Overview
The SCALANCE M874-3
is a mobile wireless router for cost-
effectively and securely connecting Ethernet-based subnets
and programmable controllers via the 3rd generation mobile
wireless network (UMTS) and it supports HSPA+ (High Speed
Packet Access). Thus, it allows high transfer rates of up to
14.4 Mbit/s in the downlink and up to 5.76 Mbit/s in the uplink
(depending on the infrastructure of the mobile wireless
provider).
The SCALANCE M874-2
is a mobile wireless router for cost-
effectively and securely connecting Ethernet-based subnets
and programmable controllers via the 2nd generation mobile
wireless network (GSM) and it supports GPRS (General Packet
Radio Service) and EDGE (Enhanced Data Rates for GSM
Evolution).
The security of access and communication is ensured by the
security functions of the integrated firewall and by VPN tunnels
(end-to-end connection encryption through IPsec tunneling).
SCALANCE M875
is a UMTS router for wireless IP communi-
cation between Industrial Ethernet-based programmable
controllers via mobile radio networks of the 3
rd
generation
(UMTS) and the 2
nd
generation (GSM)
•
High data transfer rate thanks to HSDPA
•
Integrated security functions with firewall
•
Use as VPN end point (IPsec)
•
Approved for railway applications
SCALANCE M812-1
and
SCALANCEM816-1
are DSL routers
for the low-cost and secure connection of Ethernet-based
subnets and automation devices to wired telephone or DSL
networks that support ASDL2+ (Asynchronous Digital Sub-
scriber Line). This allows the devices to have high downlink data
rates of up to 25 Mbit/s and uplink data rates of up to 3.5 Mbit/s.
The security of access and communication is ensured by the
security functions of the integrated firewall and by VPN tunnels
(end-to-end connection encryption through IPsec tunneling).
The
SCALANCE M826-2
is an SHDSL modem for low-cost, se-
cure connection of Ethernet-based subnets and programmable
controllers via existing two-wire or stranded cables and supports
the ITU-T standard G.991.2 as well as SHDSL.biz (single-pair
high-speed digital subscriber line). This gives the device high
symmetrical data rates of up to 15.3 Mbit/s per wire pair.
The security of access and communication is ensured by the se-
curity functions of the integrated firewall and by VPN tunnels
(end-to-end connection encryption through IPsec tunneling).
