To quote the FCC: “Consumer Signal Boosters are designed to be used “out of the box” by individuals to improve their wireless coverage within a limited area such as a home, car, boat, or recreational vehicle.” Signal boosters in general are devices that require amplification and/or electronic components to expand the signal coverage.

These elements require FCC approval to prevent interference to wireless networks and to ensure a minimum level of consumer safety, i.e. SAR. These solutions however do not address the other aspects of signal improvement which includes the critical element of polarization diversity. Furthermore, signal boosters can create unwanted noise which disrupts and corrupts wireless signals within the vicinity.

The NxWave case is designed around revolutionary antenna technology that uses inductive coupling (a form of electromagnetic induction, e.g. wireless inductive charging) to provide wireless relief to the many radios in your wireless device. Since the NxWave case is essentially a plug and play passive super antenna, it provides clean and larger coverage patterns. To learn more about why your device needs wireless relief, please see this article from Electronic Design, What Drains The Smartphone Battery?

Yes, as it does not require amplification nor have any electronic components for frequency adjustment or beam steering which is what the FCC would classify as an active antenna solution.

The NxWave case does not require FCC approval because it is not an active component (as described in question 2) so would not increase SAR, which is why it has not been tested for it. Considering that existing competitors only improve selected cellular frequencies, the NxWave case provides the greatest amount of wireless relief as it reduces the workload of all cellular and WiFi (and Bluetooth) radios within the device.

Yes. The NxWave case improves the signal coverage areas of all cellular and WiFi frequencies available within the device. Furthermore, it is the only known case solution to offer polarization diversity, a critical element for improving mobile connectivity.

  • There are two known competitors in the marketplace. The Reach case by Antenna79, which uses the antenna slider solution. It is more expensive, has a larger form factor (because it works when the antenna is extended out; what happens when it’s not?), targets selected cellular frequencies and is a rigid case so offers minimum drop protection.
  • The second solution is mJoose, an active antenna case solution. It is roughly twice the cost, has a larger from factor because of the battery, targets selected cellular frequencies, and is heavier while failing to offer sufficient drop protection because of the active and battery elements. What mJoose does well is provide educational messaging as good as or is better than the Reach case.
  • The NxWave is the only case solution that gives your phone bigger ears without adding extra noise which can interfere with data transmission and reception. It’s redundant signal protection that reduces degradation which can occur from noise, environmental barriers and mobility. By optimizing your signal, the NxWave case improves your device’s connectivity, speed and battery life. The NxWave case is the only real world solution because it offers true global cellular and WiFi (and Bluetooth) coverage and addresses cellular polarization diversity. This is why the iPhone has two antennas for polarization switching
