US8315219 (Method for supporting mobility of a mobile
node in a multi-hop IP network and a network system
therefor): A method is provided for supporting mobility
of a Mobile Node (MN) in a multi-hop Internet Protocol
(IP) network, in which an MN that has moved from a
source Personal Area Network (PAN) to a target PAN,
sends a Router Solicitation (RS) message with an option
for requesting its profile to a gateway of the target PAN,
and receives a Router Advertisement (RA) message from
the gateway in response to the RS message. The RA
message includes a home prefix of the MN as the
requested profile. The method supports mobility of MNs,
enables unicast communication, and facilitates efficient
use of the network.

Broadcom's Wireless Internet
Connectivity for Embedded
Devices (WICED™)
platform enables WiFi
(802.11 b/g/n), Bluetooth,

US8849202 (Audio transfer using the Bluetooth Low
Energy standard): The described embodiments include a
system for communicating between electronic devices.
During operation, a receiving electronic device receives a
data channel protocol data unit (PDU) in a link layer of a
Bluetooth Low Energy (BTLE) protocol stack. The
receiving electronic device then reads a field in a header
of the data channel PDU to determine if the header
indicates that a payload of the data channel PDU contains
audio data. When the header indicates that the payload of
the data channel PDU contains audio data, the receiving
electronic device is configured to send the audio data
from the payload to an audio layer in the BTLE protocol
stack for processing.
US8451858 (Collision avoidance in multiple protocol
communication networks using a shared communication
medium ): A method for collision avoidance in multiple
protocol networks using a shared communication
medium begins by determining a first protocol probable
active time period. The method continues by determining
a first protocol probable inactive time period. The
method continues by generating a transmit blocking
indication based on the first protocol probable active
time period and the first protocol probable inactive time
period.

Bluetooth connectivity
US8594056 (Method and apparatus for dynamic and dual
antenna bluetooth (BT)/WLAN coexistence): An
apparatus and method are disclosed for effectively and
efficiently arbitrating concurrent usage between WLAN
and Bluetooth access technologies for co-located
wireless devices. A state level arbiter determines state
and relevant parameters of a WLAN module and of a
Bluetooth module of a wireless transceiver unit. The state
level arbiter uses the state and relevant parameters to
determine which access technology (WLAN or
Bluetooth) or combination of the access technologies
(WLAN or Bluetooth) will provide the best concurrent
performance for wireless transmissions at a given time
for specific Bluetooth states and WLAN states.

WiFi (802.11 b/g/n)
connectivity for the smart
home applications
Method and apparatus using sounding PPDUs to provide
range extension to IEEE 802.11n signals: A wireless
transmitter includes a stream parser for generating a
plurality of spatial streams from a digital signal and a
space time block coder (STBC) for mapping each of the
spatial streams to a plurality of space-time streams that
each include data and a preamble for estimating a
channel transfer function. The transmitter also includes a
spatial mapper for spatially expanding each of the space-
time streams by applying a spatial expansion matrix to
data and to first training symbols used in the preamble to
probe a channel experienced by the data and by applying
an extension matrix to second training symbols used in

the preamble to probe at least one additional dimension
of the channel to enable use of beamforming to achieve
range extension The spatial expansion matrix and the
extension matrix form an overall matrix that has at least
two orthogonal columns with different norms. The
wireless transmitter also includes an analog front end for
modulating the spatially expanded space-time streams
onto a wireless carrier.

The chipset comprises first and second processors. The
first processor reads audio source data from a storage
device and performs a first part of advanced audio
distribution profile (A2DP) source encoding. The second
processor is coupled to the first processor and performs a
second part of the advanced audio distribution profile
(A2DP) source encoding. The first and second processors
collectively act as a Bluetooth host.
