“…This was however not done here: due to the proximity of the metallic container surface, antenna effects cannot be separated from the wireless propagation loss. This is highly similar to the definition of path loss for on-body propagation channels, where the proximity of the human body also prevents exclusion of antenna radiation patterns from the wireless propagation loss [7].…”

Abstract-This paper presents empirical path loss models for an environment of stacked shipping containers. Specifically, a system for wireless monitoring of containers is considered for which three different types of wireless links are identified, namely intra-, inter-, and extra-container links. Furthermore, the intercontainer link is investigated for the two most common types of container stacking: row and block stacking. Intra-and intercontainer path loss is investigated at IEEE 802.15.4 frequencies of 433, 868, and 2400 MHz. Extra-container path loss is examined at GSM/UMTS frequencies of 900, 1850, and 2100 MHz. Distancedependent path loss models are proposed for the inter-and extracontainer links (high correlation coefficients between 0.76 and 0.86). The resulting path loss models can be used in link budget calculations for container monitoring systems.

“…If a sensor does not receive an acknowledgement, it performs a bounded number of retransmissions. 5 If all retransmissions are exhausted without receiving an acknowledgement, the packet is counted as a failure, otherwise as a success. Sensor devices attempt to receive all beacons from their coordinator to stay synchronized.…”

We consider scenarios where a large number of wireless body sensor networks (WBSN) meets at the same location, as can happen for example at sports events, and assess the impact of their mutual interference on their achievable transmission reliability. In particular, we consider several of MAC-and application parameters for a range of static and dynamic schemes for allocating WBSNs to frequencies, and determine their relative impacts on achievable performance. Our results indicate that parameters related to the MAC backoff scheme have by far the largest impact on performance, and that frequency adaptation can provide substantial performance benefits.

“…The research of wearable computing systems has experienced rapid development over the past decade due to their great potential applications such as health monitoring, wireless communication and other intelligent terminals [1][2][3]. As one of the key components in the communication system, wearable antennas have received much attention in both academia and industry since their unconventional operating environment is in extremely close proximity to the human body [4].…”

Abstract-This paper presents a compact, low-profile, wearable dual-band antenna operating in the Wireless WLAN band of 5.15 ∼ 5.25 GHz and 5.72 ∼ 5.83 GHz. The proposed antenna is composed of a planar monopole and underneath three by three array arrangement of Jerusalem Cross (JC) structure metasurface. The simulated results show that the integrated antenna express 4.09% and 4.14% impendence bandwidths, increased gain up to 7.9 dB and 8.2 dB, front to back (FB) ratio achieved to 20 dB and 18 dB at the two frequencies, respectively. The measured results agree well with simulations. In addition, the metasurface not only is equivalent to a ground plane for isolation, but also acts as the main radiator, which enables a great reduction in the specific absorption rate (SAR). Furthermore, because of a compact solution, the proposed integrated antenna can be a promising device for various wearable systems.
