Phase I – VAPs Locations Planning
The MobileAccessVE Dual-Band solution supports up to 12 VCUs connected to the Master VCU, each capable of
supporting up to 12 VAPs.
Plan your VAP placement according to environments that are most compatible with your site:
Standard Environment
1
Open Floor Plant
Dense Environment
2
Place VAPs:
CELL/PCS:
67 feet (20.5 m) apart
Maximum of 33 feet (10 m)
from the outer building walls
(so mobile users have line-of-
sight to VAPs).
EGSM/UMTS or DCS/UMTS:
57.5 feet (17.5 m) apart
Maximum of 29 feet (9 m) from
the outer building walls (so
mobile users have line-of-sight
to VAPs).
Place VAPs:
CELL/PCS:
90 feet (27 m) apart
Maximum of 45 feet (13.5 m)
from the outer building walls
(so mobile users have line-of-
sight to VAPs).
EGSM/UMTS or DCS/UMTS:
67 feet (20.5 m) apart
Maximum of 33 feet (10 m)
from the outer building walls
(so mobile users have line-of-
sight to VAPs).
Place VAPs:
CELL/PCS:
64 feet (19.5 m) apart
Maximum of 33 feet (10 m)
from the outer building walls
(so mobile users have line-of-
sight to VAPs).
EGSM/UMTS or DCS/UMTS:
45 feet (13.5 m) apart
Maximum of 22.5 feet (7 m)
from the outer building walls
(so mobile users have line-of-
sight to VAPs).
Notes:
1. Check the availability of Ethernet jacks where VAPs are being installed.
2. The coverage guidelines above are conservative “rule of thumb” estimates of RF coverage per VAP, meant to be
used in scenarios in which detailed designs are not performed. When the coverage layout is designed, the coverage
per VAP is expected to increase by up to 33%. Coverage estimates in this section assume 25% overlap between
the coverage areas of neighboring VAPs to ensure robust, full coverage throughout the enterprise with no “dead
zones”.
1
S
uch as office environment with hallways, cubicles and walls.
2
Such as hospitals, manufacturing plants & buildings with cinderblock, concrete & sheet rock walls, or metallic partitions.
It is recommended to use
a floor plan when planning
the initial locations of the
VAPs. You may then move
around or add VAPs to
optimize coverage.
