5G?

If you believe this then you have no understanding how 5G works.

The very high frequency of these signals is important to note. It means that 5G will be capable of incredible data bandwidth, so that many people will simultaneously send and receive nearly unfathomable amounts of data.

Benefits

Up to 10Gbps data rate – > 10 to 100x improvement over 4G and 4.5G networks
1-millisecond latency
1000x bandwidth per unit
areaUp to 100x number of connected devices per unit area (compared with 4G LTE)

According to the February 2020 issue of Fortune Magazine, average 5G speed measures done in Q3/Q4 2019 range from:

220 megabytes per second (Mbps) in Las Vegas
350 in New York,
380 in Los Angeles,
450 in Dallas,
to 550 Chicago,
and over 950 in Minneapolis and Providence approximately.

That’s 10 to 50 times more than 4G LTE.

But here is the part where you understand 5G is a lot more than that.

What is 5G low latency?

5G technology offers an extremely low latency rate, the delay between the sending and receiving of information. From 200 milliseconds for 4G, we go down to 1 millisecond (1ms) with 5G.

The downside? High frequencies have short range, and 5G may only be able to span a few blocks of any given area. That means 5G may not project over long distances. Smaller frequencies also don’t penetrate obstacles very well, so everything from concrete walls to tree leaves may disrupt signals. That makes it a line-of-sight technology – your wireless modem or phone will need to be close to a base station for best transfer speeds.

In addition to better bandwidth, 5G should have reduced latency, or delay, between the devices it connects. 4G has a latency of around 70 ms (milliseconds); 5G should have less than 1 ms [source: Mobile Foresight]. That means less frustration and more productivity, and in some scenarios, it’s a lifesaver. With driverless cars, for example, the vehicles must be able communicate on a nearly instantaneous basis to prevent accidents.

5G’s infrastructure rollout will be different, too. In the past, communications companies typically build big cell phone towers to propagate cell signals throughout a geographical area. 5G may alter this paradigm. Rather than constructing towers, service providers will just install their equipment (called small cells) on existing telephone lines and buildings. The cells may have a range of around 250 meters (820 feet) [source: IEEE]. To tap into the signal, customers will use wireless modems (or phones) to connect. In turn, that could mean you no longer need that cable-based internet service.

Because millimeter wave 5G signals have weaker propagation compared to 4G, service providers will have to create a denser infrastructure to ensure consistent service. As with WiFi, 5G will require more base stations in closer proximity to serve many people.

A few mobile carriers are launching “pre-5G” versions of 5G that would lead you to believe that 5G is already a well-defined standard. It’s not. In fact, no one really knows just yet what 5G will be like because the standard for 5G won’t even be finalized until 2018 [source: Frenzel].

A lot of what 5G really will entail is still in the realm of speculation. One thing’s for certain: 5G will be an improvement over 4G in terms of speed and capacity. If there’s a drawback, it’s that the upgrade process will be expensive. Service providers will blow billions (perhaps as much as $21 billion) to make the jump from 4G to 5G [source: Real]. And consumers will have to pay up too.

“5G cell towers are more dangerous than other cell towers for two main reasons. First, compared to earlier versions, 5G is ultra high frequency and ultra high intensity.”

“Second, since the shorter length millimeter waves (MMV) used in 5G do not travel as far (or through objects), with our current number of cell towers the cell signal will not be reliable.
