1. Overview
The DN201SC product delivers high bandwidth connectivity in two primary scenarios using mmWave technology in the
57-71 GHz radio band. The two scenarios are:
•For rail or transport use between a vehicle and static units when combined with the vehicle unit TN201SC. In this
scenario the DN201SC is part of the static infrastructure.
•For fixed wireless systems where the DN201SC is used at both ends of the radio link.

6. 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.

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.
