Broadcast domains typically extend across an entire Wi-Fi SSID or IP Subnet. More specifically, they need to be in the same broadcast domain so that service discovery messages can be heard by other devices. Provided you’re lucky enough to have two devices that can discover each other, they then have to be on the same network to use any of the service discovery protocols we’ve discussed so far. Android implements both natively but doesn’t provide it’s own browser or basic set of tools so you’ll need to find an app to complete our proposed file transfer. Here we have our first problem: Windows and MacOS implement two different protocols, and neither implements the other. SLP an older IETF RFCs, now considered more or less obsolete. ![]() UPnP, based on, uh, Microsoft stuff, I guess, promoted by the Open Connectivity Foundation (totally not a standards group).Bonjour, based on the IETF mDNS and DNS-SD RFCs, promoted and branded by Apple.And the beautiful thing about standards is that there are so many to choose from: Thankfully there are standards for doing this. Bonne Chance!Īssuming that you and your host have some way to share files locally, and that both the client and server are on the same network, all we need to connect is to figure out what network addresses to use. Bluetooth won’t help you much, since it’s not fast enough to transfer the file in a reasonable amount of time, but if you have recent laptops you should be able to get more than a gigabit per second using the Wi-Fi Radios. The good news? Both your laptop and your hosts are equipped with the latest Wi-Fi and Bluetooth radios. And it just so happens that the internet connection in this conference room is slow, very slow something like 100 Kb/s, even if you could upload the file to a sharing site your host will have to download it again, taking twice as long… It’s not a huge file, but it’s not small either, too big for email, let’s say a whopping 100 Mb. There is a lot of money hanging on these approvals and you are anxious to get the document reviewed. You host needs to review the document before sending it on for approvals. WirelessMon can log the information it collects into a file, while also providing comprehensive graphing of signal level and real time IP and 802.11 WiFi statistics.Picture yourself in a conference room you are a visitor here, sitting in front of a laptop looking at a document that you need to send to your host, who works here. WirelessMon is a software tool that allows users to monitor the status of wireless WiFi adapters and gather information about nearby wireless access points and hotspots. For each detected network, it displays the following information: SSID, Last Signal Quality, Average Signal Quality, Detection Counter, Authentication Algorithm, Cipher Algorithm, MAC Address, RSSI, Channel Frequency, Channel Number, and more. WirelessNetView is a small utility that runs in the background, and monitor the activity of wireless networks around you. It scans 802.11 a/b/g/n/ac, both 2.4 GHz and 5 GHz bands. The tool reports signal strength in dBm and shows access point BSSID/MAC addresses. ![]() Use it for wireless site surveys, wireless discovery, and to connect to WiFi networks. WiFi Scanner detects access points and clients in ad-hoc mode if the SSID is being broadcasted. NetStumbler is a tool that detects WLANs using 802.11b, 802.11a and 802.11g. No updated version has been developed since 2005. NetStumbler helps detecting networks interference.
