CIRCUITS AND SYSTEMS TO EXCHANGE SUBSCRIBER IDENTITY MODULE (SIM) INFORMATION OVER A DISTANCE

摘要

A circuitry and a wireless communication system for carrying SIM card data over a distance. The wireless communication system comprises a first network node and a second network node. A SIM card can be placed in the first network node. SIM card data can be retrieved from or written to the SIM card by a second node via a cable. Other data communications between the first network node and the second network node is carried by another cable. In one variant, the other capable also carry electricity from one of the network node to the other network node. In one variant, the circuitry for carrying SIM card data comprises a plurality of buffers, resistors, capacitors and bi-directional level shifters.
