For macro–femto network, intratier and cross-tier interference (CI) must be canceled to achieve the quality of service, better indoor coverage, and higher data rates. Moreover, for better wireless local area network (WLAN) and mobile communication services while ensuring WLAN security, appropriate temperature in modern buildings with reduced energy cost is also required. To address these issues, RadioClear (RC) film can be pasted on an ordinary glass and installed in different sections to cancel the intratier interference between the femto network as well as CI between the femto and macro network. Moreover, this technique can also ensure enhanced WLAN security and thermal insulation in modern buildings. For WLAN transmission, a fractal dual bandpass frequency selective surface (FSS) designed in the RC sheet can be used to improve the WLAN communication in a situation where two or more than two rooms are served through a single WLAN router. Theoretical results are presented which are further verified through the experimental results.

使用 FSS 和 RC 薄膜改善 WLAN 传输和建筑物隔热的移动电话信号干扰消除

对于宏毫微微网络，必须取消层内和跨层干扰 (CI) 以实现服务质量、更好的室内覆盖和更高的数据速率。此外，为了在保证WLAN安全的同时获得更好的无线局域网（WLAN）和移动通信服务，现代建筑中还需要适当的温度，同时降低能源成本。针对这些问题，可以将RadioClear (RC) 膜贴在普通玻璃上，并安装在不同的部分，以消除毫微微网络之间的层内干扰以及毫微微和宏网络之间的CI。此外，该技术还可以确保现代建筑中增强的 WLAN 安全性和隔热性。对于 WLAN 传输，在 RC 表中设计的分形双带通频率选择表面 (FSS) 可用于在通过单个 WLAN 路由器为两个或两个以上房间提供服务的情况下改善 WLAN 通信。给出了理论结果，并通过实验结果进一步验证。
