a static server host located in California. In general, we noticed that HSDPA and EVDO lose performance when speed increases.
The experimental results of the Fowler-Nordheim characterization using poly1-poly2 capacitors on CMOS ON Semi 0.5 𝜇m technology are presented. This characterization allows the development, design, and characterization of a newcurrent-mode analog nonvolatile memory. Experimental results of the memory cell architecture are presented and demonstrate the usefulness of the proposed architecture.
