3. Design Process for VoWLAN

3.1. Pre Sale Data Collection

In order to prepare an Alcatel-Lucent VoWLAN solution, several pieces of documentation must be sourced
from the customer. The accuracy of a final system proposal is directly related, in most cases, to the
amount and quality of information collected prior to initiating design formulation.

3.1.1. Physical Diagram (to include existing wireless technologies)

A clear understanding of the customer's physical network topology is essential in order to properly
determine the possible future locations and integration points of VoWLAN support elements. This
physical diagram should be as complete as possible and include information related to all existing
customer infrastructure (Data Wi-Fi, LAN, MAN, closet switching platforms (to include power feeding
abilities), core routing platforms, copper and fiber patching facilities (termination types).) Again, an
accurate MIPT VoWLAN solution can not be developed without this information.
The physical diagram is responsible for helping the design engineer in gauging a number of placement
and connectivity options from the number of locations where OmniAccess Wireless Switch/Appliance
platforms can be housed, to the type of physical connectors needed on the fiber patch cords to connect
them to the network. To meet this requirement, the physical diagram must contain as much detail as
possible.
This diagram should also detail cable-plant distances and the ability of existing data network switches to
support IEEE 802.3af power in sufficient quantity for the proposed solution.
Of a much more complex nature is the presence and status of existing wireless technology. The Physical
diagram should detail, in as much detail as possible, the presence of existing or proposed Bluetooth, Wi-
Fi, microwave technology, high-gain or industrial radio transmitters, DECT/PWT technologies and other
interference or radio spectrum competitors.
