WiFi :  Wifi was originally licensed bu the Wi-Fi alliance and it is used to describe the technology of wireless local area networks, abbreviated as WLAN. This technology was primarily developed for mobile computing devices like laptops in Local Area Networks, but with technological advancements, it is now used for an array of services which include VoIP phone access, gaming as well as basic connection of electronics such as smartphones, DVD players, Home theaters and Televisions.
In August 2017, hospitals across the country were penalized with Medicare reimbursement cuts due to high 30-day readmission rates. The potential to reduce these rates and avoid penalties has made telehealth a financial priority. Healthcare provider TripleCare was the subject of a study conducted by the TRECS Institute, which found that virtual physician services had both increased care quality and averted 91 unnecessary admissions. The result was $1.3 million in Medicare savings. Telehealth services can also provide patients and healthcare facilities in rural areas with additional benefits. NTCA — The Rural Broadband Association released a report in March 2017 that estimated the average annual cost savings per facility could add up to:

The term telehealth includes a broad range of technologies and services to provide patient care and improve the healthcare delivery system as a whole. Telehealth is different from telemedicine because it refers to a broader scope of remote healthcare services than telemedicine. While telemedicine refers specifically to remote clinical services, telehealth can refer to remote non-clinical services, such as provider training, administrative meetings, and continuing medical education, in addition to clinical services. According to the World Health Organization, telehealth includes, “Surveillance, health promotion and public health functions.”
While this definition sounds a lot like telemedicine, there is one distinct difference. Unlike telemedicine, telehealth also covers non-clinical events like administrative meetings, continuing medical education (CME), and physician training. Telehealth is not a specific service, but a collection of methods to improve patient care and education delivery.
Universal Service Administrative Company: Abbreviated as USAC, the Universal Service Administrative Company is responsible for administering USFs or Universal Service Funds to allow easy access to telecommunication services across the country. The Rural Health Care Division which is under USAC as well manages discount programs for telecommunications health care.

But getting doctors to jump on board is easier said than done, and takes time. Many are afraid of liability, as it's possible to miss something during a remote visit. And for years, it wasn't clear whether they would get paid as much as an in-person visit. Reimbursement questions are still getting resolved across different states, but most of the commercial and government plans are on board with the idea of telemedicine -- at least in specific circumstances.

“Another distinction between telemedicine and D2C telehealth is that telemedicine consultations are often with medical specialists like cardiologists, dermatologists and pulmonologists,” Downey continued. “These often occur when the patient is in an underserved rural community and the specialist is in a large urban area. The distance makes it difficult to make and keep appointments otherwise. D2C telehealth, on the other hand, best deals with minor primary care issues over the phone. If deemed to be a more serious health concern, the patient is told to make an appointment with a specialist or to proceed to a hospital emergency room.”
Telemedicine was originally created as a way to treat patients who were located in remote places, far away from local health facilities or in areas of with shortages of medical professionals. While telemedicine is still used today to address these problems, it’s increasingly becoming a tool for convenient medical care. Today’s connected patient wants to waste less time in the waiting room at the doctor, and get immediate care for minor but urgent conditions when they need it.
Remote Patient Monitoring involves the reporting, collection, transmission, and evaluation of patient health data through electronic devices such as wearables, mobile devices, smartphone apps, and internet-enabled computers. RPM technologies remind patients to weigh themselves and transmit the measurements to their physicians. Wearables and other electronic monitoring devices are being used to collect and transfer vital sign data including blood pressures, cardiac stats, oxygen levels, and respiratory rates.

Synchronous, real-time or Clinical Video Telehealth requires the presence of both parties at the same time and a communication link between them that allows a real-time interaction to take place. Video-conferencing equipment is one of the most common forms of technologies used in synchronous telehealth. There are also peripheral devices that can be attached to computers or the video-conferencing equipment which can aid in an interactive examination.
Teladoc Health enjoys a killer advantage with its head start in telehealth. Around 40% of the largest companies in the world contract with Teladoc to provide virtual healthcare services to their employees. Over 35 of the biggest health plans in the U.S. have partnered with Teladoc. More than 290 hospitals and health systems have teamed up with the telehealth leader.

Doctor on Demand is a telemedicine service that gives you access to medical doctors 24/7/365 for the treatment of common and worrisome ailments such as urinary tract infections, skin and eye issues, and minor sports injuries. These problems can sometimes lead to trips to the emergency room simply because you cannot get to your doctor in a timely manner. With this service, you register, request a doctor and meet one quickly via your computer or smart device.
Telemedicine solutions that fall into the remote patient monitoring (RPM) allow healthcare providers to track a patient’s vital signs and other health data from a distance. This makes it easy to watch for warning signs and quickly intervene in patients who are at health-risk or are recovering from a recent surgery, for example. This type of telemedicine is sometimes also called telemonitoring or home telehealth.
It has been around for decades, but in recent years private insurers, employers, and government programs have expanded their coverage. By 2016 at least half of U.S. healthcare institutions and hospitals were using some form of telehealth. And last September the Senate passed a bill that will expand Medicare coverage for telehealth services, if it’s signed into law.
