TESTING METHODOLOGY
As already mentioned the performance of Powerline adapters is directly linked to the quality of the buildings electrical grid/wiring so the output speeds from such devices will most probably vary between new and old structures. Still the results recorded when testing Powerline adapters inside the same building should easily point out the best one and so to that end we used the well-known Passmark Performance Test to measure the data transfer rate in wired, wireless and Powerline modes with a fixed (for every test) distance of 15 meters between our Netgear DGN3500 Gigabit modem/router and the primary and secondary systems (30m in total between both systems). The network data transfer test was set to duration of 40 seconds and was repeated a total of 5 times after which the average numbers were recorded into our charts.
TEST RESULTS
The TPL-405E Powerline adapters may not be the fastest ones in our test but they come extremely close to the TPL-402E models also manufactured by TRENDnet.
