With the recent emergence of standards, wireless solutions are ready to be deployed in building automation networks. IEEE 802.15.4 is a standard for short range wireless networks. Its major applications fields are home and building automation, as well as
The use of wireless technologies for medical device communication, health monitoring (at hospitals or homes) and mobile healthcare information delivery (i.e. m-Health) is one of the most rapidly growing areas in health-IT research today. The papers which

This chapter discusses the use of wireless networks in the context of the smart grid. First, it provides an overview of the various applications envisaged in the smart grid and discusses their communication requirements. Sifting through thousands of
[Superseded by SP 800-121 Rev. 2 (May 2017): http://www.nist.gov/manuscript-publication- search.cfm?pub_id=922974] Bluetooth is an open standard for short-range radio frequency communication. Bluetooth technology is used primarily to establish wireless
In order to contain a differential propagation delay in a block based cooperative MIMO system, a guard interval can be inserted to mitigate the effect of inter-symbol interference. A larger block size could substantially increase the effective symbol rate
In this paper, we present a multi-gate mesh network architecture that has been developed to ensure high performance and reliability under emergency conditions when a system expects to receive power outage notifications and exchanges. In order to handle the
Sensor nodes in wireless networks often use batteries as their source of energy, but replacing or recharging exhausted batteries in a deployed network can be difficult and costly. Therefore, prolonging battery life becomes a principal objective in the

We analyze data from NIST field tests in which radio-propagation channel characteristics were measured at approximately the same physical locations where the performance of various RF-based firefighter distress beacons was tested. These side-by-side tests
A wireless local area network (WLAN) is a group of wireless networking devices within a limited geographic area, such as an office building, that exchange data through radio communications. The security of each WLAN is heavily dependent on how well each
Efficient deployment strategies are proposed for a mobile sensor network, where the coverage priority of different points in the field is specified by a prescribed weight function. According to these strategies, each sensor detects coverage holes within
Abstract: This is an Editorial for the December, 2011 issue of IEEE Microwave Magazine. Kate Remley writes about items of interest to the Microwave Theory and Techniques Society (MTT-S).
This paper presents a framework for analysis of the coverage and capacity of advanced metering over a wide area cellular network. The coverage analysis predicts the maximum cell size subject to an outage criterion, and the capacity analysis predicts the

Synthetic aperture measurements of a reverberation chamber's unstirred wireless channel are used to compare the observed power, time-of-arrival, and angle-of-arrival of unstirred multipath components to that predicted by ray/image theory for a rectangular

Frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) was employed to measure over 100 transitions in the R-branch of the b1Σg+←X3Σg-(0,0) band for the rare O2 isotopologues. The use of 17O- and 18O-enriched mixtures allowed for line positions to be
The millimeter and submillimeter frequency ranges are becoming very important to todays electronics, security and communication industries. NIST has undertaken a research program to aggressively pursue this area. This paper will cover the millimeter

The public safety community requires dependable wireless communications in buildings that often disrupt the radio frequency propagation due to the construction material, architectural features, or large physical dimensions. Here we introduce measurements
Emerging technologies for mesh networks can provide users with last-mile service to an access point by forwarding data through wireless relays instead of through expensive wireline infrastructure. While an extensive amount of literature on mesh networks
The linear dispersion structure is employed to accommodate the dynamic topology of cooperative networks, as well as to achieve higher throughput than conventional space-time codes based on orthogonal designs. Asynchronous Cooperative Liner Dispersion Codes
In this treatise, we propose a novel family of Asynchronous Cooperative Linear Dispersion Codes (ACLDCs), which is capable of maintaining full diversity in cooperative scenarios even at the presence of asynchronous reception. The linear dispersion
