Mobile hotspots are known by a range of other names, including portable Wi-Fi routers, pocket Wi-Fi, mobile Wi-Fi devices, portable hotspots, Mi-Fis, and more. Whatever you call them, though, they all work in much the same way.
When it comes to download speed, the Nighthawk M1 is almost unparalleled in portable hotspots. Support for a range of confusing networking acronyms including LTE Cat16 and 4×4 MIMO translates to downloads at up to 1Gbps, and uploads of 150Mbps.
We have successfully developed a new cardiac auscultation simulator by applying recently developed digital and computer technology, which digitally records, stores, modifies, and plays back heart sounds and murmurs characteristic of various heart diseases. The simulator is capable of playing back different heart sounds or murmurs at each auscultatory site (aortic, pulmonic, tricuspid, and mitral) of a human chest-sized mannequin (made of urethane foam), through four built-in speakers. We were able to listen to accurate reproductions of heart sounds and murmurs at the same timing as in real patients by any type of stethoscope used in routine medical practice. This compact and portable educational apparatus, which simulates realistic auscultatory sounds, will impact greatly on the medical training of cardiac auscultation for physicians, medical students, nurses, and paramedicals.

This paper will develop a portable ECG monitoring and processing system that has the capacity to observe subjects in real time and display the resultant ECG signals on a computer or laptop. In order to accomplish this, a Graphical User Interface (GUI) was developed that is compatible with LabVIEW and with MATLAB data processing techniques.
Typically, when a patient with cardiac disease is identified as requiring observation and/or diagnosis, this requires hospital admission. This observation and diagnosis generally require the use of an ECG machine which, due to expense and the need for expert operation, is generally only found in large, centrally located hospitals. Treatment, therefore, is likely to involve significant inconvenience and expense for patients. There is hence a real need for a portable and economical ECG devices. The need for such a device to be wireless stems from the requirement with current ECG machines for patients to be attached to the machine by electrical wires, thus requiring the machine and patient to be in close proximity. A wireless machine, however, would facilitate patient and machine not being physically proximate. In this project, a portable wireless ECG monitoring and processing system was designed which is capable of performing all the functions of centrally based existing ECG machines, but utilising wireless technology to make connections with centrally based nodes. This was accomplished by patient-connected electrodes fitted with micro-modules that have the ability to process digitally and wirelessly convey obtained signals by means of ZigBee module transfer methods. The different aspects of the design were tested and evaluated as depicted in the following section.
A mobile phone[a] is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called cellular telephones or cell phones in North America. In addition to telephony, digital mobile phones support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access (via LTE, 5G NR or Wi-Fi), short-range wireless communications (infrared, Bluetooth), satellite access (navigation, messaging connectivity), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.[1]
A handheld mobile radio telephone service was envisioned in the early stages of radio engineering. In 1917, Finnish inventor Eric Tigerstedt filed a patent for a "pocket-size folding telephone with a very thin carbon microphone". Early predecessors of cellular phones included analog radio communications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation (0G) services, such as Bell System's Mobile Telephone Service and its successor, the Improved Mobile Telephone Service. These 0G systems were not cellular, supported few simultaneous calls, and were very expensive.
I'm kind of disillusioned with MS/UB support for the past few years. Virtually no bug or feature has been updated since V14 originally came out. Many bugs I've reported that were claimed to be fixed in the next update have never been fixed, and it has been years for some of those. NI support contract is not cheap and I feel NI has misplaced it's resources working on portable sims and web stuff that means nothing to actual serious users of the app.
What is the current offering that would be better than MS Blue? All I know about is they can install regular multisim for a 30 day eval, but that doesn't really work for a customer who only needs to tweak a file once or twice a year.
As we discussed above, for your specific application, the eval extension is the best approach. Unfortunately, there isn't a better offering for occasional annual viewing of Multisim files. But depending on the complexity of the circuit, Multisim Live might work for you. It now includes both analog and digital components at multisim.com.
A cellular booster will boost weak cellular signals for a single device when placed in close proximity to the booster. When we first started RVing full time we relied on our portable WiFi device for internet. We got a cellular booster and placed the Jetpack (or an iPhone) in the cradle to boost the signal, as needed.
In this study, the possibility of recording multiple-lead ECG using dry capacitive electrodes with a custom-developed portable device was investigated to explore the feasibility of a wearable ECG device with electrodes embedded into clothes. The performances of an electronic interface proposed by Chi et al. [25] and others [26,27] were evaluated by characterizing it with simulations and electrical tests in order to deeper investigate its performances. Moreover, the studied electronic interface was implemented into a custom realized portable device, and in order to verify the effectiveness of the system, a comparison between signals obtained using the developed device, with dry capacitive electrodes, and a commercial heart rate front-end IC, with standard wet electrodes, was performed.
Moreover, we developed a portable device based on the presented electronic layout. The output signals of the electronic interface are acquired using the 12-bit SAR ADCs of the ESP32 microcontroller (ESPRESSIF SYSTEMS, Shanghai) with a sampling frequency of 250 Hz. The ESP32 microcontroller is equipped with an internal Bluetooth module; thus, it is capable of transmitting digitized signals through a wireless connection to a PC or smartphone. The device is battery operated.
To evaluate the effectiveness of the contactless ECG device, we performed a comparison between signals obtained using this device and those obtained using an AD8232, a fully integrated single-lead ECG front end by Analog Devices, using standard wet electrodes. The AD8232 is an integrated signal conditioning block for portable ECG devices and other biopotential measurement applications. It implements a filter and a differential amplification stage. To improve the common-mode rejection of the IC, it includes an additional amplifier for the right leg drive [53].
Fortunately, portable Wi-Fi hotspots are the perfect solution for travelers and digital nomads to stay connected. These compact devices provide a high-speed connection wherever you go, so you can get your work done (and pay the bills) while exploring new locales or camping beneath towering evergreens.
A portable Wi-Fi hotspot is a pocketable device that uses a cellular signal to create your own Wi-Fi network. These hotspots typically output both 2.4GHz and 5GHz Wi-Fi connections, and connect to the internet through mobile networks that transmit cellular data through radio waves, called frequencies. This means that you can connect your laptop, tablet, or smartphone to the internet even if there is no public Wi-Fi available. Portable Wi-Fi hotspots are sometimes also called "Mi-Fi" devices.
To get your portable Wi-Fi device connected to the internet, you will need to purchase a prepaid data plan or local SIM card. If you plan to use your Wi-Fi hotspot for international travel, look for a device that has prepaid data plans available. Purchasing a prepaid plan prior to leaving on a trip means you can skip the hassle of locating a foreign service provider and picking up a SIM card.
The MightyWiFi is a SIM-free hotspot that supports 29 frequencies on the 4G network which provides you with coverage in over 150 countries. This hotspot has flexible global data plans that are prepaid, ranging from 3GB to 30GB. The 5,000 mAh battery also doubles as a portable power bank with up to 12 hours of usage. The MightyWiFi supports up to five devices at once. 2b1af7f3a8
