## Abstract

Time-frequency coding in a multi-band ultra-wideband system is generally described. In this regard a hopping code agent is presented to select a frequency hopping code for encoding and decoding from a set of predetermined FHC's for communicating with other devices in a multi-band ultra-wideband (MB-UWB) network, wherein the FHC defines a sequence of two or more pulses over two or more frequencies and wherein the FHC's include a time slot that contains no transmission. Other embodiments are also disclosed and claimed.

## Claims

### Claim 1

An electronic appliance, comprising:
one or more dipole antenna(e);
one or more transceiver(s), coupled with the one or more dipole antenna(e), to communicate with other devices; and
a hopping code engine to select a frequency hopping code (FHC) from a set of predetermined FHC's for communicating with other devices in a multi-band ultra-wideband (MB-UWB) network, wherein the FHC is selected based on being able to decode a beacon signal, wherein the FHC defines a sequence of two or more pulses over two or more frequencies and wherein the FHC's include a time slot that contains no transmission.

### Claim 2 (depends on 1)

The electronic appliance of claim 1, wherein the hopping code engine to select a frequency hopping code (FHC) from a set of predetermined FHC's for communicating with other devices in a multi-band ultra-wideband (MB-UWB) network comprises:
the hopping code engine to select a frequency hopping code (FHC) from a set of predetermined FHC's for communicating with other devices in an Institute of Electrical and Electronics Engineers (IEEE) 802.15.3 network.

### Claim 3 (depends on 1)

The electronic appliance of claim 1, further comprising: the hopping code engine to encode a communication to transmit using the selected FHC.

### Claim 4 (depends on 1)

The electronic appliance of claim 1, further comprising:
the hopping code engine to decode a communication received using the selected FHC.

### Claim 5

An apparatus, comprising:
one or more dipole antenna(e);
one or more transceiver(s), coupled with the dipole antenna(e), to communicate with other devices; and
control logic coupled with the transceiver(s), the control logic to select a frequency hopping code (FHC) from a set of predetermined FHC's for communicating with other devices in a multi-band ultra-wideband (MB-UWB) network, wherein the FHC is selected based on being able to decode a beacon signal, wherein the FHC defines a sequence of two or more pulses over two or more frequencies and wherein the FHC's include a time slot that contains no transmission.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the control logic to select a frequency hopping code (FHC) from a set of predetermined FHC's for communicating with other devices in a multi-band ultra-wideband (MB-UWB) network comprises:
control logic to select a frequency hopping code (FHC) from a set of predetermined FHC's for communicating with other devices in an Institute of Electrical and Electronics Engineers (IEEE) 802.15.3 network.

### Claim 7 (depends on 5)

The apparatus of claim 5, further comprising:
control logic to encode a communication to transmit using the selected FHC.

### Claim 8 (depends on 5)

The apparatus of claim 5, further comprising:
control logic to decode a communication received using the selected FHC.
