Happy Birthday WiFi

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.

5ghz vs. 2.4ghz

WiFi comes in two flavors 5ghz and 2.4ghz, but many do not know the difference.

2.4ghz travels father and penetrates walls and other objects better but is not as fast as 5ghz. Many more devices use the 2.4 ghz band, like baby monitors, RC toys, and Xbox controllers.

5 ghz has higher speed, shorter range, and lower penetration through walls and obstacles. It also allows for more throughput.

Bottom line, if your device is close to the router or the router is in the open rather than hiding in a niche of your house, 5 ghz is better.

Incidentally, 5ghz should not be confused with the new phone 5G and 5G LTE networks, which use much higher frequencies in the 30 ghz to 300 ghz range. It has the potential to be 20 times faster than 4G, meaning you can download things 20 times faster or download more data in less time.

5G Requirements

Many have heard or seen phone companies touting their 5G tests around the country. 5G is required to be backward compatible with current technology at current speeds. So there is no need to worry about forced change. . . yet.

However, your current phone is not 5G capable and will not be. You will need to buy a new phone to have it connect to 5G. Motorola is pushing to have the first 5G phone available this month ($480 from Verizon). Others will follow and by early next year there will be more choices.

Also, your current modem/router will not work with 5G, nor will your PC. Intel is currently working with Acer, ASUS, Microsoft, Dell, HP, and Lenovo to deliver laptops and convertibles with the new 5G standard. Companies are working on 5G modems that will fit into phones, cars, smart-home devices and other device forms that have yet to be developed, like maybe carrying a puck type portable modem in your pocket.


Bottom line, if your phone works and your cable or streaming service works for TV now, do not be in a hurry to change all your equipment. Let others suffer the slings and arrows (and costs) of the new technology. Be patient and do not be first in line. It will take a few years to have 5G available everywhere. 5G phone service will be available before home 5G. When home 5G does, be prepared to spend big bucks and deal with learning new equipment. Incidentally, the 2020 Tokyo Olympics are expected to broadcast in 5G with 8K TV resolution.

Next Generation TV and 5G

Next Gen TV is an internet based system, which means it can carry internet content along with traditional over-the-air broadcast signal. It provides new services like video on demand, mobile viewing, 4K Ultra Hi-Def, enhanced emergency alerts, a high frame rate, more colorful picture, and immersive audio – all delivered free with an over-the-air antenna. It is based on the ATSC 3.0 standard. Although current over-the-air TV antennas are able to receive the new signals, there are no TVs, no converter boxes, and no DVRs on the market in North America today that support ATSC 3.0's Next Gen TV.

Next Gen TV is totally separate from 5G. Basically Next Gen TV is for free over-the-air TV and 5G is for communications. 5G will provide wireless to the house and is likely to offer the strongest competition to the world’s free, over-the-air broadcast model. Planned 5G services may offer multiple content streams, 4K, support for new video standards, mobile reception, and on multiple devices. Vendors, carriers, and broadcasters trying to be first to market are feverishly spending billions to set up new signal boxes, antennas, and repeaters for both technologies. (editorial - Cord cutters, millennial lifestyles, and people opting out due to poor service and high prices have forced vendors to find new ways to drill into our wallets.)

Next Gen TV was specifically designed to support mobile uses like rear-seat entertainment and navigation systems in vehicles, in addition to phones and other portable devices. We will be able to watch broadcast TV in a moving car with a better signal than we receive in our living room today.

Here are main points of the ATSC 3.0 Next Gen transition:

  • 4K Ultra HD Video
  • High dynamic range (HDR) color management
  • 1+4 surround sound and immersive audio
  • More multi-casting - over 100 sub-channels per main channel, which means potentially hundreds of over-the-air channels per market
  • More reliable and robust transmissions less prone to interference
  • Indoor reception will be much easier with an antenna
  • Will allow two way communications with the broadcaster to choose viewing angle on sports, etc.
  • Will allow targeted advertising to particular demographics
  • More detailed show info, actor bios, etc.
  • Immersive and Virtual Reality experience.
There is much hype with the transition, but it will be a lengthy process. Some carriers, such as AT&T, Verizon, etc., are testing now in Dallas and Phoenix. Other cities are planning to begin testing soon. There are currently no broadcasters transmitting in 3.0 (other than as tests) and they will not be until likely 2019 at the earliest. It will all depend on when a station decides to make the switch. To take advantage of this new technology, consumers will need a device with a 3.0 tuner chip set. One TV maker, LG is planning to offer TVs this year with a combination of the current 1.0 tuner and a 3.0 chip included. A tuner is a device or computer chip that provides the TV Guide capability.

Bad news is that all of the Next Gen and 5G technology deployment will cost consumers a bundle for new phones, TVs, PCs, routers, and tuners. In addition, we should be prepared to see rates go up as early as this year,because the purveyors seek to recoup their investment as soon as possible. Next gen TV will not require an internet connection, but some features will not work without one.


Good news is that there is not a hard turn off deadline for ATSC 1.0 (for TVs) or 4G LTE (for phones and other devices). There is no specific date when all of a sudden there will no longer be 1.0 or 4G and everyone will be broadcasting in 3.0 or delivering 5G as there was with the conversion from analog to digital TV. No need to put off purchases now for either, as both will be a few years from full deployment. As with all new technology, prices will fall hard and fast as widespread adoption takes place.
