How do you calculate good wireless test capacity?

Multiply output per cycle by available cycles to get gross capacity, then multiply by uptime and first-pass yield. With 4 units/cycle, 480 cycles, 90% uptime and 97% yield you get 4 x 480 x 0.90 x 0.97 = 1,676 good units from a 1,920-unit gross.

Why is my good capacity so much lower than gross?

Two independent losses stack multiplicatively. In the default case, 10% downtime removes 192 units and 97% first-pass yield removes another 51.8 units, dropping 1,920 gross to 1,676 good.

What is a good first-pass yield for RF/wireless terminal testing?

Mature POS radio test lines run 96-99% first-pass. Below ~95% you are usually chasing antenna tuning, connector seating, or shield-box calibration rather than genuine field defects.

How do I raise wireless test capacity without adding chambers?

Attack uptime first (calibration drift, DUT loading time, cable wear) and yield second. Getting uptime from 90% to 95% adds ~93 good units here, often cheaper than a second shielded chamber.

Gross vs good capacity - which do I quote to planning?

Always quote good capacity (1,676) for ship commitments. Gross (1,920) is only useful for theoretical station design and never survives contact with real uptime and yield.

Does this apply to Wi-Fi, BLE and cellular test steps together?

Yes, if they run in one chamber cycle. If radios are tested in separate cells, run the calculator per station and the slowest good-capacity station sets the line rate.

Payment Terminal & Retail Hardware calculator

Wireless Test Capacity Calculator

Wireless test capacity measures how many payment terminals a cellular/Wi-Fi RF test cell can actually verify as good over a shift, after subtracting station downtime and first-pass test failures. RF and BLE/Wi-Fi radio validation is a mandatory gate on POS and mPOS builds, and the shielded test chamber is almost always the tightest station on the line. Test engineers and NPI planners use this number to size chamber count, staff certification runs, and commit to daily ship quantities. Because RF retests are expensive and slow, small changes in first-pass yield swing your good-unit output more than most people expect.

What this calculator does

Estimate wireless test capacity for payment terminal and retail hardware using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
Use it when wireless test capacity in payment terminal and retail hardware is being asked to take on more work and you need to know if there is room.
It computes net good wireless-verified terminals per shift by multiplying cycle output by available cycles, then derating for chamber uptime and radio first-pass yield.

Formula used

Gross wireless test capacity = wireless test capacity output per cycle × available wireless test capacity cycles
Good wireless test capacity = gross capacity × expected wireless test capacity uptime × expected wireless test capacity first-pass yield

Inputs explained

Terminals RF-tested per chamber cycle:
Available RF test chamber cycles per shift:
RF chamber uptime:
Radio test first-pass yield:

How to use the result

Use it when sizing shielded RF test stations, committing daily wireless-tested ship quantities, or quantifying how uptime and yield losses erode a capacity plan.
It assumes uptime and first-pass yield are independent and stable; in reality a marginal antenna design can spike RF failures batch-to-batch, so a single blended yield can hide real variation.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
