WIFI Design

One of the key factors that MELE uses to ensure a successful wireless Local Area Network (LAN) deployment is a site survey. Before deploying or expanding your wireless LAN, we emphasize understanding the needs of users in their current environment. A site survey can identify the appropriate technologies to apply; obstacles to avoid, eliminate, or work around; coverage patterns to adopt; and amount of capacity needed. Your site survey should yield a network design document that describes the location of each access point, its coverage area, and the 802.11 a, b, or g channel selections for the access point. The network design document should also provide a complete Bill of Materials (BoM), indicating the WLAN equipment and supplies, infrastructure equipment and supplies to provide Power over Ethernet (PoE), and additional switch ports; and should include a vendor description of each WLAN component.

MELE uses a state-of-the-art technology to design cost-efficient robust wireless networks. We offer a turnkey solution from design, to selling the product, to installation and configuration.

We generate a comprehensive report that includes the final floor plan and:

  • Recommend the number of access points needed
  • Recommend location co-ordinates for access points
  • Name/MAC address of access points
  • Channel/SSID allocated
  • Height of the access point/antenna above floor level
  • Type of the antenna and  its specifications

Using automated Wi-Fi surveying and planning tools, our designers can electronically pre-design the WLAN before work begins. MELE imports the blueprint into the application and indicates where to place Access Points (AP’s), and how many are needed based on stated wireless goals and the type of Wi-Fi equipment selected.  To create the optimal Wi-Fi design, network designers and IT management should determine:

  • Where in the building wireless connectivity is desired;
  • Whether to provide users with near-ubiquitous coverage throughout the building, or whether coverage in key common areas will suffice; and
  • Who will have access to the network - and where they are likely to roam throughout the building.

A major network design decision concerns the Wireless Local Area Network (WLAN) applications to be supported. Wireless networks supporting Voice over IP (VoIP) typically require denser AP deployment than those that simply provide wireless data access. This deployment is needed since data networking is far more tolerant of packet loss, delivery delays and jitter than voice, which requires stable, ubiquitous coverage and minimum delays when connections are handed off from AP to AP as a user roams.

For data access, installing an AP in public areas, such as meeting rooms, cafeteria and lobby, might be sufficient for some organizations. However, consistent voice and location service support will require coverage nearly everywhere. That expanse of coverage means more APs and more cabling runs to more places. The same density consideration applies to data connections in areas where large groups of people congregate to use the network simultaneously. We consider all of these factors up front to avert wireless coverage problems later on.

All of this will assist in making the correct purchase of equipment more cost effective.
