Engineering Services
Why engineering services?
There are no short cuts to a successful wireless link and design.
Proper engineering and design must always be considered in designing a
wireless system. Whether installing a complex, 40-mile, licensed,
high capacity SONET microwave radio system with monitor hot standby
and space diversity or a simple WLAN Ethernet Bridge across a parking
lot -- a systematic, detailed and scientific approach is always
recommended to ensure predictable results. Southwest LAN Connections
successfully combines the discipline of science with the consistency
of field experience in our Engineering Services to dispel the common
myths surrounding both licensed and license-exempt
systems.
Customer Wireless and Networking Requirements
Our first step for any
wireless system design, is to engage our pre-sales engineers in the
quest to understand your expectations and wireless networking
requirements.
 |
What is the criticality of this wireless system?
|
 |
What are your bandwidth requirements?
|
 |
Are you planning on implementing VoIP (Voice over IP
Services)?
|
 |
Should this system provide your business future network
scalability?
|
 |
Will this wireless transport require voice, video and data?
|
 |
Does your data require a high capacity encryption solutions?
|
 |
Will SNMP-based network management be required?
|
By posing these questions, we will be able to
determine the optimum wireless solution for your business networking
requirements.

Preliminary Engineering Study ( Wireless Feasibility and budgetary
cost)
The
preliminary study will determine wireless feasibility and budgetary
costs. With customer provided addresses, estimated heights of
buildings, trees, potential obstructions and an extensive terrain
database, we perform terrain studies to generate a preliminary path
profile. We then use digital satellite imagery for a 3-D snap shot of
the wireless link. The data obtained in this phase can help us
determine if communication structures, such as a tower, need to be
involved or if any permits are required by city, county or government
ordinances.

Path
Propagation Study ( Site and Path Survey)
This
phase of the design process involves the actual site and field survey,
where we gather the following pertinent data and verify the results of
the preliminary Engineering Studies.
 |
Verify
terrain topology and path surface characteristics, elevation heights
of existing buildings or communication towers for determining
antenna centerline |
 |
Identification of potential obstructions and heights |
 |
Identification of interference sources, including foreign system
interferences |
 |
Assess
structure type for antenna mounting engineering purposes
|
 |
Assess
the need for a soil analysis or PE certified structural analysis |
 |
Identification of grounding sources and feeder cable raceways |
 |
Site
component inventory of existing wireless system on or around the
building |
 |
Aesthetics consideration as specified by the building owner or
landlord |
Our GPS
receivers, LDME (Laser Distance Measurement Equipment), abney level
will collect critical information needed to perform Path Loss
reflection, link and reliability analysis for your system.

Wireless
Network Map and RF Coverage analysis
The
wireless network map is an overview of the system, providing
information such as geographic coordinates, path lengths, path
directions (azimuths) and angles between transmitters and receivers.
These maps can be very beneficial for expansion considerations or for
interference analysis of your wireless system. For point-to-multipoint
systems we can also provide RF coverage analysis to determine the size
and type of sector antennas to cover a specified area

Interference Analysis / Prior Coordination Notices
Licensed
Systems: Licensed radio systems are regulated by the FCC rules
governing fixed microwave under Part 101 CFR Title 47. These rules,
such as the mandatory PCN (Prior Coordination and Notices), subsequent
FCC filings and other related services can be completed and submitted
by Southwest LAN Connections.
License-Exempt Systems: For ISM and UNII band,
license-exempt systems, a spectrum analysis is highly recommended.
Previously identified potential interference sources need to be
analyzed to determine the optimum antenna placement and other
interference mitigation procedures. Southwest LAN Connections also
offers our Spectrum and Interference analysis to companies with
existing co-located, license-exempt systems. In light of the
increasing demand for these systems, it is critical to be able to
address and mitigate evolving interference conditions as they change
in order to preserve the viability of your wireless investment.
