Hi  @Dharam_is_in 

Thank you for your question regarding the EAP773 antenna power differences between the US and Singapore versions. We appreciate your interest in optimizing your indoor setup.

Regarding the increased antenna power in the US version, it’s important to note that while higher power can theoretically provide stronger signal coverage, it may not always translate to better performance in your specific environment.

Here are a few key considerations:

1. **Regulatory Compliance**: The US version is designed to comply with FCC regulations, which allow for higher transmit power. However, using a device with higher power in Singapore may not comply with local regulations (IMDA), potentially leading to legal or interference issues.

2. **Interference and Overlap**: In densely populated areas like Singapore, higher power can increase the risk of signal interference with neighboring networks, especially in indoor environments with multiple access points. This could degrade overall performance rather than improve it.

3. **Environmental Factors**: Indoor setups often have obstacles like walls, furniture, and other devices that can impact signal quality. In such cases, proper placement and configuration of the access point may be more beneficial than simply increasing power.

4. **Warranty and Support**: As you mentioned, using the US version in Singapore may void the warranty and limit access to region-specific support and firmware updates, which could affect long-term reliability.

In summary, while the US version may offer higher antenna power, it may not necessarily provide a better benefit for your indoor setup in Singapore. We recommend using the Singapore version to ensure compliance with local regulations and optimal performance in your environment. If you’re experiencing coverage issues, we’d be happy to assist with placement and configuration tips to maximize your network’s performance.
