Abstract
Methods, systems, and apparatus for EM communications. One of the methods includes determining, at a first device, that a second device is present; initiating a half duplex communication with the second device; configuring communication with the second device including determining whether full duplex communication is available; in response to a determination that full duplex communication is not available, communicating with the second device in half duplex mode; and in response to a determination that full duplex communication is available, communication with the second device in full duplex mode.
Claims21
A method comprising:
- determining, at a first device, that a second device is present;
- initiating a half duplex communication with the second device;
- configuring communication with the second device including determining whether full duplex communication is available;
- in response to a determination that full duplex communication is not available, communicating with the second device in half duplex mode;
- and
- in response to a determination that full duplex communication is available, communication with the second device in full duplex mode.
A system comprising:
- a device having a communication module including a plurality of integrated circuit packages, wherein the communication module is configured to selectively operate in a half duplex communication mode or a full duplex communication mode when a contactless connection is made with another device, wherein half duplex communication mode uses only one of the plurality of integrated circuit packages to send and receive data, and wherein full duplex communication mode uses two or more of the integrated circuit packages, each of the integrated circuit packages operating as one of a transmitter or a receiver.
A method comprising:
- determining, at a first device, that a second device is present;
- initiating communication with the second device using a high speed communication mode;
- configuring communication with the second device including determining whether high speed communication is available;
- in response to a determination that high communication is not available, communicating with the second device in low speed communication mode, wherein the low speed communication mode may be full duplex or half duplex;
- and
- in response to a determination that high speed communication is available, communication with the second device in full duplex mode.
