Much as Wi-Fi is a marvel of modern technology, it also still really stinks. Two decades of development in, and we still can’t consistently beam Netflix across a house in a consistent fashion. The standard for Wi-Fi is improving, sure, but one group of researchers thinks it should be replaced altogether.

A PhD student in the Netherlands has come up with the concept to use infrared light for data transmission. The concept makes sense in physics terms, as light is more capable of transmitting high-speed data than the 2.4GHz and 5GHz radio waves currently used.

Light has been posited before as a replacement for Wi-Fi, but visible light rather than infra-red. That had slower speeds, more interference, and a requirement to keep your lights turned on all the time. Infrared antenna radiate light at different angles, which means you’ll get coverage in more rooms (although, it also means you need an antenna in each room).

There are still obvious flaws, mostly to do with wiring each room in a house up for an antenna, but as a compliment for Wi-Fi, it would make sense. An infrared transmitter that powers your laptop and game console, and then a Wi-Fi network for more portable devices with less data needs would make sense.

Coming soon? It all depends on what you mean by soon. There are times when the future seems to get here faster than our ability to adapt. And other times the future’s arrival is excruciatingly slow. I’ve been on the public internet since the early 1990s and the pace of change mirrors my statement above. It’s rapid and slow at the same time.

For example, I worked at a local ISP which had 5,000 customers on dial-up, all sharing a T-1. That’s 1.5-megabits per second. Today, we have 100-megabits per second coming to our residence. Yet, at the same time, the public internet chugs along at about 15-megabits per second.

At the other end of the technology scale, the original iPhone was a marvel just a decade ago with a giant touchscreen and easy-to-navigate buttons and applications. Today’s iPhone is capable of blistering 4G LTE internet speeds, 4K video capture, high quality audio, a photos which rival entry-level DSLR’s. And download speeds which average less than the 15-megabit per second speeds most homes receive.

That brings up the difference between total capacity and actual usage, and the future vs. the present. Researchers in the Netherlands have created a wireless network using infrared rays which could be the future of Wi-Fi in homes. They’re harmless, easy to set up and install, and provide 100-times the fastest W-Fi signal; up to 40-gigabits per second.

The way it works is straightforward. Instead of sharing a traditional Wi-Fi signal, the infrared signal follows the device and delivers all the bandwidth to each device; no sharing on each infrared signal. The light’s wavelengths make data capacity far greater. For downloads.

Therein lies yet another technological rub. Infrared Wi-Fi is fast at downloads, slow at uploads. And it still doesn’t account for how slow the public internet remains, although 5G mobile standards may change that forever.

Many such technological advances are slow to market because there’s a gotcha already present, and infrastructure isn’t keen to allow in something new, even if better, because it’s not economically feasible.

A home internet Wi-Fi system that is faster than the internet connection still gets bottlenecked at the door. Faster home Wi-Fi won’t change that. For example, our home router and most of our devices can handle a few hundred megabits per second downloads, but only reaches such speeds during tests, not during real world usage, and the ISP only provides 100-megabits per second anyway.

Technology for the masses moves forward in fits and starts. For example, under developed countries often cannot afford the infrastructure required for telephone land lines, and expensive cable television and internet connections, but can have rapid mass adoption of cell phone towers which are less expensive to set up and expand.

Infrared Wi-Fi looks like a great idea, but it has both an infrastructure problem and an upload speed problem to solve. Don’t be surprised if another solution comes along before the infrared Wi-Fi system makes it to market.

Think twice before you set up the office aquarium.

Nothing grinds a workplace to a halt like a lack of internet access. Gone are the days of hard-wired desktops in every office. Work environments increasingly support staff and guests with Wi-Fi, which can create a surprising amount of strain on your office wireless network, especially given the rise of devices connecting.

You might be surprised what everyday items and situations are bringing your network to a crawl. Here are the top 12 common issues impacting every office, no matter how small or large.

1. Tinted glass.

You’d think your Wi-Fi signal would sail right through, but it doesn’t. Tinted glass often has metal additives that can heavily absorb Wi-Fi signals. So if your office is full of wall-to-wall windows or glass conference rooms, it’s going to impact your signal.

2. Mirrors.

These are huge Wi-Fi vampires. Mirrors can cut signal strength up to 50 percent because they reflect back the signal. If the bathroom is between the router and your desk, it’s part of the problem.

3. Water.

You may love that aquarium in the office, but water, just like glass, is a massive Wi-Fi killer due to its density. It absorbs and traps the signal. If you’ve ever seen your signal drop at the beach or near large bodies of water, that’s why.

4. Chicken wire.

Metallic mesh — AKA chicken wire — is a common construction material, which means your walls are lined with metal. Metal is also a gobbler of your Wi-Fi signal. The way around this is to ensure you have enough equipment to make up the difference. You might need an extender or access point to boost the router signal.

5. BYOD.

Also known as “Bring Your Own Device,” is a huge trend that’s taxing most workplaces. Most routers tap out at 10-20 devices. With today’s proliferation of tablets, smartphones, laptops and wireless office equipment, like your printer or that precious Apple TV in the conference room, bandwidth gets zapped quick. Plan accordingly.

6. Board meetings

We’ve heard more than one horror story of IT staff scrambling as networks crash under the weight of all your board members downloading a 20 MB presentation at the same time, in the same room. Avoid irritating your board. Make sure your bandwidth is up to snuff before the meeting starts. Better yet, give them their own channel.

7. Too many separate Wi-Fi Networks.

It’s not uncommon in some office environments, often without formal IT staff or consults, to jerry rig a system together and load up the office with a several different routers running on different channels with different passwords to increase coverage. Problem is, Wi-Fi networks in close proximity can interfere with each other, let alone the pain of logging on and off networks. Make sure you have someone set up your system so each router or access point is on the right channel for limited interference.

8. Poor spacing.

It’s very important to adequately estimate needs and space equipment throughout the office to ensure a consistent supportive signal. In other words, don’t lock your one router for the whole office in the back cabinet and seat your graphics team near the front, by the glass doors.

9. Below-grade equipment.

A number of businesses use equipment provided by their ISP or bottom-shelf routers and then run into performance issues. When setting up Wi-Fi for a small business (1-3 employees), as a minimum, invest in a high-end consumer router. When adding more employees, move to business grade at the beginning. The headaches of the network down during the board meeting aren’t worth the little you save going low-end.

10. File cabinets.

Wireless signals degrade going through metal so don’t place your routers or access points in a room filled with file cabinets. It might seem obvious, but you’d be surprised how often it happens.

11. Your kitchen.

It might have the snacks, but it also has major appliances that eat away at Wi-Fi strength. Refrigerators and especially microwaves provide interference, so keep equipment out of the range of the kitchen.

12. People.

Really? Absolutely. The human body is 50-65 percent water, and crowds of people at an office party can be a highly effective barrier to Wi-Fi.  Mount your access point in the ceiling to minimize the chance of interference by your coworkers.

Now that you know the main reasons your office Wi-Fi stinks so badly, you can fix it. More than likely it’s due to having underestimated the level of equipment and support your business needs. If you’ve got more than three people working out of a space, or you open your Wi-Fi up to guests and staff, spring for business-grade equipment.

Unless you work in a small one-room studio, odds are you need a range extender or an access point to distribute the signal throughout the space without it degrading and hanging up that board of directors meeting, or worse, VC pitch. Don’t let it happen to you.
