The cellular telecommunications market not too long ago announced a intriguing advancement: the integration of a WiFi hotspot inside a standard GSM SIM card. The complete WiFi hotspot including antenna have been built-in into the very small 25x15x1mm SIM card. When inserted into a regular GSM telephone, the SIM card uses SIMtoolkit to obtain the data bearers (like GPRS, EDGE, HSDPA, and many others) offered on the cellphone. Consequently generating a WiFi hotspot around the cellphone. In my experience, the range of these kinds of a configuration would be constrained (metres rather than a hundred metres), but this technologies provides the likely of accessing the world wide web from your WiFi enabled netbook utilizing a regular cellular mobile phone.
This engineering was initially conceived by Telenor, who were at the time investigating options to find cell phones with a large degree of resolution within buildings. They used a WiFi access node built-in inside a SIM card to report again the WiFi cells in selection, that’s why figuring out the mobile phone’s approximate placement. This in my view is an revolutionary answer to an age previous dilemma. Telefonica, doing work with the SIM vendor Sagem Orga (Morpho) just lately introduced the SIMfi, as a professional item.
The question which remains unanswered is, “is this technology for technologies sake?” Or is there a true commercial design fundamental this technological innovation. There are a variety of prospective programs, for illustration, effectively using the WiFi website link to replace a cable (tethered connectivity) to allow laptops to entry the internet. For precise in-constructing spot. Or, for the creation of millions of shifting WiFi hotspots to offer a information network backhauled making use of the cellular community.

In my knowledge, mobile network operators consider to go traffic off their mobile networks (like EDGE or HSDPA), on to fastened WiFi networks anywhere attainable. This is to alleviate Quality of Provider troubles that they are presently encountering. Consequently, it’s most very likely that any embedded WiFi unit inside a SIM will be employed as an obtain node not a HotStop. Other than by govt mandate, there are few extremely productive, paid out for, place apps.
Update 2014: it would seem that the integration of WiFi into a SD memory card has verified to be a much much more common selection between consumers. Spot update supported by WiFi or GPS inside a handset unit has turn out to be a extremely well-known characteristic. Though many progressive place conscious purposes have emerged, and numerous have become successful, cellular operators are nevertheless in research of location purposes that represent a content income stream.
