Could Dualband GSM GPS Trackers End Your Business?

Author : Rose Li

One of the fastest growing market for GPS tracking devices these days is the one for GPS trackers equipped with SOS calling features that make use of existing GSM networks.

Concerned parents and caregivers are clamoring for these specialized GPS tracking devices that can be just as much of a two-way communication device as they are a tracking tool.

Their growing popularity and high conceived value makes them perfect as items to be listed on eBay or on your own e-Commerce website.

However, the same GSM frequency problems which plague unlocked cell phone sellers can also strike these devices.

But before we look at that, and how to avoid these scenarios lets take a look at exactly what the GPS tracker with SOS calling is and why it has gained such popularity.

** Why GPS With SOS Calling? **

GPS trackers with SOS calling functionality are compact and light gadgets that can be worn like a necklace around the neck or tossed inside your jean pockets without causing any discomfort on the part of the wearer.

They keep track of the location of the wearer and can transmit that back to the parent or caregiver but also act as a two-way communication device.

Parents who are concerned about their children's welfare think giving these devices to their children is preferable to setting strict rules about when the child has to be home and where the child is able to go as it gives them some sense of freedom – up to some extent.

GPS trackers with SOS calling can send out SMS signals or email if your kid goes outside the virtual boundary you have set.

And if they get lost or in get themselves in danger they can contact you immediately through the device which you can also use as a homing beacon to get to their exact location.

It is for this exact reason that caregivers and families taking care of the elderly or people with disabilities may find these GPS trackers useful.

** GSM Frequencies And How Too Few Can Foul Understanding GSM Frequencies and How is Can Affect Your GPS Tracker Business **

Something that sellers of unbranded, unlocked cell phones sourced internationally have learnt the hard way is that all cell phones don't work in all regions.

There are four main GSM frequencies that work in some par of the world 850MHz, 900MHz, 1800MHz and 2100MHz. 900MHz and 1800MHz works in Europe, Asia, Oceania and Africa/, 850MHz and 2100MHz works in North and South America.

GSM devices tend to fall into one of three categories.

* Dual band devices which only work in the Americas or only work in the rest of the world
* Tri-band devices that kind of work in both places
* Quadband devices that work in all corners of the world

A dualband device for the US is quite different for another dualband device intended for international use and if a customer from the US unwittingly buys a dual band GPS tracker for use in their own country they have just effectively purchased a paperweight.

Before posting any GPS tracking device for sale on eBay or on your website, be sure that you clearly indicate their operating frequencies. Throw in a disclaimer that so and so device would work only in the US or otherwise. Be clear about it – and save your own skin.
