Era System Overview

RA YSTEM
Era™ coordinates wireless capacity throughout the entire coverage area via a single centralized head-end
location or from an operator's existing C-RAN hub. Based on ION
standard IT cabling as ION-E and is compatible with ION-E deployments. Era systems bring together licensed
wireless and power, plus Gigabit Ethernet for WiFi into one wireless system that can scale to building size and
is technology and spectrum agnostic and adaptive. An Era system comprises the components listed below.
Central Area Node (CAN)—provides server-level control and primary signal distribution. It combines
•
the signals from multiple operators and distributes those signals within a venue or multiple venues.
There are two configuration modes available for the CAN: Classic and Switching.
The Classic CAN configuration is appropriate for when all the BTS and Baseband sources are located
–
in a centralized space in the same venue as the Classic CAN. You install RF Donor (RFD) Cards and
CPRI Digital Donor (CDD) Cards in a Classic CAN, which digitizes the analog BTS signals from the RFD
Cards and combines those with the BBU CPRI digital signals from the CDD Cards, and then distributes
the RF signals to the TENs. The TENs then provide the RF signals to the Access Points (APs). The
Classic CAN also supports APs that are directly connected to CAT or OPT Cards installed in the Classic
CAN chassis. Wide-area Integration Nodes (WINs) are not supported by a Classic CAN. Users have full
and flexible control of all signal routing via the Era GUI.
The Switching CAN configuration is appropriate for when WINs are required to allow operators to
–
bring in baseband signals from multiple remote locations to fully leverage the C-RAN architecture in
their hubs. All operator Baseband signals (analog BTS and BBU CPRI) are supplied to the Switching
CAN by the WINs, so no RFD or CDD Cards can be installed in the Switching CAN. The Switching CAN
then combines the signals from all WINs and distributes those signals to the TENs, and the TENs
provide the signals to the APs. APs are not directly connected to a Switching CAN. Users have full and
flexible control of all signal routing via the Era GUI.
This guide uses "CAN" to collectively refer to Central Area Nodes. When information pertains to a specific
CAN mode, "Classic CAN" and "Switching CAN" will be used.
Wide-Area Integration Node (WIN)—interfaces between a Switching CAN and RF sources, which
•
makes C-RAN possible in Era by allowing operators to bring in signals from multiple remote locations
kilometers away. You install RFD and CDD Cards in the WIN, which takes the analog BTS signals from the
RFD Cards and combines those with the BBU CPRI digital signals from the CDD Cards, and distributes the
RF sources to a Switching CAN.
Transport Expansion Node (TEN)—is an expansion node connected to the CAN via fiber and can be
•
located throughout the venue coverage area. A single TEN can support, dependent on the AP type and
powering method, 12 to 32 Access Points (APs), which greatly reduces the number of fiber runs between
the head-end and each AP.
Access Point (AP)—connects a Classic CAN or TEN to antennas or other wireless devices. On the
•
downlink, an AP converts data arriving at the AP to analog signals and sends them to an antenna. On the
uplink, received signals are digitized and serialized into data streams which are sent back to the Classic
CAN or TEN. APs support Gigabit Ethernet pass-through for WiFi, IP cameras, or other devices in addition
to wireless over a common cable. An AP can be any of the Universal Access Points or Carrier Access Points.
This guide uses "Access Point (AP)" to collectively refer to the Universal Access Points (UAPs) and the
Carrier Access Point (CAPs), and "Fiber APs" to collectively refer to Fiber CAP Ls and CAP Ms. When
information pertains to a specific AP type, that AP will be identified.
