7.6.3. Homebox - Mobile Internet

Fast Internet has become a completely understandable thing we expect to use wherever we are located. But in reality this is not always the case. Optical and cable communication links allow speeds above 100 Mbps, but this is mostly available in cities. Even in the city center can be 'stuck' at low speeds, if the distance from the ISP center is large and there is no good VDSL connection, or cable Internet is not available. In smaller pueblo, the Internet is almost unknown. The solution is a mobile Internet that provides acceptable communication speeds on 4G / 5G networks. For this purpose, a device called 'Homebox' is used. One of the major advantages of mobile Internet is that the device can take with you, in a weekend cottage or hotel room on vacation, include it in electricity, and the device is ready to work immediately. Additionally, if the device has a built-in rechargeable battery (like a smartphone), it can also be used on a picnic where there is no power connection. Helpful, because you do not have to think about whether someone is offering fast internet at the location you've gone.

In all variants, the Homebox is actually a mobile phone packed in a different case and has the ability to achieve the network connection inherent in a SOHO device and to connect a regular phone to it. In each of these devices, the SIM card is identical to the one in the mobile phone. The Homebox device is for users who do not have any possibility of introducing a real fixed connection to the house, either wired or cable. Anyone who has a need for the Internet and a phone, and has the ability to use a real landline has virtually no reasonable need for a Homebox. Advanced Homebox devices can effectively serve as a variant for using the Internet and its services to undemanding users, who do not need a lot of additional devices (say printer, NAS, multiple computers, server, etc.) with which to fill their work environment. This type of connection to the Internet and the use of the phone is usually not a bad option if there are no other options.

The next set of images shows a new generation of homebox device 'HUAWEI 5G CPE Pro 2'.

This devise is the latest generation of HUAWEI routers, as homebox device as a counterpart for classic SOHO devices. In home envionment maybe is good solution to use some switch to make network backbone, so network stays in function i case of no Internet conection. Esential spcification for Homebox at Figures above is:

The description is not very rich in technical details, but the data shown are only available from the currently available documentation. According to the description in the chapter on smartphones, it can be concluded that data of the Low band and High band frequency spectrum are missing. The data in the table refer primarily to Mid band. If you look carefully at Figure 7.6.41c, you can see that the design is very compact and functional, and that the four antennas enable efficient data transmission. Today, with modern electronics it is not a particular problem to make the antenna electrically longer or shorter than its physical length, because the antenna is most efficient if it is a large half wavelength of the radio waves used and best receives or transmits a radio wave in a direction perpendicular to its position - around the antenna. Each radio wave has an electric and a magnetic component that together form an electromagnetic field, and the position of the electric field vector corresponds to the position of the antenna (they are in the same plane) and its position relative to the earth's surface (horizon) determines the polarization of the radio wave. It is important that the antenna at the receiving point has the same polarization as the transmitting antenna from the ISP. The arrangement of antennas in the shown device is such that quality reception of radio waves is ensured from almost all directions, which in these technologies are almost always vertically polarized, and since radio wave radiation is most efficient around the antenna, the communication range increases. Namely, as the antenna radiates best in a direction perpendicular to its position in vertical polarization, the propagation of radio waves relative to the horizon is uniform in all directions, similar to the scattering of light at lighthouses. Therefore, it can be seen in all brochures that the device antenna (eg SOHO gateway) is placed vertically.

I am not sure that the LG smartphone and HUAWEI homebox shown meet all the requirements for using all three of these frequency ranges. If they possibly meet the above, it is not specified in the available brochures and instructions, and it is not of much importance at this time because the ISP infrastructure for new technologies does not exist or is at the very beginning of introduction. At this moment, the most important thing is their compatibility with current standards in order for these devices to be usable, and they meet that. Probably for these smaller devices it will not be a problem to upgrade the firmware when needed, but what requires a large investment and solid standards are the transceiver stations of the ISP and each of the possible 'sensors' wherever Wi‑Fi 6 and 5G is applied.

The content will be updated in accordance with new knowledge!

SUMMARY:

It can be concluded that Wi‑Fi 6 in the community with 5G technology is quite neat and 'made up' and that the devices are new devices ready to use them, but for now they use existing standards because much more is missing for full functionality. Considering only the SOHO environment, it will be another few years until all user devices are replaced with new ones that will be able to use the new features of the newly described technologies. Therefore this page should be taken as operational one that will be updated over time.
