Deploying the Wireless Network
Microsoft s deployment of wireless access occurred in four phases, as discussed in the following sections.
Phase 1: Pre-installation
Phase 2: Installation
Phase 3: Delivery
Phase 4: Rollout to Microsoft users
Phase 1: Pre-Installation
Pre-installation involved the following steps:
Developing a wireless AP location plan based on design guidelines in which 95 percent of the installations require no specialized antennas.
Performing field-verification of proposed wireless AP locations to check for physical interference.
Presenting the final locations to a Microsoft OTG designer for approval prior to starting installation.
Phase 2: Installation
Physical installation of the wireless APs involved the following steps:
Enclosing wireless APs and antennas within plenum-rated enclosures to meet fire safety code requirements.
Configuring central, low-voltage power supply on backup power using uninterruptible power supplies.
Building out RADIUS infrastructure.
Phase 3: Delivery
Delivery involved the following steps:
Spot-checking wireless AP installation for conformance with commissioning checklist.
Verifying radio frequency (RF) coverage and network connectivity of each wireless AP.
Delivering as-built documents, reflecting the final placement of each wireless AP.
Phase 4: Rollout to Microsoft Users
The rollout to Microsoft users involved the following steps:
Creating a Cryptographic API Component Object Model (CAPICOM) script to install certificates.
Creating a Web site to host information about instructions, updated drivers, and the CAPICOM script.
Telling users of the Web site how to obtain wireless access.
To obtain the computer and user certificates required for wireless connectivity to the Microsoft corporate wireless network, the computer, typically a wireless laptop computer, must first connect to the Microsoft Corpnet using an Ethernet connection.
