Mobile Phone SIM Cards With Integrated WiFi Hotspots, Applications and Commercial Models

The cellular telecommunications industry lately introduced a interesting enhancement: the integration of a WiFi hotspot inside of a regular GSM SIM card. The overall WiFi hotspot which include antenna have been integrated into the tiny 25x15x1mm SIM card. When inserted into a usual GSM cellphone, the SIM card employs SIMtoolkit to entry the information bearers (like GPRS, EDGE, HSDPA, etcetera) obtainable on the cell phone. That’s why making a WiFi hotspot close to the phone. In my practical experience, the selection of this kind of a configuration would be limited (metres somewhat than a hundred metres), but this engineering delivers the likely of accessing the world wide web from your WiFi enabled netbook making use of a common mobile cell phone.

This engineering was at first conceived by Telenor, who ended up at the time investigating solutions to find cell telephones with a significant diploma of resolution inside buildings. They employed a WiFi obtain node integrated within a SIM card to report back again the WiFi cells in array, hence analyzing the cellular phone’s approximate place. This in my viewpoint is an revolutionary answer to an age previous dilemma. Telefonica, working with the SIM seller Sagem Orga (Morpho) lately launched the SIMfi, as a commercial solution.

The issue which remains unanswered is, “is this know-how for technologies sake?” Or is there a true professional product fundamental this technological innovation. There are a variety of potential purposes, for illustration, effectively utilizing the WiFi link to swap a cable (tethered connectivity) to empower laptops to access the internet. For accurate in-setting up location. Or, for the creation of millions of moving WiFi hotspots to give a facts network backhauled making use of the cell community.

In my experience, mobile network operators test to go targeted visitors off their mobile networks (like EDGE or HSDPA), on to fastened WiFi networks where ever feasible. This is to reduce Good quality of Services difficulties that they are at this time encountering. Consequently, it truly is most likely that any embedded WiFi system within a SIM will be used as an obtain node not a HotStop. Other than by government mandate, there are handful of hugely profitable, paid out for, place purposes.

Update 2014: it seems that the integration of WiFi into a SD memory card has verified to be a a great deal a lot more well known possibility amongst buyers. Site update supported by WiFi or GPS within a handset product has turn out to be a very preferred feature. Whilst quite a few modern place aware purposes have emerged, and several have come to be thriving, cell operators are even now in research of locale applications that stand for a materials profits stream.
