Current wireless technologies
Current technologies and networks permit various devices to send data to each other and
also to the web without the use of cables. The current wireless technologies which we shall
discuss includes; WIFI6, 5G and, and Nano-satellites. These technologies are mostly used in
real-time applications and below our discussion on how these technologies are used in real time
application as in [5].
Wi-Fi 6 is a current technology which is set to become faster and better with its
upcoming main update. Due to that, there are enough routers which are consist of chips, then
802.11ax Wi-Fi will never be fully implemented until December 2019, leading to updated new
wireless capabilities that will give towards the next generation network with less congestion and
more speed. High-efficiency wireless currently known as 802.11ax will be referred to as Wi-Fi 6.
The naming convention which will be set up by Wi-Fi alliance will include Wi-Fi 5(802.11ac)
and Wi-Fi 4(802.11n) as in [4] Wi-Fi 6 will be consists of a single user data rate that is 39%
faster than 802.11ac, but what is very crucial is that the specification update will be in a position
of offering four times the throughput per user in the environment which is very crowded for
example [4]. For the various improvements in this technology, 802.11ax implemented a varies
changes which include multi-user technologies which come from the cellular industry such as
OFDMA and MIMO methods that improves performance and capacity by supporting series of
connections. The strength of Wi-Fi is that it allows users to connect to multiple devices over only
one network. In addition, can connect devices in long distance distances without the use of the
cable. The weaknesses of Wi-Fi are that they are more expensive, slower and less secure.
Concerning security issues, WIFI can be vulnerable to data exposure when weak passwords are
