Robust, Optimized RF Communications
The MDS Intrepid Series seamlessly change modulation and throttle
throughput based on changes in signal strength, whereas other
solutions just "drop the link." Dropping the link is the last resort for the
MDS Intrepid Series.
Additionally, when link quality falls below a pre-set standard, MDS
Intrepid Series automatically searches for a more clear channel based
on a pre-set list of available channels. Finally, MDS Intrepid Series offer
bandwidth options that may be implemented to improve immunity to
disturbances.
MDS Intrepid Series is available in the unlicensed 2.4, 5.4, and 5.8
GHz bands and the U.S. public safety 4.9 GHz band. Various agency
approvals for these frequencies have been granted from FCC, IC, and
ETSI. Interface options include Fast Ethernet plus 0, 1, or 2 E1s/T1s
(standard IDU) or two Fast Ethernet ports plus 4 E1s/T1s (industrial-
grade IDU).
Link information is readily available for analysis with a few simple
actions and external events trigger alarms via dry contact alarm
inputs. At any time, factory settings can be restored for each outdoor
unit (ODU).
Highly Reliable
With a bit error rate (BER) of 10E
-11
for all communications (Ethernet or
T1/E1), a patented fast Automatic Retransmit reQuest (ARQ) algorithm,
and a TDM clocking accuracy of five parts per billion (PPB) for T1/
E1 circuits, support for time-sensitive links and success statistics
for channel availability and reliability are some of the highest in the
industry.
Indoor Unit/Outdoor Unit Configuration
The MDS Intrepid Series is offered as a split mount system consisting
of an Indoor Unit (IDU), which contains interfaces and protocol
firmware support, and an Outdoor Unit (ODU), which contains the RF
and frequency-specific firmware. The ODU may be purchased with an
integrated antenna or with an external antenna connection when it is
desirable to have the ODU readily accessible or more environmentally
controlled.
The IDU is offered in an industrial-grade enclosure or a more cost-
effective standard enclosure. Alternatively, a power over Ethernet (PoE)
IEEE 802.3AF option is available.
