Tello Extended – 2X to 5X Your Range with the Xiaomi Mi WiFi Extender

The Ryze Tello is controlled via a WiFi connection to your Smartphone. We wanted to boost the power of this signal and see if we could eek out some more range and better video transmission from the Tello. We did some research on antennas and by far the most popular budget option seems to be the Xiaomi (pronounced shaow-me) MI WiFi Extender. So we got the MI Wifi extender to give it a shot – we were not disappointed. Once you know a few tricks, the setup is easy. Read on to learn more. For another solid review of the Tello check out this post on www.dronedj.com.

Xiaomi Wifi Extender with DJI Tello

We recommend a rectangular battery backup to help keep your WiFi antenna oriented correctly.

What You Need

  1. DJI Tello (OK, it is really a “Ryze Tello”). Learn more about the Tello with our full review and video.
  2. The Xiaomi MI WiFi Extender. You can get it for less than $15 from Amazon.
  3. A USB Battery Backup. We recommend a rectangular shape to sit flat on any surface and hold your antenna up vertically. Buy a well-reviewed battery from Amazon for under $20.

How Does the MI Wifi Extender Work?

The MI WiFi Extender (or WiFi repeater) works by going between your connected device and the WiFi source. It passes the information between the connected device and the source, thereby extending the range between the two. In your home, the source will typically be a WiFi router, while the connected device is your smartphone, tablet, computer, smart TV, etc.

We typically only think of an extender working if it is positioned at a midpoint between the source and the connected device – but that’s now how we used the MI WiFi Extender.

When flying a drone you can’t position the extender between your controlling device (smartphone) and the source (the drone). Assuming you keep the extender near the pilot, the only way the extender helps is if its antenna is somehow superior to the antenna in your phone. Is it better? Let’s find out.

How Much Extra Range?

We tested the MI Wifi extender with the Ryze Tello to see how much range it has with the default Tello network as compared to the network created by the MI Wifi Extender. The results were shocking.

We tested in two locations. At the first location, we got about 100 feet (30 meters) of range without the extender and 250 feet (75 meters) with the MI Wifi extender. That’s a 2.5X improvement. Not bad. At 250 feet your Tello is a small spec that requires 20/20 vision to see.

Tello Range Test Map

At our first test location, the Tello flew more than 200 feet in several directions.

We did even better at the second location. We were again only able to fly about 100 feet unaided by the improved antenna. With the MI Wifi extender turned on, but with the antenna lying flat parallel to the ground, we only added about 50 more feet. When we turned the antenna up we again reached 250 feet.

Then we discovered something interesting. When we turned the Tello around facing the pilot the signal improved. So we were then able to fly it backward another 300 feet! So with the Tello facing the pilot and flying backward, it was able to go a whopping 550 feet (170 meters). That’s more than 5 times the range when flying forward unassisted. Apparently, the Tello was built for “dronies” (selfies pictures and videos taken from a drone).

MI WiFi Extender First Time Setup

I don’t want to bore you will all of the details – you already know how to install an app on your phone and follow simple instructions. The following tips are critical to make your setup easy the first time.

MI WiFi Tip 1 – Cool Your Tello

The Ryze Tello can overheat if you leave it powered on and don’t fly it. If setup takes you several minutes then you can put your Tello out of commission until it cools down. Save the hassle and put a fan on your Tello.

A fan will keep your Tello from overheating during a long setup process.

MI WiFi Tip 2 – Set Region as “Other”

Once you download and install the MI Home App you will be asked what your region is. This seems to only filter (and reduce) the number of available connected devices you can use the app for. This is a silly function and if you select “United States” you will find that the MI WiFi Extender does not make the list. Why? Who knows. Just use “other.” If you screw it up don’t worry, you can change your region in the settings

MI WiFi Tip 3 – Password is 00000000

Your Tello does not have a WiFi password, so just tell the MI Home app that the password is 00000000 (eight zeros). If you try and give your Tello a password in the Tello app you will turn your Tello into a brick. Don’t do that. If you do brick your Tello then just give the power button on your Tello a nice long hold – this resets the password back to where it should be – blank.

MI WiFi Tip 4 – Ignore the Error Message

If you have a blue light on the MI WiFi Extender then you are all set. The message you get at the end of setup is probably just telling you that your Tello has no internet connection. It’s all good! You are not using the Tello to update your Facebook profile.

So What Are You Waiting For?

The Tello is a great deal at under $100. The MI WiFi Extender is a slam dunk, it costs less than $15 and it works every time. If you need a battery then get one of those too. If you aren’t up for dealing with range extenders and you want better video then what you need is a DJI Mavic Air.
