Kebul na di tin dɛn we de kɛr infɔmeshɔn ɛn pawa we pɔsin kin gɛt. Wan kebul we dɛn nɔ tɛst min se yu nɔ no if i de wok, aw fa i kin go, if brek de na di midul, ɔ if signal attenuation de insay akseptabl limit. Insay kebul injinɛri, kebul tɛst nɔto ‘ɛkstra stɛp’ — na di las layn fɔ difens fɔ dilivri kwaliti.
Wan mistek we pipul dɛn kin tink na dat, dɛn kin tɛst nyu kebul dɛn na faktri ɛn dɛn nɔ nid fɔ tɛst dɛn mɔ.

Bɔt kɔntinyuiti tɛst tu izi fɔ dismis — bɔku pipul dɛn kin tink se ‘as lɔng as i de kɔndɔkt, i fayn.’ In rialiti, kɔntinyuiti tɛst na jɔs di fɔs layt fɔ chɛk. Wan kebul we de kɔndɔkt kin stil nɔ ebul fɔ transmit data di rit we dɛn dɔn mek.
