TruSignal Antenna Boost Technology

Qualcomm RF360, Qualcomm TruSignal, and Qualcomm Snapdragon are products of Qualcomm Technologies, Inc.

Give your connectivity a boost.

Using Qualcomm® TruSignal™ antenna boost technology, Qualcomm® Snapdragon™ LTE modems can enhance radio performance for superior mobile experiences. That means improved network reliability, data speeds and call coverage-all delivered with astonishing power efficiency. TruSignal antenna boost owes its outstanding performance to the Qualcomm® RF360™ dynamic antenna matching tuner that powers it.

TruSignal features

Designed to optimize signal strength at all times, TruSignal features mean fewer dropped calls, more bars, and long battery life.

TruSignal antenna boost

The advanced closed-loop impedance tuner is designed to dynamically optimize signal strength in varying user scenarios.

  • Up to 4 dB recovery in transmit power
  • Allows low-band designs (600 MHz)
  • Superior paging/standby coverage

TruSignal multi-antenna boost

The underlying antenna switch diversity technology is designed to allow the modem to smartly and actively select the optimal antenna in multi-antenna architectures.

  • Suitable for extreme death grip
  • Up to 10 dB recovery in transmit power

TruSignal receive boost

Designed to improve signal reception by taking advantage of high-order diversity with more than two antennas.

  • Up to 2.5 dB VoLTE link budget recovery
  • Up to 60% additional throughput compared to 2x diversity
  • Suitable for high bands

TruSignal with carrier aggregation

The third generation Qualcomm TruSignal solution (QAT35xx) is designed to turn the carrier aggregation challenge into an opportunity to squeeze higher signal performance in a device to deliver a more consistent data and voice experience to the end user.

QAT35xx is designed to adaptively optimize both transmit and receive paths by adjusting to impediments, channel fading and hand grips while supporting more than one carrier, so high signal strength can be achieved in various user scenarios and network conditions..
