SCALABILITY CONCERNS OF CHIRP SPREAD SPECTRUM FOR LPWAN APPLICATIONS
Divergent modulation schemes have been proposed for the Internet of Things (IoT). Low Power Wide Area
Networks (LPWAN) technologies are gaining unprecedented acceptance in IoT application of sensor
networks. Chirp Spread Spectrum (CSS) is a prominent modulation technique proposed for LPWAN. Chirps
can traverse long distance and are resilient to noise and Doppler effects. Noise resilience along with
transmission range and low power requirement makes CSS a preferred modulation scheme for sensor
networks. LoRaWANTM, with its physical (PHY) layer using CSS, has emerged as the widely accepted
LPWAN solution. By using CSS modulation with orthogonal spreading factors (SF), LoRa offers wide
coverage to LPWAN applications while supporting a high volume of devices. However, scalability
performance of CSS has not been inadequately modeled. As with the suitability of the modulation scheme,
there are concerns on how chirps interact with the surrounding as the number of deployments bursts out
into higher volumes. We evaluate CSS at ISM band 868 MHz for spreading factor 7 to 12 at bandwidth 125
kHz for performance and scalability. Simultaneous transmissions were simulated with repeated iterations
and conclusions are arrived on collisions rate, packet error rate, and bit error. Suitability of using CSS for
sensor networks for future deployments is commended.

transmission range and low power requirement makes CSS a preferred modulation scheme for sensor
networks. LoRaWANTM, with its physical (PHY) layer using CSS, has emerged as the widely accepted
LPWAN solution. By using CSS modulation with orthogonal spreading factors (SF), LoRa offers wide
coverage to LPWAN applications while supporting a high volume of devices. However, scalability
performance of CSS has not been inadequately modeled. As with the suitability of the modulation scheme,
there are concerns on how chirps interact with the surrounding as the number of deployments bursts out
into higher volumes. We evaluate CSS at ISM band 868 MHz for spreading factor 7 to 12 at bandwidth 125
kHz for performance and scalability. Simultaneous transmissions were simulated with repeated iterations
and conclusions are arrived on collisions rate, packet er

Generating Insights
The document compares licensed versus unlicensed spectrum for wireless communication in smart grids. It notes that unlicensed spectrum is free but crowded, limiting signal strength and requiring more infrastructure. Licensed spectrum is scarce but provides exclusive usage rights, allowing stronger signals over longer distances with less infrastructure. The Sensus FlexNet system uses licensed spectrum to create wireless networks for utilities that cover large areas with minimal infrastructure requirements. Going forward, spectrum needs will expand as utilities require more advanced and secure communications networks.
Smarter Grid Demands Flexible Communications - Electric Light & Power
General Electric has collaborated with CenterPoint Energy to advance smart grid technology in Houston. CenterPoint needed a solution to connect over 5,500 meter data collection devices to more than 2.2 million smart meters across its 5,000 square mile service area. CenterPoint chose GE's Digital Energy business and its WiMax network, which included radios and engineering support. The WiMax network allows meter data to be gathered wirelessly and transmitted to CenterPoint's data center for storage and processing. GE's various wireless technologies provide secure and flexible communications needed for utilities to realize the full potential of the smart grid.

Mobile Ad Hoc Network (MANET) is a collection of two or more devices or nodes or terminals with
wireless communications and networking capability that communicate with each other without the aid of
any centralized administrator also the wireless nodes that can dynamically form a network to exchange
information without using any existing fixed network infrastructure. And it’s an autonomous system in
which mobile hosts connected by wireless links are free to be dynamically and some time act as routers at
the same time, and we discuss in this paper the distinct characteristics of traditional wired networks,
including network configuration may change at any time , there is no direction or limit the movement and
so on, and thus needed a new optional path Agreement (Routing Protocol) to identify nodes for these
actions communicate with each other path, An ideal choice way the agreement should not only be able to
find the right path, and the Ad Hoc Network must be able to adapt to changing network of this type at any
time. and we talk in details in this paper all the information of Mobile Ad Hoc Network which include the
History of ad hoc, wireless ad hoc, wireless mobile approaches and types of mobile ad Hoc networks, and
then we present more than 13 types of the routing Ad Hoc Networks protocols have been proposed. In this

Benefits of Electronic Medical Records
Randall Fincke has dedicated over 25 years to enhancing patient care through his company Advent Medical Products, where he creates innovative medical devices and software with engineers and medical professionals. Electronic medical records are being developed to better track patient data and coordinate care between facilities by giving doctors, patients, and families improved access. Compared to traditional records, electronic medical records provide more legible, private, and secure documentation while also increasing medical facilities' efficiency and workflow to deliver better patient care.
Wearable Defibrillators Help Cardiac Patients
Randall Fincke leads a company that designs wearable defibrillators to help cardiac patients. Studies show that wearable defibrillators can provide protection for patients who need arrhythmia monitoring and treatment. Data shows that patients who used wearable defibrillators kept them on for all but three hours per day on average. During that time, about a quarter of patients received effective electrical shocks to treat arrhythmias, while the rest deactivated the shock response intentionally. Wearable defibrillators have saved many lives by providing early intervention and response in cardiac emergencies.
Portable medical device market 20 b.13-7-22
The global portable medical devices market is expected to reach $20 billion by 2018, growing at a double-digit compound annual growth rate. Mobile medical devices that incorporate wireless technologies have improved healthcare by allowing for increased patient mobility and real-time monitoring. Semiconductor components like processors, memory, and connectivity chips contribute over half of the total costs for many portable health devices. The top segments driving market revenues are cardiac monitors and independent aging products, with North America currently the largest market but Asia-Pacific expected to see strong future growth.
Quality versus conformity 13-7-14
The document discusses the lack of a universal definition for "quality" in healthcare. It argues that commonly used quality measures focus more on easy-to-measure guidelines rather than what really matters for patients. The author provides several examples where accurate diagnoses or treatments were delayed due to a focus on following protocols over individual patient needs. The document concludes that quality healthcare requires treating each patient with compassion while balancing their needs with scientific evidence and societal considerations. Defining quality is complex with many intangible factors, so measures need to be patient-centered without losing sight of medical foundations.
Uk surgeries on fridays recovery-13-6-4
1) A study found that patients who undergo surgery on Fridays are almost 50% more likely to die than those having surgery on Mondays, with about 1,600 patients dying needlessly each year due to reduced hospital staffing and services on weekends.
2) The risk of complications and death increases throughout the work week as the post-operative recovery period is more likely to overlap with weekends when senior doctors, nurses, and diagnostic services are reduced.
3) An analysis of over 4 million operations in England found that the mortality rate after Friday surgeries was 44% higher than after Monday surgeries, even after adjusting for patient and procedure factors. Surgeries planned for weekends had an 82%
Affordable care act med page-13-5-30
Under the transparency imperative, more healthcare data and information should be made publicly available, including price, quality, and utilization data, unless there is a compelling reason for privacy. This would help patients choose higher value providers and help providers operate under new payment models. While the ACA made some data available, more can be done, such as opening Medicare claims data and requiring transparency of prices. Greater transparency is needed for the healthcare system to achieve better quality and cost control.
Forbes 5 biggest healthcare challenges-13
Early elective deliveries between 37 and 39 weeks gestation exemplify the five biggest problems in the US healthcare system: (1) too much unnecessary care, (2) avoidable harm to patients, (3) billions wasted on unnecessary care, (4) perverse incentives in how care is paid for, and (5) lack of transparency. Public reporting of early elective delivery rates by hospitals has helped reduce the national rate from 17% to 11.2% since 2010 by galvanizing changes, showing the power of transparency. While progress has been made on this issue, continued pressure is needed to encourage real change and apply this model across other areas to address the systemic problems.

New Wireless Standards Promise Better Communication for EMS Personnel
- 2. An experienced medical device developer and executive, Randall Fincke serves as chief executive officer of Advent Medical Products. In this capacity, Randall Fincke oversees a number of projects, including devices for use by emergency medical services (EMS) personnel. EMS personnel in the field often face challenges communicating with hospitals and with one another In disaster situations. However, thanks to the allocation of the D-Block 700 MHz spectrum and the creation of FirstNet, a governing body, responders will soon gain the ability to leverage LTE (also known as 4G) via the nationwide public safety broadband network (NPSBN) for communications purposes using devices such as tablets and data applications.
- 3. The NPSBN, which operates for public safety use, will provide responders with communications channels that will not experience network overload. Thanks to developments by industry players, LTE networks and existing LMR networks will have interoperability for maximum flexibility. Rolling out the NPSBN in a manner that allows for communication between responders will require multiband radios capable of running on the many frequencies used by emergency personnel. Such devices will allow for better collaboration during disaster situations.
