We needed something to handle the exam hall interference we've been getting — students using WiFi-based relay apps to cheat in real-time, and the 1.5W output on this JYT-160B covers that range of 1-5 meters pretty well, though it does depend on wall thickness and whether they're behind concrete.
It covers GSM, CDMA, DCS, 3G, 4G, and WiFi bands so we don't have to juggle multiple units for different carrier frequencies, and the built-in antenna means no external antennas to trip over or lose.
Battery life is 80 minutes on a full charge, which is enough for a 60-minute exam block plus setup time, but the 2.5-hour recharge cycle means you'll want the AC adapter handy if you're running back-to-back sessions (usually we plug it in during breaks).
The thing weighs only 80 grams and is 110 x 62 x 18 mm, so it fits in a jacket pocket or a small drawer — no one notices it sitting on a podium or shelf, and high-grade plastic case doesn't scratch easily.
It's not meant for large open spaces or outdoor areas — teh range drops off fast past 5 meters, and in a big lecture hall you'd need multiple units, but for a standard 20-person meeting room or a small exam room it's basically perfect.
Operating temp is -10°C to 50°C and storage down to -20°C, so it handles being left in a car trunk in winter or summer without issues, and the 1050mAh battery at 3.7V is a standerd cell so replacement isn't a headache.
It jams all common WiFi bands in its coverage range, so you should expect disruption within 1–5 meters depending on walls and signal strength. If you need to leave some frequencies open, this model doesn’t support selective blocking—it’s all or nothing.
Our standard MOQ is 10 units for the JYT-160B. If you need fewer, let us know—we sometimes accommodate sample orders for first-time buyers.
Lead time is usually 7–10 business days for orders of 10–50 units. Larger batches may take 15–20 days, depending on current production volume.
Yes, we can provide a Certificate of Conformance (CoC) upon request. We also include test reports for output power and battery performance if you need them for customs or internal review.
The 1050mAh battery is built in and not designed for user replacement. If it fails—typically after 300–500 cycles—you’d need to return the unit or order a replacement from us.
