 Wi-Fi 6 + 5G CISCO says in his brochure: Five Things to Know About Wi-Fi 6 and 5G; Both Wi-Fi 6 and 5G are built from the same foundation; They will co-exist and work better together to support different use cases; Wi-Fi 6 will continue to be the access choice for indoor networks; 5G will be the designated choice for outdoor networks; Wi-Fi 6 and 5G expand opportunities for digitization across all industries. Both Wi-Fi 6 and 5G offer exciting opportunities to connect more mission critical IoT devices reliably via wireless. Wi-Fi 6 and 5G will also offer enhanced mobile broadband for immersive experience via augmented and virtual reality. Wi-Fi 6 and 5G introduce the new era of wireless access. Their convergence enables organizations to do business anywhere while increasing productivity and offering the best user experience.

The logo at the beginning of the first paragraph is a creation from CISCO, one of the leading manufacturers of network equipment. My first home router (GATEWAY) would be theirs (Figure 4.4.100b). That was around year 2010. Ten years before that I used an 'Amiga 1200' with which I would occasionally connect with a modem borrowed from my company at a speed of about 5 kbps with some B.B.S. server. Much has changed fundamentally since the age described.

In general, the use of wireless communication with respect to these technologies would be used according to the following figure:

The basic element that devices must have to be an integral part of this technology is the sensor; a part of device that measures, processes and stores data. Depending on the purpose of the device, the sensor can be only one (such as for a gas detector) or more of them for different purposes. This is the first and basic condition. The second condition is that the device has a transceiver that will use the radio-waves to send data to the user or the user will read them. The user can order changes to the device if necessary. There does not necessarily have to be two-way communication, if the purpose is simple, for example, for the device to transmit data about its operating status and correctness.

There are two ways sensors in devices can be read. The first is that the device sensor sends data from a private Wi-Fi network to the public server of the sensor manufacturer with a fixed public address, and the user reads data from a server that will deliver any new user orders to the sensor when the sensor reports to the server again. An important factor is the frequency of contact of the sensor to the server. Another way is that communication between sensors and users over short distances takes place within a private Wi-Fi network, and for longer distances a 'bridge' is used between the public and private network provided by ISP equipment and a 5G gateway to allowed users to access the user's private Wi-Fi network from the public network. By default, communication between the private and public network is only possible if the call was made to the public network from the private network, because the gateway does not allow 'intrusion' into the private network from the public network. Thus, 5G devices must allow the user to access his own private network over greater distances using a public network 'across' the bridge. Basically, the sensor considered in IoT, in contrast to the usual notion of a sensor, is a transceiver system that uses internet technology.

Thus, 5G devices with sensors, smartphones and network gateways are available. Currently, they are entering our daily lives with different features more and more, as the following set of Figures shows. It starts with the cheaper and simpler things that are already advertised in online stores.

Although it looks like a joke, it is not. Families who are in the process of decorating the house when buying everything they need, will get wall sockets and wall switches, light bulbs with dimmable lighting, and household appliances such as a stove, dishwasher, water heater, and other necessities. In this way, they will have control over the operation of all devices in the house. Regarding easy access to the devices, it is recommended to buy everything from the same manufacturer for unique software support. However, it will be a long time before older households reach this stage. And what about women? Has the advertisement shown a bait for a male customer, because with the image of a half-naked woman, the chances of selling the product increase? At which retailer will you buy the same product from even though they are in the same retail space. At women, of course, both men and women. The cult of the half-naked woman in terms of advertising and sales has developed to perfection. After all, women are prettier and more refined than men, which they both know well.

Now we have to wait for what products will be installed in cars, buses, trains, trucks, planes, kindergartens, schools, libraries, museums, hospitals and the like. I guess life with a smartphone will not be complicated to such an extent that we will have hundreds of programs installed on our smartphone for various purposes.

SUMMARY:

It is certain that the introduction of IoT in people's lives will bring about great changes that are shyly appearing so far. For example, smart light switches and dimmable luminaires exist, but cannot be found in all stores, especially if kitchen appliances are sent to them, which send the operating status to the user via new technologies, because they do not change so quickly with new and more advanced. This is valid for the SOHO environment, and outside of it, the introduction of innovations will be even slower. Therefore, this page will be marked 'under construction' for a long time to come.
