BlipNet Mobility
BlipNet Mobility Service
The BlipNet mobility service enables seamless wireless network connectivity for Bluetooth
enabled devices. The mobility service automatically connects to subscribed devices when they
enter BlipNet coverage, and automatically hands over terminals from zone to zone as they
move around.
The BlipNet mobility service is based on the Bluetooth PAN profile which is basically a wireless
Ethernet bridge.
Mobility Zones
A mobility zone is a group of one or more BlipNodes defined in the BlipManager mobility
settings. All BlipNodes in a zone should be deployed in the same physical location. BlipNodes in
a zone can be defined as Discovery and Access Nodes, or Access only nodes.
Discovery Nodes
One BlipNode in each zone must be configured to periodically search for terminals. Due to the
fact that inquiry has a negative impact on data transfer rates, there is a trade-off between
discovering terminals quickly and ensuring a high data rate for connected devices. The interval
with which the BlipNode searches for terminals is configurable in the BlipManager mobility
settings; however, the default setting of 20 second intervals is recommended for most cases.
Adding Access Nodes to High Density Zones
If there is a high penetration of devices in a zone, or if there are high bandwidth requirements
for each device, more access nodes can be added to a zone. If multiple nodes are added to a
zone, the BlipNet Mobility Service does automatic load balancing between these nodes.
Supported Devices
Devices subscribed to the mobility service must support the Bluetooth PAN profile, and for the
hand-over functionality, Bluetooth scatternet support is required in the device. Examples of
devices supporting both PAN and scatternet is the HP iPAQ h1940, h2210 or similar, as well as
many Bluetooth PC dongles.
Older devices
Devices which do not support scatternet (such as older iPAQs and PC cards) can be
automatically connected by the system; however, when moving from zone to zone, the
connection will be disconnected briefly.
Pre-configuring BlipNodes
The BlipNodes which are to be used in the BlipNet Mobility Service must be pre-configured via
the BlipManager. A number of configuration options affect the Mobility Service:
PAN Service: The PAN service must be enabled in all BlipNodes in the Mobility Service.
