How can the range of WiFi for smart-home devices be increased?


WiFi provides cable-free network access and makes a significant contribution to easy internet usage. WiFi allows you to use your laptop, smartphone or tablet within its coverage to surf or take part in other online activities. Also, many devices, particularly smartphones and tablets, do not have a wired network interface, so they need a WiFi connection. Furthermore, wireless access points’ transmission power is limited, meaning that the maximum range is also limited. Factors for interference can also conflict with the Internet connection. Nonetheless, you should take steps to improve your WiFi range

Increasing WIFI Range

The Typical Way

Wifi is one of the internet’s most important developments as no one wants to be chained to a desktop. But it’s also one of the most frustrating components if you are plagued by slow speeds, bad reception, and other wifi problems. Here are ways that you can use to power your home wifi.

1. Choose a good location for your router

Avoid placing the router near metal objects and electrical wave-emitting equipment. Metal is the WiFi signal’s highest disrupter and its presence around a WiFi router will effectively produce a large dead zone.

2. Keep your router up to date

Once a router is corrupted with malware, it can steal bandwidth and spread to other devices across the network. But even without a harmful malware threat, routers with outdated firmware are doing worse than newly updated routers.

3. Get a more efficient antenna

Many WiFi routers come with low, weak antennas while strong WiFi antennas appear to be very large. Compared to your modem’s antenna, which is only a few inches tall and has a gain of about 4 dB, a 10-dB antenna can be about 10 and 15 inches tall everywhere.

4. Cut WiFi Leeches off

In this day and age, an encrypted, password-protected Wi-Fi is a must. The hunger for open, fast WiFi networks is real with more people than ever relying on WiFi. With a good key that can not be easily cracked, you can encrypt and secure your WiFi.

5. Provide a WiFi Repeater/ Booster/ Extender

WiFi repeaters are relatively simple tools that take an existing signal from your WiFi router and retransmit it as a new network. The new network is just an enlargement of your main network, and all the data that passes through it also passes through the main network.

6. Change to other WiFi Channel

Just like the highway lanes, several WiFi streams can be transmitted by a WiFi router. Although most countries have six non-overlapping channels, most users choose the default channel to their router. As too many packets are trying to drive on the same track, it results in a WiFi traffic jam. The solution is simple: figure out which channel is the least busy and turn to it.

7. Bandwidth management of hungry apps and consumers

To make download and upload rates come to a crawl for everyone else on the same WiFi network, it needs only one bandwidth-hungry program or user. Fortunately, current routers offer features such as QoS (Quality of Service), allowing users to privilege certain programs over others.

8. Use the latest technology for WiFi

To take advantage of the new WiFi solutions to improve your WiFi at home, you need to ensure that they are powered by both your home router and your WiFi-enabled devices such as smartphones and laptops.

9. Shift to 5 GHz

The wireless frequency of 5 GHz offers faster data speeds over shorter distances and is usually much lower than the cellular frequency of 2.4 GHz. Consider switching to it for an immediate short-range boost if your router supports it.

10. Don’t hesitate to boot again

The classic IT recommendation, “If it doesn’t work, try to turn it on and off,” often refers to WiFi routers. A quick reset is often enough to boost WiFi performance tremendously. A reboot clears the memory of the network and enables upgrades to be enabled.

The New way

These days, It has become a requirement to have good Wi-Fi connectivity that reaches every corner of the house. Yet securing a whole house or a whole area with a single router is sometimes challenging. That’s why extensions of the Wi-Fi range and mesh networks are common but not sufficient. That is why additional equipment needs to be purchased.

Researchers headed by a professor at Brigham Young University (BYU) in the United States have found another way to increase the base wireless router’s Wi-Fi reach by as much as 60 meters (200 feet) through just modifying the code. This means no extra hardware is needed.

An On-Off Noise Power Communication (ONPC) application interface can be programmed using the same hardware right on top of the existing Wi-Fi protocol. Wi-Fi typically requires one megabit per second (1 Mbps) bandwidth to sustain a signal, but one bit per second is acceptable with the ONPC protocol. This enables communication to be maintained over a longer distance.

BYU states that the system would allow you to transmit a sequence of 1s and 0s, triggering and deactivating signals that suit specific patterns, helping you to keep the connection alive and control the impulses that are connected to the transmission.

“If the access point (router) detects this message, it means,’ OK I know the sensor is still alive and trying to reach me, it’s out of range explains Professor Neal Patwari from the St. Louis University of Washington. “It’s a question of submitting 1 bit of information saying it’s alive.”

The ONPC protocol enabled researchers to expand the range of a network beyond the regular Wi-Fi range by 67 meters in trials.

Nevertheless, note that the ONPC protocol is not intended to replace Wi-Fi or even wireless long-range protocols such as LoRa, but is intended to complement Wi-Fi. The group proposes that smart home systems that just need an on / off signal like a garage door detector, an air quality meter, or even a sprinkler system might be good enough.
