The reliability of the Huawei Watch Ultimate's satellite SMS feature in areas with heavy tree cover can be influenced by several factors, including the type of satellite system used and the specific conditions of the environment. Here's a detailed analysis:
Satellite System Used
The Huawei Watch Ultimate uses the Beidou satellite system for its satellite SMS feature. Beidou is a Chinese satellite navigation system that also supports communication services. While Beidou satellites are geosynchronous, which can provide stable coverage, the effectiveness in dense tree cover might vary compared to other satellite systems like those using low Earth orbit (LEO) satellites.Performance in Dense Tree Cover
Satellite signals can be affected by dense tree cover due to interference from foliage, which can block or weaken the signal. However, some satellite devices have shown surprising resilience in such conditions. For instance, tests with geostationary satellites in dense forests have demonstrated successful communication, albeit with potential delays or reduced reliability[2]. The SPOT Satellite Messenger, which uses the Globalstar constellation, has also shown some success in sending messages under heavy canopy, though with varying success rates depending on the type of message[5].Huawei Watch Ultimate Specifics
The Huawei Watch Ultimate is designed with a robust build and features a "Beidou Key" for quick activation of satellite communication. It uses miniaturized RF modules and a suspended antenna design to enhance signal transmission[7]. However, there is no specific data available on how well the Watch Ultimate performs in dense tree cover. Given its design for outdoor use and emergency communication, it is likely intended to function in challenging environments, but actual performance may depend on the specific conditions.Conclusion
While the Huawei Watch Ultimate's satellite SMS feature is designed for emergency communication and uses advanced technology to enhance signal transmission, its reliability in areas with heavy tree cover may vary. Users should expect some potential interference or reduced signal strength due to foliage, but the watch's design and technology suggest it could still provide useful communication capabilities in such environments. For critical situations, it's advisable to seek a clear view of the sky if possible to ensure optimal signal strength.Citations:
