Wifi smartphones have

Cellular data networks have been expanding, their signals have improved, their reach has expanded, and their data rates have increased. One of the primary concerns with our smartphones and tablets is the size of the battery and how much run-time we can get out of them before we have to scamper to find an outlet to plug into.

One of those battery-saving measures they employ is limiting the output of our radios. As you radiate more electrical energy, the draw on your battery increases. OEMs attempt to balance this to an acceptable level: too little power and your distance is limited, too much and your battery drains quickly. Laptops have much larger batteries than smartphones, but they are still somewhat power conscious.

The antenna on my wireless router is 8-inches 20 cm long. As a ham radio operator, I know the value of a good antenna! Now take a look at your smartphone. To make matters worse, what little antenna they did include is usually surrounded by fairly dense and radio-blocking componentry. The WiFi antenna in your laptop is significantly longer, and the one in your desktop computer probably has an unencumbered view to your wireless access point.

Wi-Fi, often referred to as WiFi, wifi, wi-fi or wi fi, is often thought to be short for Wireless Fidelity but there is no such thing. The term was created by a marketing firm because the wireless industry was looking for a user-friendly name to refer to some not so user-friendly technology known as IEEE And the name stuck. Wi-Fi uses radio waves to transmit data from your wireless router to your Wi-Fi enabled devices like your TV, smartphone, tablet and computer.

Because they communicate with each other over airwaves, your devices and personal information can become vulnerable to hackers, cyber-attacks and other threats. This is especially true when you connect to a public Wi-Fi network at places like a coffee shop or airport. Your options for connecting wirelessly at home are growing as mobile networks expand into the home internet realm.

As with internet service, there are advantages and disadvantages to each type of wireless connection, such as speed and strength of signal. Most homes use a wireless router to access the internet these days. The pros include convenience of setup, mobility within range of the Wifi access point router and the ability to connect multiple devices.

The cons: limited bandwidth and reduced speed as more devices are connected to the same Wifi network, as well as potential interference from other electromagnetic devices in the home.

Though Airtel is the first telecom company to support Wi-Fi calling, Reliance Jio came up as the biggest competitor for Airtel and the best Vo Wi-Fi calling provider in the country.

Not only Reliance Jio is rolling out the feature in every region of the country, but it also supports more smartphones. Also Read - Airtel Wi-Fi calling crosses 1 million users. In other words, the iPhone that supports IOS 13 will have the benefit of using wifi calling. Almost all the smartphones that Samsung released so far in the last years will support Voice Over Wi-Fi calling on the Jio network.

Currently, these smartphones do not support Wi-Fi calling on Airtel. Photo Gallery. Are you also disappointed with smartphone brands like OnePlus, Samsung, more for delaying India launch of their products, here s the reason why. Not everyone has faith in the metaverse: Here s why.

When calculating battery drain there are a lot of variables that one must consider, such as distance from the WAP, signal strength, radio noise in the area, and how much data is being sent and received. Using WiFi rather than cellular for data access can yield a significant savings when it comes to battery life — depending on the circumstances. The further you are from a cellular tower, the more energy you need for that data signal to be of any use.

WiFi access points are typically much closer than cell towers, and can therefore use less power to communicate data than cellular.

Of course there are exceptions to this rule, and the observed reality may be significantly different in one situation versus another. These days we like our phones and tablets to know right where we are. They help us get from point A to point B, and geotag our pictures so we know where we took them years down the road. They also enable our devices to do some pretty snazzy things based on where we are, when we enter an area, or when we leave an area. This concept is called geo-fencing.

Like a regular fences, geo-fences encircle an area. What does geolocation have to do with WiFi?
