Please note, this blog post is offered for reference only to be used as a general guideline for
networks utilizing the 7705i MultiNet Receiver (similar guidelines are being developed for next generation 7705ii MultiNet Receiver networks). Not all networks are the same, each private network has a different set of variables and unique configuration. Field Technicians and Installers should always seek appropriate advice from a member of the AES Support team if they have a question or need assistance.

 

Based on Our Experience


experience

 

The capacity of Subscribers supported by a set of IP Links or Hybrid Subscribers when establishing a network will be up to 1,200 Subscribers. Actual capacity may be higher or lower depending on geography, environmental factors, deployment strategies (frequency of Check-Ins, Time-to-Live settings, etc.), and quality of installations. 

Factors that Impact Network Performance

NetworkPerformance_variables

The list below provides examples of the more common environmental, geographic, and programmatic factors which may affect network performance and overall capacity:

  • Drastic elevation changes in the topography or terrain – both natural and man-made
  • Urban areas v. suburban or rural areas
  • Density of subscribers
  • Subscriber deployments over a large geographic area - can require additional IP Link(s)
  • Frequency of Check-In’s
  • Packet TTL settings
  • # of Events being reported within a given time period

 

Maximum Network Size Recommendations

2.0_Diagram_03092017-2

  • Subscribers per MultiNet Receiver: Up to 9,000
  • Business Units per MultiNet Receiver: Up to 15 (maximum)
  • IP Links (or Hybrids) per MultiNet Receiver: Driven by network need
    (do not exceed 9,000 Subscribers or 25 IP Links)
  • Subscribers per IP Link: Up to 1,200 (based on factors referenced above)

For networks that exceed the above recommendations, AES suggests implementing a multi-frequency or multi-receiver strategy whereby the network is segmented into smaller subnets.

Antenna Selection

Antenna selection is also an important aspect of network performance.  Always use the lowest gain antenna possible to achieve a good signal.  Using a higher gain antenna will cause overreach of the Radio Frequency signal.  The following are effective distance potentials in an ideal RF environment for the various antennas available from AES (these are distance estimations only; actual performance will be affected by installation quality, cable length, and other environmental factors):

  • Rubber Duck - up to 3 miles
  • Stealth - up to 3 miles
  • 3dB - up to 3 miles
  • 5dB - up to 5 miles
  • 6dB - up to 10 miles
  • 9dB - up to 15 miles

Time to Live (TTL)

How to properly program and set packet ‘Time To Live’ (TTL) function is a topic we are
frequently asked about. In most cases, the default settings will be appropriate. You may
never have to use it, but in the event a condition arises causing congestion to occur you’ll
be glad to have the TTL functionality in place to help manage communication and maintain
normal status. We strongly suggest you check to see if you have the latest firmware version
release installed and use the current suggested settings for all and new default TTL values.

This can help free up airwaves for critical packets:

  • Check-In, Status, and Special are set to ‘10 minutes’
  • Alarm, Trouble, Restoral, and IntelliTap are set to ‘3 hours’

Preventative Maintenance

AES also recommends the implementation of a comprehensive preventative maintenance program to ensure optimal network health.  The following link is to the AES recommended preventative maintenance plan:  http://insights.aes-corp.com/blog/preventative-maintenance

 

Battery Monitoring

Regular monitoring of your batteries can help avoid potential issues like Subscribers locking
up, overheating, or causing communication failures resulting in ACK Delays. A few key
things to remember:

  • Bad batteries that are old and/or battery cable terminals that are corroded need
    to be cut and replaced before another new or used battery can be attached
  • Batteries need to be tested on a regular basis
  • Observing DVM readings (attach red lead to red terminal and black lead to
    black terminal) and writing the date of install on the batteries (like you
    would for an oil change on your car) can help you monitor how long a battery
    has been in service
Following these few simple steps can help you avoid having to send units back for RMA/
Repair due to burnt overheated components because of bad batteries.

 

Repairs

Image result for Repairs

When components of your AES network require repair, those repairs should only be performed by a qualified AES trained technician.  Failure to do so may void your product’s warranty.  Regardless of your product’s warranty status, any repairs should be performed by an AES trained technician.  There are many aspects of AES products that need to be considered during the repair cycle to ensure compatibility.  Contributing factors include hardware version, firmware version, chipset, and others.  AES Technical Support can assist in determining interoperability between components.

 

Stay Up To Date

As with any technology, improvements are implemented throughout a product’s lifecycle.  Improvements are made towards improved efficiency, reliability, and overall performance.  Technologists encourage organizations to develop and implement comprehensive technology refresh strategies to ensure their investments are protected.  Similarly, AES recommends that our customers implement technology refresh plans specific to their AES-IntelliNet and IntelliNet 2.0 networks.  The most diligently executed maintenance plan will not prevent obsolesce or mechanical failures associated with prolonged use.  As such, our customers should plan to refresh their various AES network components accordingly.  Customer should inspect each component annually to verify proper operational performance and visually inspect the component’s physical condition.  Please refer to the Discontinued Products list posted on our aes-corp.com website under the Products & Services tab on the main menu bar.

The table below provides basic refresh guidance:

Network Component Refresh Frequency
     Subscriber

Every 7 to 10 years based on operational environment

     IP Link Every 7 to 10 years based on operational environment
     MultiNet Receiver Every 7 to 10 years based on operational environment
     Antennas Every 1 to 3 years for outdoor, will vary based on exposure and climate
Every 5 to 7 years for indoor
     Coaxial Cable

As necessary based on physical and operational inspections
Outdoor, unprotected coaxial may require frequent replacement in harsh climates
