Customer Story
EDF Energy
Digi helped the largest
electricity distribution
network owner in the UK
solve the problem of remotely
monitoring its 400 electricity
substations across a large
geographic region. Digi
TransPort
®
enterprise wireless
routers provide a reliable
connection to EDF Energy’s
substations. Digi Remote
Manager software enables easy
configuration and management
of the units.
“…we no longer have to
dedicate time and money
sending out our staff to
either fix problems or wait
for external engineers at
substations.“
- Roger Yeo, Sr. Project
Engineer, EDF Energy
EDF Energy also uses Digi
TransPort routers to link its
legacy monitoring system
to a wireless IP network.
Performance information is
sent initially via EDF Energy
Networks’ VSAT satellite
network. However, if there is
a network problem or if the
primary connection becomes
unavailable, the routers
intelligently detect the issue
and switch to a GPRS mobile
network connection.

Cellular Routers
Digi TransPort cellular routers offer an all-in-one mobile
communications solution with secure high-speed wireless
connectivity to remote sites and devices for primary or backup
wireless broadband network connectivity. These multi-
function cellular routers feature a rugged flexible design with
optional integrated Wi-Fi access point (with multi SSID) /
Client, USB, serial and 4-port Ethernet switch, as well as a
variety of configuration options including multiple serial ports
for simple serial-to-cellular IP connectivity.
Problem
Changing cellular networks requires expensive hardware replacement.
Switch, recloser and capacitor bank controllers require secure two-way
communications.
Weak signal strength due to remote locations and high signal
interference in substations.
Solution
Digi TransPort routers are carrier agile, able to switch networks without
replacing product.
Digi TransPort routers offers full set of enterprise security features
including 256-bit AES encryption and FIPS 197.
Digi TransPort routers can be pole mounted or placed outside of
substation control houses and optimized with external antennae.
Utility Communication Hub
The Digi Utility Communications Hub offers utilities and
energy service providers a customizable remote command
center for Distribution Automation and Commercial and
Industrial metering applications.
Each hub is built around one of Digi’s GSM or CDMA
cellular routers and supports wired connections to serial
and Ethernet equipment as well as wireless communication
to local devices via ZigBee, Wi-Fi or license-free RF. An
integrated power supply and optional surge arrestor and
battery backup ensure reliable communication to grid assets.
Problem
Complicated installations require training and documentation.
Expensive and complicated to support a piecemeal solution with product
from many vendors.
