Is MDS/MDG Specific To Blackberries?
Not quite. All modern cellphones with access to the Internet, require a gateway of some kind. You may have heard of these in different naming conventions such as GGSN, APN, MDG, etc. In simple terms, they essentially make connections possible between a carrier network and an external network, such as the Internet on your mobile device (or even just a simple connection to a BES server). If you have heard of GGSN (APN) on a cellphone, then that’s a network component similiar to MDG. More information about various gateway services is provided on this SourceO2 page and on this Motorola iDEN page. Only MDS is Blackberry specific, while MDG and GGSN (APN) is not Blackberry specific. In fact, MDS still uses MDG in order to connect between a Blackberry and a BES server, and then from there, mobile Internet connections are made through your company’s Internet connection.
