![]() So the strength of internet speed should be desirable. For a Modena Hub WiFi infrastructure, it’s best to start with 40 MHz channels.Our daily life now depends on the internet. This offered more throughput, just like a 4-lane highway accommodates more traffic than two lanes.Ĩ02.11ac expanded on this concept by offering 40, 80, and even 160 MHz channels via channel bonding. ![]() Channel Bonding in 802.11n and 802.11ac allows multiple 20 MHz channels to be combined to make a 40 MHz channel. ![]() For this reason and because of the higher throughput available, 5GHz is preferable over the 2.4GHz band and is required when using Modena Hub.Ĭhannel width varies depending on the wireless standard being used. The 5 GHz band has up to 25 non-overlapping channels available, depending on local regulations. Putting two networks on partially overlapping channels will result in interference, so the recommended solution is to use the three non-overlapping channels: 1, 6, and 11. Unfortunately, most of the channels partially overlap. In the 2.4 GHz band, we have 11 or 14 channels (depending on local regulations). WiFi signals are transmitted on different frequency ranges called channels. The program reports errors, packet loss, and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard deviation of the mean.Ī reasonable Ping measure between the user device and the Modena Hub should reside within few milliseconds to be within the average latency of a common LAN. Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP echo reply. A fast ping means a more responsive connection, especially in applications where timing is everything (like real time streaming). Ping measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source and gives the the reaction time of your connection–how quickly your device gets a response after you've sent out a request. Ping is a network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and is available for all operating systems. SNR should be stable above 25dB, recommended above 35dB for real time audio video streaming. When devices are far away from each other, or if there is a lot of background noise, they’ll fall back to slower and slower data rates.įor example, if RSSI is -60dBm and Noise is -95dBM, the SNR is (-60dBm) - (-95dBm) = 35dB It indicates the "intelligibility" of the message and is used to negotiate the uplink speed between the AP and the user device. The higher the SNR, the faster the connection speed. Devices constantly adjust their data rates to help the receiving device on the other end understand them. SNR: "Signal to Noise Ratio" is the difference between the RSSI and the noise level measured on the user device. ![]() RSSI should be stable above -65dBm, recommended above -60dBm for real time audio video streaming. RSSI: "Received Signal Strength Indicator" is the power of the signal received on the user device from the access point.Additional 4 Mbps average / 15 Mbps peak for the videoconference host when using the Wireless USB feature.4 Mbps average / 15 Mbps peak per connected client (upstream when presenting downstream when receiving).The minimum stable bandwidth requirements for a Modena session are: Bandwidth: the connection speed between the AP and the user device.The wireless requirements are expressed through three values: Refer to the Modena Network Administrator’s Guide for the Modena overall requirements and specific Wifi requirements. ![]()
