Environment Verification & Validation; Compliance With (R 2.0 Offer); Pre Install Vowlan Radio Coverage Audit (Site Survey) - Alcatel-Lucent OmniPCX Enterprise R7.1 Manual

Voice over WLAN Mobile IP Touch Design Guide R2.0
4. 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 2.0 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. Please ensure that the proposed solution
does not violate the list of restrictions provided in section

4.2. Pre Install VoWLAN Radio Coverage Audit (Site Survey)

It s recognized that in many situations, a customer may be unwilling or unable to perform a wireless
audit before the establishment of budgetary costs (RFP/RFQ.) Regardless of whether or not predictive
tools were used to define a "budgetary" topology design, a Radio Coverage Audit (also known as a Site
Survey) is mandatory for all MIPT VoWLAN solutions prior to installation. Voice quality and coverage
continuity can not be guaranteed without this compulsory environmental evaluation.
In ideal situations, this audit would be performed as the first step towards building a VoWLAN solution.
The results of the audit could be used to strategically identify ideal locations for Access Points to
maximize coverage and minimize radio spectrum conflict. By working backwards from the Access Points,
we could easily see where best to place and how best to size Wireless Switches and/or Wireless
Appliances.
VoWLAN Radio Coverage Audits are very specific in that they focus on the requirements of 802.11b based
wireless clients. Being small, handheld, battery operated devices; Mobile IP Touch terminals possess
unique radio sensitivities. Where a typical Wi-Fi enabled PC could find the ability to maintain a useful
connection with a signal as weak as -80dBm, MIPT terminals lose reliable communications capabilities
beyond (approximately) -65dBm. It is for this reason that typical Wi-Fi surveys, as well surveys for other
digital wireless technologies, can not be used for VoWLAN solutions. Again: A VoWLAN Radio Coverage
Audit is mandatory for all solutions prior to installation.
Alcatel-Lucent's OmniAccess platform family can be used to support data as well as voice. For solutions
that propose both voice and data coverage, it is important to distinguish between the needs of the voice
and data elements. If voice and data are to share 802.11b Access Points, bandwidth consumption and
client saturation need to be incorporated into the overall audit results. If the data will utilize 802.11a
Access Points, a completely different wireless audit may be required.
The specificity of VoWLAN audits requires a certain level of solution specific training and knowledge. For
the benefit of Alcatel-Lucent customers and business partners, Alcatel-Lucent's Professional Services
organization can provide VoWLAN and WLAN Radio Coverage Audits at a competitive price. For more
