This year is the twentieth anniversary of the formation of the
Wi-Fi Alliance and the launch of commercial Wi-Fi. Back in 1999
computers were about the only devices that could take advantage
of the new technology. Finally we could move around the house
without extremely long wires trailing behind. Current estimates
show there will be about 10 billion worldwide Wi-Fi connected
devices in 2020.
WiFi uses radio waves
to provide high speed connections. Today everyone is talking
about 5G being the next big wireless move to replace WiFi. The
difference is that 5G uses cellular technology, not radio waves.
It is the fifth generation cellular and will replace current
fourth generation, 4GLTE phones.
What it means to the common person is that there will be no
wires necessary to connect everything in the home. It really
does not matter if that means WiFi 6 (the newest standard) or
5G. The difference will be felt in the wallet. 5G is very
expensive to rollout and repeater towers will be needed across
the county (in some places as close as every 1 to 2 thousand
feet). WiFi just needs to travel from your router/modem, in your
house to all connected devices.
Billions of devices will need to be replaced as 5G is not
backward compatible. The same is true for WiFi 6.
For all the wonderfulness of both of these technologies, a wired
connection still provides the best TV watching with little to no
buffering and the fastest way to take advantage of surfing the
internet.
My advice, ignore both for at least a year, maybe two or three
years. Let the others share the slings and arrows (and high
cost) of new technology. However, when the new ATSC3 (NEXTGEN
TV) standard comes available in your city next year or the year
after, get a dongle to hang on the end of your antenna cable and
be happy with no-cost, free, interactive TV.
Incidentally WiFi is
not an acronym, think of it like haagen daz, it is a made up
name.
