    The interface is a real-time dashboard of signal strength, available networks, and other metrics. It has been used to assist with the relief efforts in Ebola affected regions. [13] Using the data collected from the Opensignal app, the company is building WifiMapper, [14] an app for finding free Wi‑Fi hotspots, available on iOS and Android.

  3. Measuring network throughput - Wikipedia

    en.wikipedia.org/wiki/Measuring_network_throughput

    Its advantage is that it is simple — it can be implemented using only three wires: Send, Receive and Signal Ground (or Signal Common). In an RS-232 interface, an idle connection has a continuous negative voltage applied. A 'zero' bit is represented as a positive voltage difference with respect to the Signal Ground and a 'one' bit is a ...

  4. Mobile phone signal - Wikipedia

    en.wikipedia.org/wiki/Mobile_phone_signal

    A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink). Depending on various factors, such as proximity to a tower , any obstructions such as buildings or trees, etc. this signal strength will vary.

  5. Signal strength in telecommunications - Wikipedia

    en.wikipedia.org/wiki/Signal_strength_in...

    Weak signal strength can also be caused by destructive interference of the signals from local towers in urban areas, or by the construction materials used in some buildings causing significant attenuation of signal strength. Large buildings such as warehouses, hospitals and factories often have no usable signal further than a few metres from ...

  6. Network analyzer (electrical) - Wikipedia

    en.wikipedia.org/wiki/Network_analyzer_(electrical)

    ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...

  7. Received signal strength indicator - Wikipedia

    en.wikipedia.org/wiki/Received_signal_strength...

    Cellular signal strength of -74dBm (or 66 asu) displayed on a smartphone.Also shown: signal bars of two cellular networks, and signal bars of a Wi-Fi network. In telecommunications, received signal strength indicator or received signal strength indication [1] (RSSI) is a measurement of the power present in a received radio signal.

    It is not an anonymity tool like Tor. [1] Lantern was developed and is maintained by Brave New Software Project, a 501c3 nonprofit organization. Brave New Software was founded in 2010 and “is dedicated to keeping the internet open and decentralized through user-focused open tools that solve practical problems in how the internet works for ...

  9. MTR (software) - Wikipedia

    en.wikipedia.org/wiki/MTR_(software)

    My traceroute, originally named Matt's traceroute (MTR), is a computer program that combines the functions of the traceroute and ping programs in one network diagnostic tool. [ 2 ] MTR probes routers on the route path by limiting the number of hops individual packets may traverse, and listening to responses of their expiry.
