A new LTE protocol named LTE Direct is a device-to-device technology enabling the discovery of thousands of devices in the proximity of approximately 500 meters.  Pioneered by Qualcomm , the company has been leading the standardization of this new technology along with other 3GPP participants. LTE Direct offers several advantages over existing proximity solutions including but not limited to Wi-Fi or Bluetooth . One of the most popular use cases for this technology was developed by a New York City based company called Compass. The core feature of proximal discovery among devices included a targeted discount voucher to a nearby device which matched specific interests.  The Compass use case was featured at global conferences and events such as CES 2015, MWC 2015, and said to be extended to many other scenarios including film festivals, theme parks and sporting events. It is claimed [ by whom? ] that the protocol offers less battery drainage and extended range when compared to other proximity solutions.
The syndromes included here represent a variety of clinically relevant infections that can occur in the LTCF population. Surveillance should be performed for infections for which there are clear strategies that can be implemented for prevention and control of transmission ( Table 1 ). However, for completeness and consistency with the original surveillance definitions, 1 several infections that may occur because of underlying host factors rather than transmission within the facility have also been included in this document, so that both infection prevention programs and research studies have a standard set of criteria. Given the limited infection prevention and control resources that are currently available in most LTCFs, surveillance activities may need to target those infections in a facility that have the most potential for prevention. In addition, some infections are associated with a high likelihood of transmission and development of outbreaks (eg, norovirus, influenza, group A Streptococcus , acute viral hepatitis). For these infections, identification of even a single case in a LTCF should trigger a more intensive investigation. 6 , 7
