As wearable devices become more ingrained in our daily lives, traditional communication networks primarily designed for human being-oriented applications are facing tremendous challenges. The upcoming 5G wireless system aims to support unprecedented high capacity, low latency, and massive connectivity. In this article, we evaluate key challenges in wearable communications. A cloud/edge communication architecture that integrates the cloud radio access network, software defined network, device to device communications, and cloud/edge technologies is presented. Computation offloading enabled by this multi-layer communications architecture can offload computation-excessive and latency-stringent applications to nearby devices through device to device communications or to nearby edge nodes through cellular or other wireless technologies. Critical issues faced by wearable communications such as short battery life, limited computing capability, and stringent latency can be greatly alleviated by this cloud/edge architecture. Together with the presented architecture, current transmission and networking technologies, including non-orthogonal multiple access, mobile edge computing, and energy harvesting, can greatly enhance the performance of wearable communication in terms of spectral efficiency, energy efficiency, latency, and connectivity.

This communication presents a compact dual element wearable ultrawideband (UWB) multi-in multi-out (MIMO) antenna with increased port isolation. The suggested design consists of a jeans substrate in which a tree fashioned stub comprising of 8(eight) branches is introduced in the middle position of the partially etched antenna ground for improving the characteristics of port isolation. The proposed design occupies the frequency spectrum operating from 1.71 to 12.63GHz (impedance bandwidth of around 152.3 percent) and satisfies the bandwidth demands for WiMAX (3.2-3.8 GHz), WLAN (5.15-5.35/5.72-4.85 GHz), the C Downlink-uplink bands (3.7-4.2/5.9-6.425GHz), ITU bands (8-8.5GHz) and the downlink defense band (7.2-7.5GHz). The antenna is able to maintain isolation between the ports of > 22dB across the entire UWB frequency spectrum. The coefficient of the envelope correlation for the whole operating band was observed to be < 0.012 along with a very high diversity gain > 9.9. The channel power loss of the proposed wearable UWB MIMO antenna is found to be < 0.27 bit/s/Hz. The suggested UWB MIMO antenna, fascinated with optimization, covers an area of 35 x 35 mm 2. The suggested design is also able to perform satisfactorily when attached on-body. Simulation and testing fairly identified the performance of the antenna and rendered it to be an upstanding choice for wearable UWB applications.

“…A dual-band dual-mode antenna 13 using shorting pins and arc-shaped slots suitable for body-centric communication is illustrated but it results in the narrow bandwidth. Thus from the aforementioned literature, it is evident that the wearable antenna is designed with large antenna dimension and high profile operating only for off body mode, [4][5][6] dual application bands operating for each mode, respectively [5][6][7][8]11,14,15 and single resonance antenna operates in both modes of communication simultaneously. 9,[16][17][18] To overcome this, wearable antenna requires the following characteristics: (1) compact antenna with low profile (2) antenna with multiple application bands (3) it is likely to have a multiband antenna that could operate in both on and off body modes.…”

A low profile, a multifrequency microstrip patch antenna with pattern reconfiguration is reported in this paper. The proposed antenna provides both omnidirectional and directional radiation characteristics suitable for Wireless Body Area Network (WBAN). Pattern switching is achieved using PIN diodes. The antenna is designed to operate at multiple frequencies, viz. 0.915 GHz (Industrial Scientific & Medical band), 2.38 GHz (Medical body area network), 3.5 GHz (Wireless Interoperability for Microwave Access), and 5.8 GHz (Wireless Local Area Network/Industrial Scientific & Medical band). The percentage bandwidths obtained are 2.89, 1.68, 2.85, 2.16 at the operating frequencies 0.915, 2.38, 3.5, 5.8 GHz, respectively. The peak gain and total efficiencies obtained for OFF mode are 3.22/4.27/4.65/4.82 dBi, 82/85/87/89%, and in ON mode are 1.12/1.80/2.44/2.68 dBi, 65/67/71/74% at the said operating bands, respectively. The path loss model is evaluated by measuring the transmission link between the antennas on the human body. The LOS path ranges from 30 to 45 dB and the NLOS ranges from 50 to 80 dB ensuring it satisfactory for WBAN application. Then human body loading characteristics are also studied. The SAR analysis is performed and it is found to be less than 1.6 W/Kg.
