Figure 10 Predictive Method: AP Calculation
Example Results:
Area 1
=> Quantity of AP = (31 x 31)/250 = 3.84 =>
4 AP (rounded up to next highest whole number)
Area 2
=> Quantity of AP = (31 x 96)/250 = 11.9 =>
12 AP

Predictive Tool Coverage Planning
In the interest of easing predictive planning for large sites, or sites not yet fully constructed, several
predictive coverage planning tools are available. These tools focus almost exclusively on the service
requirements of 802.11 data clients with typical power and sensitivity specifications. It is for this reason that
the use of predictive planning tools is not currently recommended by Alcatel. Even in the case of Alcatel's
predictive planning tool, the unique operational characteristics of MIPT handsets can not be taken into full
consideration, resulting in often flawed and under-engineered proposals. When the use of such tools is
absolutely mandatory, it is recommended that a coverage plan of 160% or better be used in order to ensure
proper plan overlap at the desired -65 dB level. It is assumed that future versions of predictive coverage
planning tools will be more accurate, and capable of calculating plans based on VoWLAN characteristics.

Environment Verification & Validation
After collecting information on the customer data networking environment from both a logical and physical
perspective, and evaluating the customer voice communications needs; it becomes important to verify and
validate the collected information. These operations are not meant to be insulting to a customer or business
partner, nor are these practices meant to be “revenue generation” tactics. The processes outlined below are
incredibly important steps required to ensure customer satisfaction and to provide for baseline references for
support contracts and service level agreements.
4.1.
Compliance with (R 1.1.1 Offer)
As previously stated, the MIPT VoWLAN solution offer is being delivered in a multi-stage format. Proposed
designs must be built with a clear knowledge and respect for the present offer restrictions. For example,
networking criteria should be carefully analyzed. The MIPT R1.1.1 solution offers no support for multi-site
communication flows (MIPT handsets are not permitted to communicate with MIPT handsets on another
network node.)
Please ensure that the proposed solution does not violate the list of restrictions provided in section 3.1.4.2
above.
