Coverage and Installation Planning
Note: The following section provides the information required for planning the VAP installation
on a single floor. In a multi-tier installation, this procedure is performed for each floor
separately.
The maximal coverage area of each VAP is affected by the density and type of environment to
be covered. Therefore, it is recommended to determine the location in two phases:
•
Plan the
ideal location of each VAP in order to achieve complete coverage of the floor and
then
•
Select
exact location according to the location feasibility, where each VAP unit may be
mounted on a wall or placed on a desk and an option for an external antenna is available
(for specific VAP models).
The supplied services (wireless only or Ethernet and wireless) depend on the jack to which the
VAP is connected:
•
If the jack supports an active Ethernet connection – the VAP will distribute LAN traffic along
with the wireless service. For more information see section
4.3.1.
•
If the jack is not currently active (not connected to an Ethernet switch) - the VAP will
distribute only the wireless services.
This section provides information on coverage criteria in various types of environments (Open,
Standard, Dense and Merged) and provides rules-of-thumb for various installations of the VAPs.
Note: Section
3.4 provides a detailed example of installation planning in various types of
environment. It is recommended to review this example after reading this section.
3.3.1 Types
of
Environments
This section describes the different types of installation environments and provides guide lines
for best coverage of each type of space.
The coverage guidelines in this section 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”.
The coverage guidelines in the following tables are provided for the
higher frequency bands
(UMTS & PCS). The lower frequency bands (DCS, EGSM & CELL) are omitted from the tables
since coverage in these bands will be better than that of the higher frequency bands. The
coverage of a dual-band system will be determined by the higher frequency band (i.e. PCS for
CELL/PCS and UMTS for EGSM/UMTS and DCS/UMTS).
