v8 v9 19 19 === Experimental Setup === 20 20 21 While all of the example code provided by this application note will operate over-the-air with antennas, we chose to use RF cabling with attenuators to make the results repeatable and easier to discuss.21 While all of the example code provided by this application note will operate over-the-air (OTA) with antennas, we chose to use RF cabling with attenuators to make the results repeatable and easier to discuss. 22 22 23 23 || [[Image(wiki:802.11/wlan_exp/app_notes/dcf_with_multiple_flows/figs:experimental_setup.png, width=400)]] || [[Image(wiki:802.11/wlan_exp/app_notes/dcf_with_multiple_flows/figs:experimental_setup_photo.jpg, width=400)]] || … … 35 35 == Experiment 1: Symmetric and Fully Connected == 36 36 37 In this first experiment, we aim to see how the 802.11 Reference Design behaves when all nodes are "fully connected" with nearly-matched path losses between every combination of nodes. Topologically, this mimics the scenario where each of the three nodes sit on the vertex of an equilateral triangle. 38 39 ==== Experiment Details ==== 40 * Attenuation 1: 45dB 41 * Attenuation 2: 15dB 42 * Attenuation 3: 15dB 43 * Packet Length: 1400 byte payloads (1428 bytes OTA with MAC header and FCS) 44 45 === Baseline: Performance of Each Flow in Isolation === 46 47 As a first cut, 48 49 37 50 == Experiment 2: Symmetric with Hidden Stations == 51 52 ==== Experiment Details ==== 53 * Attenuation 1: 0dB 54 * Attenuation 2: 60dB 55 * Attenuation 3: 60dB 56 * Packet Length: 1400 byte payloads (1428 bytes OTA with MAC header and FCS) 38 57 39 58 == Resources ==
