Q7. |
How
do the BreadCrumbs communicate? |

|
| |
|
|
|
| |

Can
you secure BreadCrumb®
communications? |
|
| |
A8. |
Yes.
There are several ways to secure communications
between BreadCrumbs. Any layer 2 or
layer 3 encryption products can be
used with the BreadCrumbs. |
|
| |
|
|
|
| |

module, can you integrate it to work
over the BreadCrumb®
network? |
|
| |
A9. |
Yes,
please contact us with your specific
requirements. |
|
| |
|
|
|
| |

|
| |
Q11. |
Do
clients attach in an ad-hoc mode or
in infrastructure mode? |
|
| |
A11. |
Infrastructure
mode. |
|
| |
|
|
|
| |
Q12. |
How
many times can you hop through a repeating
BreadCrumb® before
you notice significant network latency? |
|
| |
A12. |
Each
BreadCrumb® adds
approximately 2ms-10ms per hop; performance
is dependant upon type and magnitude
of traffic. |
|
| |
|
|
|
| |
Q13. |
What
uplink devices do you support? |
|
| |
A13. |
We
can bridge or gateway to any type
of uplink with an Ethernet interface.
We have interfaces into Inmarsat terminals,
Iridium phones, and various Data link
connections through an Ethernet media
converter. (T1/T3,OC3,etc.) |
|
| |
|
|
|
| |
Q14. |
Can
the BreadCrumb®
network act as a bridge between two
wired networks? |
|
| |
A14. |
Yes. |
|
| |
|
|
|
| |
Q15. |
Can
the BreadCrumb®
multi-home between two uplink points? |
|
| |
A15. |
At
this point not automatically, but
there is a way to do this manually
using external DHCP servers and settings.BreadCrumb®
Operations. |
|
| |
|
|
|
| |
Q16. |
How
do you connect BreadCrumbs to an existing
network? |
|
| |
A16. |
ReachBack
is achieved by several different ways.
You can connect the Ethernet port
to the uplink, and have the BreadCrumb®
DHCP and address from the uplink in
automatic mode. You can also select
bridge mode if you wish to extend
the existing wired network over the
wireless BreadCrumb®
network, or you can select gateway
mode to segment the BreadCrumb network
from your uplink network. |
|
| |
|
|
|
| |
Q17. |
Will
BreadCrumbs allow DHCP pass through? |
|
| |
A17. |
Yes,
in bridge mode. |
|
| |
|
|
|
| |
Q18. |
How
do I disable the DHCP server on the
BreadCrumbs? |
|
| |
A18. |
You
select a BreadCrumb®,
right-click, select properties, and
disable it in the properties control
panel. |
|
| |
|
|
|
| |
Q19. |
What
IP space does a BreadCrumb®
network use? |
|
| |
A19. |
The
BreadCrumbs use 10.x.x.x/8 for inter-BreadCrumb®
communication and administration. |
|
| |
|
|
|
| |
Q20. |
Can
the BreadCrumbs provide DHCP pools
for the devices on the BreadCrumb®
network? |
|
| |
A20. |
Yes.
The standard pools are setup as:
10.x.x.1 –
9 are reserved for internal BreadCrumb®
use
10.x.x.10 – 200 are dynamically
assigned by internal BreadCrumb®
DHCP server
10.x.x.201 –
254 are available for static assignment |
|
| |
|
|
|
| |
Q21. |
Can
you operate separate BreadCrumb®
networks concurrently in the
same geographic area? |
|
| |
A21. |
Yes,
you can! The safest way to do this
is to have unique SSID's and WEP keys
between the separate networks. This
ensures clients from disparate networks
will not associate to each other's
network. BCAdmin Operations |
|
| |
|
|
|
| |
Q22. |
What
is BCAdmin and why do I need it? |
|
| |
A22. |
You
need it to setup and configure the
network. You can also use it to monitor
the network but it is not required
once the network is operational. BCAdmin
is NOT required for a network to operate. |
|
| |
|
|
|
| |
Q23. |
Why
is BCAdmin screen Red and empty? |
|
| |
A23. |
The
most common reason is you do not have
a 10.x.x.x address to administrate
with the BreadCrumbs. |
|
| |
|
|
|
| |
Q24. |
Why
is the BCAdmin screen Black and empty? |
|
| |
A24. |
BCAdmin
is unable to communicate with any
BreadCrumbs. However, personal firewall
applications may be preventing BCAdmin
from communicating with the BreadCrumbs.
Windows XP Service Pack 2 also blocks
communications with BreadCrumbs by
default. |
|
| |
|
|
|
| |
Q25. |
Why
are the BreadCrumbs going red? |
|
| |
A25. |
This
means that BCAdmin has been unable
to communicate with that BreadCrumb®
for 60 seconds. This could be due
to several factors: Radio path obstructions,
dead or failing BreadCrumb
battery, or a rebooting BreadCrumb.
Security settings may also cause a
breakdown in communication. |
|
| |
|
|
|
| |
Q26. |
What
are the minimum specs to run BCAdmin? |
|
| |
A26. |
Required
Specifications:
CPU: PIII 500 MHz
(1 GHz or higher recommended)
RAM: 256 MB
Operating System:
Windows 2000 or higher, Linux Java
