Table 7: Potential candidates and their characteristics. between computational capability and physical size that is advantageous for furniture integration. In [29], the authors' work on portable computing solutions utilized a similar form factor (3.5 by 5 inch) that proved effective for space-constrained applications. The standardized mounting holes facilitate installation across various furniture designs while providing sufficient space for essential components without compromising furniture aesthetics or structural integrity and allowing for future upgrades or module replacements, while maintaining the form factor for backward compatibility. The described device is capable of serving as the edge device for multipurpose communication systems, such as the following:  
* Bluetooth HMI devices (similar to Bluetooth speakers);
* Bluetooth concentrators/servers (concentrators for smart home devices that connect through a Bluetooth protocol, like smart bulbs, refrigerators, or similar devices);
* ZigBee concentrators/servers (concentrators for other smart home devices that utilize a ZigBee protocol, such as smart (door, window, water leakage, gas detection, movement) sensors or different smart wearable devices that are a part of Internet of People concepts);
* Wi-Fi concentrators/servers/clients/hot spots/hubs (as concentration points for home surveillance cameras, other security devices, or devices connected using Wi-Fi protocols, like home robots and similar products);
* WWAN communication modules for independent connectivity to the Internet, regardless of the local infrastructure. Such devices can be interconnected throughout the home-making mash capable network for redundant connectivity.
