RoHS and WEEE Compliance
The Aprisa LTE is fully compliant with the European Commission’s RoHS (Restriction of Certain Hazardous
Substances in Electrical and Electronic Equipment) and WEEE (Waste Electrical and Electronic Equipment)
environmental directives.
Restriction of hazardous substances (RoHS)
The RoHS Directive prohibits the sale in the European Union of electronic equipment containing these
hazardous substances: lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBBs),
and polybrominated diphenyl ethers (PBDEs).
4RF has worked with its component suppliers to ensure compliance with the RoHS Directive which came into
effect on the 1st July 2006.
End-of-life recycling programme (WEEE)
The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment.
Under the Directive, used equipment must be marked, collected separately, and disposed of properly.
4RF has instigated a programme to manage the reuse, recycling, and recovery of waste in an environmentally
safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic
Equipment 2002/96/EC).
4RF invites questions from customers and partners on its environmental programmes and compliance with
the European Commission’s Directives ([email protected]m).

Compliance General
The Aprisa LTE router operates within frequency bands that are controlled through spectrum license
managed by the carriers
1
. Devices using these frequencies must meet the regional regulatory requirements
in addition to any requirements put in place by the carriers.
It is the responsibility of the user, before operating the equipment, to ensure that where required the
appropriate regulatory and regional carrier requirements have been met.
Changes or modifications not approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
Equipment authorizations sought by 4RF are based on the Aprisa LTE router being installed at a fixed
restricted access location and operated within the environmental profiles defined in Table 1; operation
outside these criteria may invalidate the authorizations and / or license conditions.

RF Exposure Warning
WARNING:
At least 20 cm separation distance between the antennas of the collocated transmitters
and the user’s body must be maintained at all times.
To comply with FCC/IC regulations limiting both maximum RF output power and human
exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-
only exposure condition must not exceed the limits stipulated in Table 3.
The radiated power of a collocated transmitter must not exceed the EIRP limit
stipulated in Table 3:
ATTENTION:
Une distance de séparation d'au moins 20 cm entre les antennes des émetteurs
colocalisés et le corps de l'utilisateur doit être maintenue à tout moment.
Pour se conformer aux réglementations FCC / IC limitant à la fois la puissance de sortie
RF maximale et l'exposition humaine au rayonnement RF, le gain d'antenne maximal, y
compris la perte de câble dans une condition d'exposition uniquement mobile, ne doit
pas dépasser les limites stipulées dans le tableau 3.
La puissance rayonnée d'un émetteur colocalisé ne doit pas dépasser la limite indiquée
dans le tableau 3:

Introduction | 17
Aprisa LTE User Manual 2.1
LTE Product Overview
The 4RF Aprisa LTE is a 3GPP LTE router for critical infrastructure monitoring and control for smart SCADA
(e.g. electricity, water, oil and gas industries), transportation, smart city, backhaul, and industrial
communication hardened for both mission and business critical applications.
Key Features
•LTE wireless data services providing broadband enhanced LTE data rates and latency
•Supports strong CSNA complaint encryption, authentication and hashing algorithms (eg RSA4096 and
SHA384).
•GRE VPN, and IPSec support, the Aprisa LTE protects against vulnerabilities and malicious attacks
•Serial and Ethernet ports with an SFP port for additional electrical / optical connection
•Integrates into a wide range of industrial and utility applications with redundant carrier connections
for public and private networks
•Mobility and Wi-Fi supporting advanced remote visibility in vehicle networks with GNSS location
•GNSS navigation and 2x2 MIMO Wi-Fi access point/client for robust workforce mobility and
communication
•Advanced L2 / L3 capabilities: selectable L2 or L3 modes with VLAN, QoS, NAT, IPv4, and IPv6
•Transition support to maximize performance and prioritize mission critical traffic while meeting
tough security and IP network policy imperatives
•A wide temperature range using full specification industrially rated components and shared Aprisa
family heritage
•Easily managed with SuperVisor GUI local element management via HTTPS
•Element management over the air via SNMP to allow network-wide monitoring
•Control, and orchestration via a variety of supported third party network management systems
•Failover: single LTE router, dual SIM with switch over, and interface failover to provide alternate
path routing on WAN or FAN failure
