About this Manual
This guide provides the system specifications of the SpiderCloud Wireless® Radio Node 220 (SCRN-220).
It includes detailed hardware installation instructions, the boot sequence, and expected LED behavior both
during the boot-up and under operating conditions. An appendix shows the radio node antenna patterns.
The primary audience for this guide includes network planners, system administrators and installation
personnel. It assumes you have knowledge about networking principles, networking configuration, site
preparation, powering, and experience in hardware installation and maintenance.
Product Overview
The SCRN-220 is an integrated LTE small cell with support for Rel13 IOT devices. SpiderCloud’s scalable
small cell system, called an Enterprise Radio Access Network (E-RAN), hides the complexity of radio
management and mobility and provides operators with a single touch point to aggregate and manage a
large network of LTE small cells.
Each SCRN-220 supports 2x2 MIMO operation on configurable LTE bands, enabling higher user capacity
and average data rates per radio node coverage footprint. Each LTE carrier supports 64 active LTE users
and up to 128 RRC Connections. When used with 20 MHz channel bandwidth, an LTE carrier supports a
peak downlink rate of 150 Mbps and a peak uplink rate of 50 Mbps.
The radio node implements SON capability by listening to other radio nodes within the E-RAN and
neighboring LTE macro cells in multiple frequency bands, and performing continuous self-optimization to
provide high-quality radio coverage and mobility.
SpiderCloud radio nodes can be installed on walls or ceilings. Both network connectivity and power are
provided over Ethernet. The radio node has no fans and is completely convection cooled. Antennas are
built-in for both LTE bands, with an orderable option for QMA connectors for use with external antennas.
SCRN-220 utilizes on-chip Trusted Platform Module (TPM) functions to implement secure boot, and
establish certificate- based IPsec tunnel to SpiderCloud services node for all LTE traffic. There is no
management or console port on the radio node, and the radio node can be physically locked to prevent
theft.

Input Power
The radio node receives its power from a standard Power Over Ethernet (PoE+) switch (typical) or injector.
The radio node is fully compliant with the IEEE 802.3at PoE+ specification.
Per IEEE 802.3at, use standard Cat 5e or better twisted-pair cable with a maximum length restriction of
100 meters (328 feet) for PoE+. This restriction minimizes power loss between the PoE+ power source
and the radio node.
Power is distributed over two pairs of the four available pairs in Cat 5e or better cables. The
radio node can accept power on either used or un-used pairs.
Note
When connecting the radio node to a PoE+ switch, ensure that the switch port is statically configured to
deliver minimum 25W of power.
Some PoE switches may be factory configured to deliver lower power per port. If this is the
case change the configuration during installation.

Bracket Mounting and Cabling Guidelines
Incorrectly cabling and mounting a radio node can result in crushed cables and loss of communications to
the unit. Follow these guidelines in cabling the radio node and mounting it on the bracket:
•
Ensure that the cabling is properly routed and dressed.
•
Ensure that the radio node is fully inserted into the mount bracket so that it locks into place and
is flush. A correctly installed cable should at no time during installation impede inserting the
radio node into the mount bracket.
•
Secure the radio node to the mount bracket with a padlock or tie wrap to provide physical
security.
•
When mounting the radio node vertically, orient the bracket such that the bracket keyholes
have the narrow side up as shown in Figure 11.
Typical Radio Node Mounting Options
Radio nodes can be mounted on a wide number of surfaces including the following typical surfaces:
•
Light grill: Use bolts, nuts, and washers to secure the universal mount bracket using holes in
the light grill. Adjust the universal mounting bracket until the bracket and light grill holes align.
•
Directly on the wall or ceiling: Use drywall screws to secure the universal mount bracket
directly to sheetrock or plasterboard on the wall or ceiling.
•
Mud or plaster ring: Secure the universal mount bracket directly on the wall or ceiling as
above with a 3 1/4 inch (8.25 centimeter) mud or plaster ring between the mount bracket and
the mounting service and run the Ethernet cable through ring’s hole.
•
Existing infrastructure: Secure the universal mount bracket to existing infrastructure as long
as the radio node RF propagation or existing installed equipment is not adversely impacted.
•
Non-metal tiles: Use bracing for rear support and mount the radio node in the center of the tile
for even weight distribution. Ensure that the bracing is the same width as the tile.
•
Drop ceiling: Contact your SpiderCloud Wireless representative for recommendations of
supported third-party brackets and clamps.
Installing the Radio Node
The radio node receives its power source over powered Ethernet. If your wiring closet does not have
existing PoE+ equipment, SpiderCloud Wireless recommends a PoE+ power injector for the radio node.
See section Input Power on page 10.
The Ethernet cable can directly through a surface such as a wall or ceiling or route the cable openly:
•
Refer to Installing the Radio Node (Method 1) on page 16 for direct cable routing installation
through an opening behind the mount bracket using the shorter mount bracket.

2. The server responds with the IP addresses of the radio node and the services node (the master of
the radio node).
3. Using its own IP address, the radio node sends a Join Request message to the services node.
The radio node seeks to join the cellular network.
4. The services node responds with a Join Response message indicating whether the radio node is
allowed to join the network or not.
5. The arrival sequence begins. The services node sends the SpiderCloud software image to the
radio node.
6. The radio node boots up the received SpiderCloud software package.
7. The radio node establishes an IPsec tunnel with the services node. Based upon the radio
configuration, the radio node loads the appropriate protocol elements and joins the network.

Radio Node LED Boot Sequence
The radio node state machine is sequential and progresses in the following order:
State 0 -> State 1 -> State 2 -> State 3 -> State 4 -> State 5
A normal boot sequence transitions through all these states sequentially and the LED state transitions
accordingly. If the radio node fails to transition to the next state, the system restarts the boot sequence,
starting with State 0. You can determine the progress during the booting stages by observing the LED color
transitions. On failure, the last LED state will display the state that encountered the failure. Table 6 shows
the radio node boot sequence and corresponding LED behavior:

Description
Possible Failures and Actions
This is the initial state on startup.
The radio node bootup is controlled by
firmware in this state.
It will go through a lamp test in this
state. A lamp test involves cycling
through all LED colors.

A radio node should not stay in
this state indefinitely.
Note: Flashing Green is also
used to indicate a radio node
that has been administratively
disabled. This can be
determined from the CLI.
The radio node starts by sending out a
DHCP Request.
No DHCP Response, IP
Address not allocated.
The radio node moves to the next state
(State 2) upon receiving a DHCP
response and an IP Address.
Check cabling, DHCP Server
configuration.
The radio node has an IP Address and
sends a UDP Join request to the
Serving services node.
No IP reachability to the
services node.
The radio node moves to the next state
(State 3) upon getting a JOIN GRANT
from the services node.
3. TFTP
This state should be very short
lived and should transition to the
next state immediately.
The radio node proceeds next to
download the operating system image
from the services node.
The radio node moves to the next state
(State 4) after the image has been
downloaded.
SpiderCloud Wireless, Inc.
Check IP network between
radio node and services node
for routing issues.
Failure to download TFTP
image.
Check firewall between radio
node and services node.

Radio Node LED Management
The LED display is active by default, but can be deactivated in light-sensitive environments as needed.
Even when the display is disabled, the LED will be lighted during the following conditions:
•
while the radio node is booting
•
if the radio node or cell is in fault state
•
if there is an active emergency call
•
if the locate radio node feature is active
•
if the follow IMSI feature is active
Table 7 shows the default LED behavior of the radio node:
