Here’s an informational post for readers who may be considering a trip abroad where they want to stay in touch with work.
Last week, I stumbled across an article on BBC’s news site describing a new method of data transfer that will allow Internet speeds as fast as 400,000 Mbps (4 Gbps). I almost cried.
Do you know how fast your Internet connection is? If you’re reading this from the United States, you rank 8th in the world for Internet speeds, according to Akamai’s annual report. (South Korea is #1.) The USA average download speed, according to real-time user tests, is 17Mbps. At home, our cable provider supplied a 12 Mbps connection, sufficient to stream two Netflix movies simultaneously on two different computers. Alas, those days are over…
Our internet speeds on the road
As we’ve traveled these last 9 months, our data speeds have steadily decreased. I’ve included our connection speeds on our apartments as well as reported national averages:
|Country||Our download speed (Mbps)||National average (Mbps)|
Let me tell you, this has taken some getting used to! I will never take a good Internet connection for granted again. But we have gradually become accustomed to the slower connections, and I wonder what we’ll think when we get to a location with first-world internet access again…
On the positive side, if you’re thinking of telecommuting from abroad as we’re doing, I can report that it’s been very manageable, even with the slowest of connections. (Actually, the 500 kbps connection in Bostwana didn’t work so well, but I’ll share our workaround.) Here’s a breakdown (completely unscientific) of what we can/can’t do at the various speeds we’ve encountered:
|Speed||Works fine||So-So (works but is slow)||Forget it|
|500 kbps||Check email and basic Internet surfing||BBC News live stream||Connect to work’s VPN
Youtube videos? Ha!
|1.0 Mbps||Connect to work’s VPN||Skype (no video)|
|1.5 Mbps||Stream Internet radio stations (up to 64 kbps)||Youtube videos (if you don’t mind waiting 3-5 minutes for them to load)||Download a rental movie from Amazon.com in less than 7 hours|
|4 Mbps||Skype with video||Download a rental movie from Amazon.com while doing other Internet tasks (usually 3-4 hours)||Stream via Amazon or Netflix|
Our telecommuting requirements
We use a VPN (virtual private network) to access our work site and upload our research. For this, we don’t need a connection worthy of online gaming, but we do need enough bandwidth to connect to the VPN and then access another server to download/upload our assignments. I have found that we can get by with 1 Mbps.
Our Plan B
Our backup has been our 3G wireless modem. For about $70, we bought an unlocked mobile wifi (“mifi”) modem, the Huawei Technologies E5331, in Italy. It’s about the size of a credit card and we can connect up to 5 devices (laptops, netbook, iPods, etc.) to it wirelessly. Having an unlocked modem means that it works anywhere in the world on any provider’s network – all we need to do is buy a SIM card from a mobile phone store in each country for about $1 that (in theory) automatically connect to a local network. (We have had to request help from the tech support teams at two mobile phone companies. I’m baffled as to why my unlocked smartphone works just fine in each new country but the wifi modem sometimes takes some tweaking before it works…)
I call this method our backup because, although it easily meets our connection needs, it’s usually the most expensive option. For example, in South Africa we’ve found prices ranging from $20 – $45 for 2 GB of data. We use around 500 MB of data per day if we’re working, listening to online radio, checking email and bank accounts, and reading the news online.
How does 3G stack up?
From the northern reaches of Italy’s Dolomite mountains to the remote Kalahari Desert of Botswana, we’ve been pleasantly surprised at the availability of a reliable 3G cell phone signal. It’s allowed us to work on trains and in the car when needed. I’ve read that a 3G signal can run as high as 3.1 Mbps; I’ve found it to be more like 1 – 1.5 Mbps, at least here in the mountains of the Limpopo state of South Africa. If I want to get really crazy, I can walk 300 m up the mountain to where the cell tower peeks over the horizon, and Bam! 5 bars of solid 3G. It’s where I go to Skype with video, so long as the wind’s not too bad…
I can also report that 2G is not good; it simply isn’t fast enough to surf the internet at an acceptable speed, much less connect to our worksite’s VPN.
