Selecting a BSAP Installation Location
BlueSecure™ Access Point 1800 Installation Guide 7
The BSAP also needs the IP address of the home BSC to which it will connect and
from which it will obtain its software image and configuration. Again, this is not
needed if the BSAP is on the managed side getting a relayed IP address from the
BSC. You can provide the home BSC IP address to a BSAP using one of the
following methods:
• DHCP Server Option 43 - You can manually configure the DHCP server
on your network to send BSC IP addresses to BSAPs using DHCP vendor-
specific option 43.
In DHCP requests sent from the BSAP, the BSAP uses option 60 Vendor class
identifier with a value of BlueSecure.AP1500 to identify itself to the DHCP
server (Note that all BSAPs —1500,1540,1800 —identify as AP1500 for
option 43).
Refer to the documentation supplied with your DHCP server when configuring
vendor-specific option 43
• DNS Server Configuration - BSAPs are factory configured with
apdiscovery as the DNS hostname. You can configure a DNS server on
your network with an entry for apdiscovery with the home BSC Controller IP
address as the resolution.
To configure this, add a NAME record to the DNS server for apdiscovery (at
the domain server that the BAP will receive). Point this name to one or more
BSC IP addresses (managed, protected or VLAN depending on the network
configuration).
So for example, if there are two BSCs (192.168.100.23 and
192.168.100.28), and the domain is customer.com, add two NAME records
to customer.com, for the name apdiscovery.customer.com. One should
resolve to 192.168.100.23 and one to 192.168.100.28. PTR (i.e., pointer)
records are not needed for this portion of discovery.
Selecting a BSAP Installation Location
BlueSecure Access Points should be positioned for maximum throughput and
range between other BSAPs and wireless client devices. Normally, you should
locate the BSAP on the ceiling away from obstructions.
Range and performance are dictated by the distance between the BSAP and
client radios, and by obstacles that may be present in a specific building or office
environment. The following positioning guidelines are suggested:
• Document all the BSAPs and client devices you wish to include in your
wireless network. Record the MAC address, serial number, and placement of
each BSAP.
• Wired LAN and power connections must be available for each BSAP at the
desired installation location. If a power outlet is not available near the access
point, mid-span power inserters are recommended.
• If building blueprints or floor plans are available, use them to define potential
client device locations and likely roaming areas.
• Identify possible obstacles or sources of interference that could affect signal
strength (for example, walls, metal objects).
