REGULATORY OMPLIAN E and NOTI ES
F Notice
T is device complies wit part 15 of t e FCC Rules. Operation is subject to t e following two conditions:
1. T is device may not cause armful interference, and
2. T is device must accept any interference received, including interference t at may cause undesired operation.
NOTE: T is equipment as been tested and found to comply wit t e limits for a Class TBD) digital device, pursuant to Part 15 of t e
FCC Rules. T ese limits are designed to provide reasonable protection against armful interference in a residential installation. T is
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance wit t e instructions, may
cause armful interference to radio communications. However, t ere is no guarantee t at interference will not occur in a particular
installation. If t is equipment does cause armful interference to radio or television reception, w ic can be determined by turning t e
equipment off and on, t e user is encouraged to try to correct t e interference by one or more of t e following measures:
-- Reorient or relocate t e receiving antenna.
-- Increase t e separation between t e equipment and receiver.
-- Connect t e equipment into an outlet on a circuit different from t at to w ic t e receiver is connected.
-- Consult t e dealer or an experienced radio/TV tec nician for elp.
CAUTION: S ielded I/O cables must be used and all covers must be in place w en operating t is equipment.
anadian Department of ommunications compliance statement:
T is equipment does not exceed Class A limits per radio noise emissions for digital apparatus set out in t e Radio Interference
Regulation of t e Canadian Department of Communications. Operation in a residential area may cause unacceptable interference to radio
and TV reception requiring t e owner or operator to take w atever steps are necessary to correct t e interference.
Avis de conformite aux normes du ministere des ommunications du anada:
Cet equipment ne dépasse pas les limites de Class A d’émission de bruits radioélectriques pour les appareils numériques tels que
prescrites par le Règlement sur le brouillage radioélectrique etabli par le ministére de Communications du Canada. L’exploitation faite en
milieu résidentiel peut entrainer le brouillage des réceptions radio et télé, ce qui obligerait le propriétaire ou l’operateur à prendre les
dispositions nécessaires pour en éliminer les causes.

1. General Description
1.1 Section Overview
This section contains information about the VMBR-1520 (ViaSat)
Mobile Broadband Router, including a description of the Satellite
Network, an equipment list, and a description of the components
contained in the VMBR-1520.
1.2 Satellite Network
The VMBR-1520 is designed for use in the ArcLight
TM
Internet Protocol
(IP) based STAR topology Very Small Aperture Terminal (VSAT) network
as shown in Figure 1-1.
Figure 1-1. Typical VSAT Network
The STAR network consists of a broadband spread spectrum Forward
Link (FL) transmission from a central hub to the Mobile Broadband
Routers, and individual, random access, spread spectrum Return Link
(RL) transmissions from the Mobile Broadband Routers to the central
hub. The Return Link signals can simultaneously overlay in the same
bandwidth as the Forward Link.
To recover the Return Link, the Mobile Broadband Router features two
ViaSat-proprietary technologies Code Reuse Multiple Access (CRMA)
and Asymmetric Paired Carrier Multiple Access (A-PCMA).
The VMBR-1520 is expected to be installed as part of a Mobile
Terminal, along with the following additional components

- Satellite Antenna System (SAS) An SAS consists of a steerable
antenna, an Antenna Control Unit (ACU), and a Ku-band
transceiver. The Ku-band transceiver includes a Phase-Lock
Loop (PLL) Low-Noise Block Down-converter (LNB), a Ku-band
Block Up-converter (BUC), and a power amplifier;
- Intra-Facility Link (IFL) An IFL consists of coaxial cables
connecting the Mobile Broadband Router with the SAS. An
additional cable will be provided for power and communications
between the SAS and the Mobile Broadband Router.
