This paper validates the progression and expected trends of integrated wireless and mobile communication technologies. Currently, these breakthroughs have allowed for high quality end-user experience with an acceptable level of usage and efficiency in business organizations. Forthcoming mobile broadband life creates new norms and expectations for end-users from the next business generation, who can utilize integrated wireless and mobile communication technologies in their full potential. Several scenarios from different domains illustrate the power of integrated wireless and mobile communication technologies and their impact on the corporate world. The models and scenarios show that the power of integrated wireless and mobile communication technologies is certainly in several orders of magnitude greater than the simple sum of their separate individual impacts.

Insight Into

In the context of the increased use of high-quality camera phones, along with the growth in distribution services via social and locative media, we are witnessing new forms of visuality emerging. These new types of ‘co-present’ visuality overlay and interweave online and offline cartographies in different ways – maps that require a revision of ethnography. In this article, we frame this phenomenon as a shift from networked visuality to emplaced visuality and sociality. That is, we reflect upon previous models deployed in mobile communication and depart from them to consider how a phenomenological approach – rooted in visual and multisensorial ethnography – might help provide insight into this dynamic media cartography and the socialities associated with it.

A frequency reconfigurable planar monopole antenna for fifth-generation (5G) mobile communication terminal equipment is presented. The proposed antenna uses a meandered monopole, branch resonance and other techniques to make the antenna resonant in multiple frequency bands. The antenna is compact in size (115 mm × 55 mm × 0.8 mm) and has a longitudinal length less than one-tenth of the resonant wavelength (working at 1.79 GHz). The pin diode is designed between the planar meandered monopole antenna and branch. The current path of the high-frequency current on the antenna can be easily controlled by controlling the DC bias voltage of the diode, and the operating frequency of the antenna is switched between three frequency bands. The antenna is fed directly through a 50 Ω matched transmission line. The measured data of the antenna in the anechoic chamber show good consistency with simulation data. The radiation pattern of the antenna shows good omnidirectional characteristics and good frequency characteristics, with a maximum radiation gain of 13.6 dBi. Experimental results demonstrate that the antenna can meet the design requirements of 5G communication.
