I hope you’re well and having a good summer?
I often get asked “Where in the World does Vismo work?“. The answer is “Anywhere there is mobile data”.
Vismo works on a smartphone by using mobile data (GPRS) to send back its location fixes to the Secure Website. If there is no mobile data coverage Vismo can’t send back the location information and as a consequence displaying a travellers position could be delayed for a considerable time. In these areas I would always recommend the use of a satellite phone with GPS or satellite tracker. The options Vismo has for satellite tracking are shown on our product page www.vismo.com/products. All solutions are available for purchase or rent through Vismo.
How can you tell where there is good data coverage around the world? I thought it might be helpful to share a really useful site I stumbled across that shows mobile coverage across the globe.
In the example below I’ve picked Abidjan in the Ivory Coast.
Clearly you can see good coverage in Abidjan, and then patches of coverage elsewhere. In areas without data coverage Vismo would continue taking fixes on a mobile device, but would have limited opportunity to send those fixes back to be displayed on the Vismo Secure Website.
The site used for viewing data coverage is www.opensignal.com
OpenSignal.com is a company that specialises in wireless coverage mapping. The company crowdsources data on carrier signal quality from users who have its consumer mobile application installed.
