The Xiaomi 15T series debuted several innovative advances over its predecessor. Let me share my experience on one of the most essential and innovative breakthroughs in mobile connectivity being the first to be unveiled amongst the Xiaomi smartphone globally.
Beyond imaging, Xiaomi 15T Series introduces a leap in mobile connectivity, redefining how users stay connected in various environments. At the heart of this innovation is Xiaomi Astral Communication, a suite of advanced technologies, including the global debut of Xiaomi Offline Communication with Xiaomi 15T Series.
This enables direct voice communication between Xiaomi 15T Series devices over distances of up to 1.9km for Xiaomi 15T Pro, and 1.3km for Xiaomi 15T, even without cellular or Wi-Fi signals. It is ideally suited for open environments such as jungles, deserts, or remote hiking trails, adding an essential extra layer of reliability when traditional networks are unavailable.
For stable and adaptive connectivity across various conditions, Xiaomi Astral Communication also includes Xiaomi Surge T1S Tuner, which flexibly utilizes GPS, Wi-Fi, Bluetooth, and cellular signals.
How to start using:
- Update your Xiaomi 15T Pro to the latest update: Xiaomi HyperOS 2.2 2.0.205.0.VOSMIXM rolled out for Xiaomi 15T Pro
- Update your Xiaomi 15T to the latest update: Xiaomi HyperOS 2.0.206.0.VOEMIXM rolled out for Xiaomi 15T
- Xiaomi Offline Communication requires a SIM card, a Xiaomi account login, and Bluetooth enabled.
- Xiaomi Offline Communication supports voice calls up to 1.3 km for Xiaomi 15T and 1.9 km for Xiaomi 15T Pro away in an open, interference-free environment. Actual call quality may vary depending on environmental conditions.
Offline Communication Experience
Adopting an outdoor lifestyle, going camping or jungle tracking tends to land myself off-the-grid. For the thrill, I went to the extent of actually testing the Offline Communication thingy and frankly it's amazing and it works flawlessly with satisfying results. My test constant was a paddy field without any building obstruction, just bushes and secondary growth. Yes, it holds up to Xiaomi’s claims and it comes essentially useful. Personally it makes the walkie-talkie obsolete.
