TL;DR: In this article, a fair comparison between direct sequence code division multiple access (DS-CDMA) and orthogonal frequency division multiplexing (OFDM) systems for broadband downstream power-line communications (PLCs) is provided.

TL;DR: The main features of a wireless network that aims to interconnect several heterogeneous systems and provide multimedia access to groups of people to better monitor a specific area to have a fast response in case of a disaster, and to efficiently coordinate all of the forces during the disaster management phase are discussed.

TL;DR: A cognitive radio approach based on a noncooperative spectrum-sensing technique that is suitable for applications in detection and avoidance (DAA) schemes to allow coexistence between ultrawideband multiband and Worldwide Interoperability for Microwave Access (WiMAX; primary user) systems and, hence, improve spectral efficiency.

TL;DR: In this paper, a short authentication method for authenticating a supplicant in a wireless communications network is proposed. But the method requires the authentication server to verify the authenticity of the authentication token before sending it to the authenticator.

TL;DR: Different small cell deployment approaches are presented: sharing the same frequency bands with the macrocell, or using separated higher frequency bands: for each approach, the benefits of beamforming are discussed.
