Wireless Calculators

27 free wireless calculators in Networking.

2.4 GHz Channel PlannerPlan a 2.4 GHz deployment against the only three non-overlapping channels, and see the co-channel contention it creates.
5 GHz Channel PlannerCount the non-overlapping 5 GHz channels available at your chosen width with or without DFS, and check the reuse it allows.
6 GHz Wi-Fi PlannerPlan 6 GHz Wi-Fi 6E/7: channel count for your regulatory domain, LPI or standard-power EIRP and the resulting cell radius.
Access Point Density CalculatorSize an access point count from both coverage area and client capacity, and see which of the two actually drives the design.
Access Point PlanningCalculate the number of access points needed to cover an area with target capacity.
Beamforming Gain CalculatorWork out array gain, total antenna gain, directivity from beamwidth and the range multiplier a phased array delivers.
Channel Width CalculatorTrade Wi-Fi channel width against PHY rate, noise-floor penalty and how many non-overlapping channels remain for reuse.
Client Density CalculatorCheck clients per radio and per access point against your design target, and see how much spare association capacity is left.
Coverage Heatmap EstimatorEstimate indoor cell radius, cell area and AP count from EIRP, target RSSI, wall losses and a path-loss exponent.
Frequency ConverterConvert radio frequencies between Hz, kHz, MHz and GHz and calculate wavelength.
Fresnel ZoneCalculate the Fresnel zone radius and clearance needed for a line-of-sight wireless link.
Mesh Wi-Fi CalculatorEstimate throughput at the edge of a wireless mesh after per-hop backhaul loss, for shared-radio and dedicated-backhaul designs.
MU-MIMO Capacity CalculatorSize the multi-user MIMO gain from AP and client spatial streams, including group size, sounding overhead and stream utilisation.
OFDMA Efficiency CalculatorCompare 802.11ax OFDMA against single-user transmissions: resource units per channel, users per TXOP and the airtime saved.
Point-to-Multipoint PlannerPlan a sectorised point-to-multipoint site: subscribers per sector, offered load, azimuth coverage and the subscriber ceiling.
Point-to-Point Link CalculatorClose a point-to-point wireless link: free-space path loss, received signal level, EIRP and the fade margin left over.
Roaming Capacity CalculatorWork out roam events per second, concurrent roams and RADIUS authentication load, with and without 802.11r fast transition.
RSSI CalculatorConvert between RSSI dBm values and signal quality percentage for wireless links.
Signal StrengthCalculate received wireless signal strength from transmit power, distance and path loss.
SNR CalculatorCalculate the signal-to-noise ratio from signal and noise power levels.
WiFi CapacityCalculate the number of concurrent devices a WiFi network can support at target throughput.
WiFi Channel CalculatorFind non-overlapping WiFi channels and center frequencies for 2.4GHz and 5GHz bands.
WiFi CoverageEstimate WiFi access point coverage radius and area based on power and environment.
Wireless Health Score CalculatorScore a Wi-Fi estate across coverage, SNR, channel utilisation, retries, roaming and headroom, and find the weakest dimension.
Wireless Interference CalculatorTurn signal, co-channel, adjacent-channel and noise-floor levels into SNR, SINR and the modulation the link can actually hold.
Wireless Link BudgetCalculate the complete link budget for a wireless link including gains and losses.
Wireless Throughput CalculatorModel real Wi-Fi cell throughput with airtime fairness, so slow legacy clients drag the whole cell down the way they do in practice.
