Wireless Networks Design (WiFi)

Wireless Networks Design

As infrastructure engineering design company, we are faced with new challenges coming from MOBILezation of everything. For example, more and more hardwired networks are superseded by  wireless ones even in commercial buildings and facilities. Same time Wireless solutions are still young and sometimes not working properly. Proper site survey and using right equipment is the key there to provide state of the art design. In Innovave, we also have a testing lab, where we have an ability to test equipment provided by manufacturers before implement it in our designs.

Wireless local area networks design includes next steps:

A. Site Survey Report: Prior to the WLAN design, Innovave prepares and submit a WLAN Site Survey Report. At a minimum, the report includes the following information:

1. Preliminary WLAN system architecture and design plans
2. Sketch of RF coverage and interference areas for Access Points
3. Options for access Point locations
4. Configuration mode (i.e., root, bridge, repeater)
5. Option Antenna types to be used per Access Point
6. Power provisioning requirements for the Access Points
7. Power output settings per Access Point
8. Connectors and cables to be used
9. Digital pictures of proposed locations for all Access Points and antennas

B. Design phase: Drawings:

1. Floor Plans indicating all components, raceways, terminal boxes, and cabling. Include radius of zone coverage of maximum signal strength for each access point installed.
2. Riser diagram indicating all connections in a manner following the floor plan layout.
3. Cabling diagram indicating the designed routing and number of cables in specific raceways or conduits, from the main data sources connecting to other sub-panels, modules, or devices.
4. Installation and coordination drawings for items in other sections.
5. Access Points and antennas with dimensions, WLAN topology maps, location designations, and instrument wiring diagrams. Indicate required interfaces with equipment provided in other sections.

D. Integration plan that details the implementation strategy to complete the WLAN system.
