Soy ingeniero en sistemas, con una posgrado en telecomunicaciones, podria apoyarte en el proyecto que comentas, te pronpongo guiarte y asesorarte en el proyecto que tienes pensado realizar, los perimetros virtuales como comentas se realizan mas bien por medio de coordenadas geograficas que emiten los telefonos, lo que pretendes realizar es un tanto mas complejo tendrias que montar practicamente una celula de celular tipo proveedor de servicios para que todos los celulares que esten en el alcance de tu antena al emitiar una ack de asociación la antena les pida su numero y les envie mensajes, pero es un tanto mas complejo, lo que se hace actualmente, creo que deberiamos de platicar primero que es lo que esperas de tu proyecto a detalle para elegir una buena solucion saludos
