XYZ Pty. Ltd.

• Case Study 1 XYZ Pty. Ltd. (Under NDA)
• Requirements
• Reliable network connectivity (point-point)
  between multiple buildings separated by a large
  roadway.
• Conventional Ideology Limitations
• Fibre cabling costs were to exceed 500,000 AUD.
• The project required extensive planning due to
  the requirement to trench under the roadway.
• Any alterations to the roadway required a lengthy
  approval process.
• The estimated lead time to implementation was
  6-18 months.
• The Simply Wireless Solution
• Simply Wireless provided an appropriate
  point-point solution for less than 60,000 AUD.
• The wireless solution had a three (3) week
  implementation lead time.
• Wireless Bridge Benefits
• Large cost savings.
• No development approval required.
• Very low lead time to implementation.

XYZ Pty. Ltd.

• Case Study 2 XYZ Pty. Ltd. (Under NDA)
• Requirements
• Reliable and scalable network (point-multipoint)
  connectivity between multiple buildings separated
  by open space, other buildings and grassed areas.
• Conventional Ideology Limitations
• Fibre, cabling, switches and integration costs
  were to exceed 100,000 AUD.
• The fibre solution could not be easily
  re-designed.
• Additional building were to cost approximately
  20,000 each.
• The project required extensive planning due to
  some trenching requirement.
• The estimated lead time to implementation was 2-6
  months.
• The Simply Wireless Solution
• Simply Wireless provided a point-multipoint
  solution for less than 40,000 AUD.
• Additional buildings could be brought on for less
  than 10,000 each.
• The wireless solution had a three (3) week
  implementation lead time.
• Wireless Bridge Benefits
• Large cost savings.
