How will the billion people who still useolder 2 G cellphonesuse them to pay up for commodity , just like mass with smartphones fit out withnear - field of study communications(NFC ) wireless liaison ? One response is to place a tiny 2 G groundwork station at the item of sale so that those old non - NFC phones can also make a short - kitchen stove transaction firmly .
So enjoin Cambridge Consultants Limited , a UK - base engineering development house which exhibit what it claim is the world ’s little cell base station system at its lab on 8 November . CalledSidewinder , “ it ’s an entire GSM meshing ladder on one circuit circuit card ” , say Monty Barlow , head of CCL ’s signal processing chemical group . “ It has everything a cell tower would need to run eight concurrent 2 G cellphone calls . That normally needs racks and racks of equipment . ”
Crucially , the electric circuit ’s power can be wrench down to give it a low chain of mountains of a metre or so . So any proceedings contract – extracting cash blame up on a SIM card , say – are not being beam to a upstage cell tower where they may be intercepted by attackers en itinerary . “ We can detect the propinquity of those honest-to-goodness telephone set and deliver a phone number of services to them securely , ” says Barlow .
In CCL ’s demo , the lap was shew move calls on three 2 G phones simultaneously . The organization ’s secret is the fact that its cellphone data formatting and power is entirely defined in package . That means it has the capableness , with a software update , to become a extremely portable 3 grand base post , or awhite - blank space radio , that could allow the fast setting - up of other types of advert - hoc net – such as after earthquake or uttermost atmospheric condition outcome when other mesh may be down .
However , cellphone oftenness are an expensive resourcefulness for which internet ante up billions of buck , so CCL can not use them at will . The companionship is hoping to hit deals with internet operators that might add Sidewinder services to their networks .
