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 refrigerator manufacturer company was predicted to have 7 Motorola AP300’s with 2 5Ghz Omni Antenna’s for each AP were placed throughout the warehouse. Each AP300 was placed roughly 33′ 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. Yellow represents channel 1, Blue represents channel 6, and Red for channel 11. Also the X,Y coordinates were added next to the AP to accurately place each AP throughout the warehouse.
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 refrigerator manufacturer company LanPlanner predicted the 7 AP’s would cover the warehouse from 24Mbs to 54Mbs of coverage. In the colored heat map drawing of the warehouse, 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.
