The AutoCAD drawing was sent from the healthcare company to be formatted in LanPlanner. Customer gave the required LanPlanner details of the drawing. Which included, the height of the building, the length of the building (only required if drawing is not scale), and obstruction information. Customer requested only certian area of the facilty be covered. The area that is to be coverd is 12 feet tall roughly 300′ in length and roughly 320′ in width. The building consisted of open areas and one area with metal racking.

After the the AutoCAD drawing was inserted into LanPlanner software, LanPlanner will format the building. Formatting the building is a crucial part in the site survey process. In order to accurately predict and measure the RF infrastructure the format process must be accurate. The format process consist of telling LanPlanner from the original drawing what type of obstruction is in the building and what the obstruction is made of and the height of the obstruction.

After the format process, Access Points/Ports can be placed throughout the warehouse. The healthcare company was predicted to have 6 Motorola AP300’s with internal antennas to be placed through the required coverage area. Each AP300 was placed roughly 8′ from the ceiling. Each AP300 color represents a channel. For the least amount of channel interference for 802.11b/g, channels 1, 6, & 11 are to be used. Black represents channel 1, Yellow represents channel 6, and Red for channel 11.

With the AP’s placed then LanPlanner can predict the RSSI(Received Signal Strength Indication), SNR (Signal to Noise Ratio), Channels, and the throughput. For this healthcare company LanPlanner predicted the 6 AP’s would cover the requested areas. In the colored heat map drawing, each color represents a different amount of RSSI or throughput. RED is a -50dBm(dBm is the power ratio in decibels) or can represent any where from 48Mbs to 54Mbs of throughput. YELLOW is a -60dBm or can also represent anywhere from 36Mbs to 48Mbs of throughput. GREEN is a -70dBm or also represented anywhere from 24Mbs to 36Mbs of throughput. It is important to note that if some areas of the prediction does not show a ‘good’ coverage grid, does not mean that the measured coverage will be the same. The predictions are based on what specifications and obstruction information was given by the customer.
