Connectivity in both wired and wireless forms is part of everyday life. From wired and fibre broadband to mobile communications - 2G, 3G, 4G and 5G, Wi-Fi, Bluetooth and many other wireless technologies through to standards like Ethernet, USB and many others. Wi-Fi is particularly important as demonstrated by the number of Wi-Fi routers, Wi-Fi repeaters and the like that are available for sale.
Mobile phones / cellular telecommunications
Mobile phone or cellphone technology has been with us for well over 40 years and it has now become an essential part of everyday life
Fortunately, the same standards are now used around the world and this enables aspects like roaming, as well as the economies of scale to be gained
However in the early days of mobile communications technology, this was not the case. However as 2G progressed to 3G and then 4G, 5G and then 6G, the standards ahve developed to provide ever greater speeds and ever more capabilities, although one of the main challenges is to provide good coverage and not have calls continually dropping out when on the move.
This addresses a variety of topics associated with wireless conenctivity. Everything from Wi-Fi, Wi-FI routers and repeaters, etc through to other forms of wireless conenctivity including Bluetooth, LoRa, NFC and many more. With the technology for Smart homes and cities becoming more commonplace, these technologies are being used increasingly.
Although wireless technologies like Wi-Fi are widely used, wired connectivity is important. Ethernet is once such example as it is used for many computer conenctions. Items like Ethernet cables and many more can be found, although with other wired connectivity areas like USB, serial communications and networking solutions like NFV and SDN.
