Robotics breakthrough: Scientists make artificial skin

Artificial skin, a groundbreaking innovation in the field of robotics and biomedical engineering, has recently witnessed remarkable advancements, propelling the development of highly sensitive and responsive materials that mimic the properties of human skin. Scientists and researchers globally have been pioneering efforts to create artificial skin with the aim of enhancing the capabilities of prosthetic limbs, robots, and medical devices, while also exploring applications in fields such as healthcare, robotics, and human-computer interfaces. Mimicking Human Skin: Artificial skin aims to replicate the intricate features and functions of human skin, which is a complex organ capable of sensing various stimuli, such as temperature, pressure, and touch. Creating a synthetic substitute that can effectively emulate these sensory abilities has been a significant challenge. Material Development: Researchers have been experimenting with a range of materials and technologies to develop ar...

Fixed wi-fi router with 4G SIM: connect when ADSL is missing

Not all of Italy is covered by an ADSL network: mobile networks help us considerably in this, which cover the territory in a much more widespread way, guaranteeing, practically everywhere, the possibility of connecting to the Internet.

Internet everywhere without ADSL

Not everyone wants to enter into a contract with a fixed telephony provider: for a holiday home, for example, it could be much more useful to turn to one of the many offers on the mobile operator market to cover those connectivity needs limited to a few months. 'year.

It is also very likely that in the mountains or in places less served by the sea the ADSL just does not arrive and then the only alternative to connect to the Internet is that offered by mobile operators.

Home automation services for the holiday home

Also for second homes, then, the need to integrate more advanced  home automation services can make sense: for example, to remotely turn on a wi-fi air conditioner and heat (or cool) a room before arriving, to control who accesses via wi-fi sensors or to have the possibility to install wi-fi security cameras.

A portable 4g wi-fi router , in these cases, may not be the right choice and you need to turn to something more stable and definitive like a traditional wi-fi router, but one that can take advantage of the connectivity of mobile networks without too many headaches.

What are Wi-Fi routers with SIM cards

The "fixed" wi-fi routers with built-in SIM card help us: they have the traditional appearance of a common wi-fi router, but instead of hosting an ADSL or VDSL modem (for optical fiber ), they offer a slot for a card SIM that "powers" a 4G modem . Without major complications, they automatically configure themselves as a smartphone and we only have to choose the right place to place it.

Thanks to the adjustable external antennas, this type of wi-fi router allows better signal sensitivity, managing to pick up the 3G or 4G signal even where a smartphone fails and a portable 4G router struggles.

Furthermore, with the help of some tricks to improve the 4G signal, it is possible to further improve reception even in particularly difficult places.

Using this type of 4G wi-fi router is not a "poor" choice: there are, in fact, models compatible with 802.11AC wi-fi and able, therefore, to offer an excellent level of performance even for connected users .

Other models, on the other hand, aim at essentiality and economy, trying to offer a product that works immediately without any effort for the user.

In short, the choice is not very wide, but there are some valid models on the market and the costs are not exorbitant.

What is certain is that a good wi-fi router with a fixed SIM card is a more durable and stable choice than a portable model, which offers an advantage only for those who travel a lot: so, if you are looking for a good wi-fi router for holiday home, or you are in the city and don't want to pay the cost of an ADSL, consider one of the models I have selected below.
