Application guides for other use cases can be made available as needed. Note that some use cases may have regional regulatory limitations.

Technical Specifications Radio

Two products form radio links for use in either of the following scenarios:

• between a vehicle such as a train and static infrastructure (TN201SC in conjunction with a DN201SC) or

• between nodes as part of a backhaul fixed wireless system where two DN201SC units communicate.

• between vehicles where vehicles each have one or more TN201SC nodes installed.
  Note: Point to multi-point use is not excluded from these usage scenarios but may be subject to further licencing and system design.

• Customers are responsible for defining and maintaining system performance in the context of radio planning, particularly with respect to maintaining line of sight between communicating units, managing range verses performance characteristics of their system and in understanding environmental specifics of their system. Information on radio performance to assist this decision making can be found in the radio deployment guide (BW-000976).

• The maximum unit spacing and performance achieved will depend on several factors, including:

  • Specified weather limits including rain intensity and environmental temperatures.
  • Data throughput minima (average and absolute minima).
  • Robustness of connection required.
  • Network redundancy considerations, if available.
  • In multi-unit vehicle installations, the separation of the TN units on an individual vehicle on a single vehicle network.
  • The dynamics of the system, if any.

In all cases
Line of sight must be maintained at all times between the two antennas – there must be no radio obstructions. Note the radio beam cannot be considered a zero-width beam; a radio guide identifying line of sight constraints is available from Blu Wireless.

For EMC reasons the power cable used should be shielded and the shield connected to a suitable grounding point, unless other arrangements are made for earthing described here.

Ground| Grounding points are available on the unit should local installation requirements demand that the unit enclosure be earthed. It is not required to ground the unit for product safety reasons using this connection however the case of unit shall be earthed for EMC reason by some means. Two threaded holes are available allowing multiple connections if needed.

Electrical protection, earthing and isolation

CAUTION: These products require the case to be earthed for Electromagnetic compatibility reasons. This may be achieved via the earth terminals on the case or the power cord shield if fully connected. The casing of units need not be earthed for electrical safety purposes, but the product supports this, should local regulations require it. Note that the power cable shall be screened, and the screen shall be suitably grounded. This is for EMC reasons. Should the DN201SC units require an earth this may be achieved by use of either or both threaded case points shown in Figure 5. Note that if using a DC power cable with a screen which is connected at both ends, or an SFP which has its shield connected to an external earth, an alternative earth path may also exist, and installers should ensure that any such arrangement complies with their applicable regulations on earthing.

Isolation
The DC power input on the DN201SC unit is isolated from the case and internal electronics via an internal isolated power supply.
