nOversight vs PhosphorCalc

Wi-Fi you can understand. nOversight combines signal strength, signal quality and network performance into one clear story: where your Wi-Fi is strong, where it struggles and what's causing it, with real measurements behind every result. Walk around your home or workplace with your iPhone or iPad and your Wi-Fi story builds as you go. It shows how well your Wi-Fi equipment covers each area, how your device roams between access points or mesh devices, and how your internet connection holds up as you move. A walk test shows you where the problem is, which helps you decide whether to move the router, add a mesh device or change a setting. Walk the same route again afterwards and compare the results to see what your changes achieved. You don't need specialist hardware or an account. Built for home users and Wi-Fi professionals: start with the summary, then dig into as much detail as you like. YOUR WI-FI STORY The story checks each part of your connection and works out which ones are causing problems, then sums it up in plain language: • Coverage: where the signal is good enough, and where it isn't • Roaming: when your device moved between access points or mesh devices, and whether it moved at the right time • Wi-Fi speed: the link rates your device and access point actually achieved • Quality: how much noise and interference there is compared with your signal • Internet: built-in Orb tests measure speed and responsiveness, so you can tell a Wi-Fi problem from a broadband one Results are graded against thresholds you can adjust. The defaults suit home use, and you can tighten them to the targets used in business networks. SEE IT WHERE IT HAPPENS • Map View: walk a floor plan or outdoor area and build a live Wi-Fi heatmap • AR View: hold up your device to see Wi-Fi performance laid over the room around you FIND OUT WHAT ALREADY HAPPENED A dropout may be over by the time you start testing. nOversight can read your device's recent connectivity history and turn it into a timeline. It shows which network and access point you were on, when the signal dropped and when your device roamed. FOR INSTALLERS AND IT PROFESSIONALS Every result in the story comes from the underlying measurements, and you can see all of them: • Real RSSI in dBm, noise, SNR and data rates • Channel, bandwidth (estimated), band and Wi-Fi generation, including Wi-Fi 6, 6E and 7 • Access-point detail and a roam-by-roam history • Signal history and histograms • Why your device chose one access point over another With Pro Analyzer you can save recordings and reopen them later. You can also import diagnostic logs to get retry and congestion data for coverage checks, deployment validation and troubleshooting. YOUR WI-FI DATA STAYS ON YOUR DEVICE nOversight analyses your Wi-Fi on your iPhone or iPad. There's no account and no cloud sync, and your recordings are never sent to us. Speed and responsiveness tests connect to test servers only to measure your internet connection. CHOOSE YOUR LEVEL Free: live monitoring in short sessions, so you can see your connection straight away. Analyzer: unlimited monitoring, plus roaming timelines, access-point analysis, signal history and histograms. Pro Analyzer: everything in Analyzer, plus saved recordings and diagnostic log import for retry and congestion detail.

RF and antenna calculator for amateur radio operators. Ten standalone calculators on a clean, fast interface. Numbers in, numbers out. No network, no accounts, no subscriptions. DIPOLE Calculate half-wave dipole, quarter-wave vertical, and full-wave loop antenna lengths for any frequency. Adjustable velocity factor for different wire types. Results in both metres and feet. WAVELENGTH Bidirectional frequency and wavelength conversion. Enter either value and the other is derived instantly. Identifies standard amateur band allocations (ITU Region 1) automatically. PATH LOSS Free space path loss calculator with approximate S-meter reading context. Supports kilometres and miles. Result can be imported directly into the Link Budget calculator. COAX LOSS Feedline attenuation for seven common cable types: RG-58, RG-8X, RG-213, LMR-240, LMR-400, Aircell 7, and Ecoflex 15. Uses log-linear interpolated manufacturer data across frequency. Shows power delivered to antenna from a 100W transmitter. Result can be imported into the ERP calculator. ERP / EIRP Effective radiated power accounting for transmitter output, feedline loss, and antenna gain. Supports both dBi and dBd gain input. Shows feed power, EIRP, and ERP in watts and dBW. SWR Standing wave ratio from forward and reflected power readings, or direct SWR entry. Calculates return loss, mismatch loss, reflection coefficient, and power delivered. Colour-coded SWR indicator: green for good, amber for marginal, red for poor. POWER Ohm's law solver: pick any two of voltage, current, resistance, and power — the other two are calculated. Separate dB conversion section converts between watts, milliwatts, dBm, and dBW. LINK BUDGET Complete end-to-end signal path analysis. Enter TX power, feedline losses, antenna gains, and path loss to see received signal power in dBm and microvolts, S-meter estimate, and link margin above noise floor. Selectable receiver bandwidth: CW, SSB, FM, or Digital. LC RESONANCE LC tank circuit calculator. Solve for resonant frequency, inductance, or capacitance given the other two values. Displays inductive and capacitive reactance at resonance as a cross-check. IMPEDANCE L-network impedance matching calculator. Given source and load impedance at a target frequency, calculates component values for both low-pass and high-pass matching network topologies. Shows Q factor and network orientation. FEATURES All calculations update live as you type Tap any result to copy it to the clipboard Cross-tab import: pull coax loss into ERP, path loss into link budget Every calculator includes built-in reference notes explaining the formulae Clear and reset controls on every tab Decimal keypad input throughout No internet connection required — everything runs locally No tracking, no analytics, no data collection Part of the Phosphor radio suite alongside PhosphorRTTY, PhosphorCW, PhosphorHertz, and PhosphorSol.
