Product overview
3.1
General
OneBASE™ Pico Node B is a complete pico cell radio base station intended to
enhance coverage and increase capacity in 3G (UMTS) systems. The OneBASE™
Pico Node B connects to the UTRAN system using the Iub interface.
If the UTRAN operation and maintenance system (OMC) has integrated support
for OneBASE™ Node B, then this can be used for centralized operation and
maintenance.
Local configuration is handled with the Local Management Tool – LMT. The
LMT runs on a standard portable PC and is connected directly to an OneBASE™
Node B unit through an Ethernet interface.
For remote control it is possible to use an LMT via the same IP network as would
be used for used centralized operation and maintenance.
An NTP (Network Time Protocol) Server is required in order to get the correct
time in the Node B. Each Node B has an NTP client which fetches the correct
time from the NTP Server.

Mechanical design
OneBASE™ is designed for indoor use in both office environments and public
areas like malls, airports, arenas, garages, etc. The compact size and light weight
makes it easy to place. The power consumption is low and since it uses selfconvection cooling it is completely noise free.
A complete OneBASE™ Pico Node B consists of:
•
Node B unit
•
Support unit, including AC/DC converter
•
Internal antenna (optional)
•
Cover
•
Mains cable
The Node B unit contains all electronics and interface connectors. Integrated with
the Node B unit is an optional internal antenna. External antennas may be used
instead of the internal antenna, which then is omitted.
The support unit must always be used for mounting the OneBASE™ Node B unit
to a wall. Optionally, mounting equipment for mounting in a ceiling or on a pole
is available. The support unit includes an AC/DC converter and a mains cable
with the mains end open or fitted with a protective earth plug.
The purpose of the cover is to give OneBASE™ esthetical exterior with or
without the optional internal antenna fitted. The color of the standard cover is light
gray.

Site preparation
4.1
Prerequisites
The site of the OneBASE™ Base Station should be planned in advance on the
basis of radio coverage and capacity needs. Refer to relevant information for:
•
Details on positioning of OneBASE™ and any external equipment and external
antennas, including antenna direction(s).
•
Earthed mains power source.
•
Local Area Network, LAN.
Information on configuration details regarding parameters to set during
commissioning of individual OneBASE™ Node B units.
4.2
Positioning
If the internal antenna is used, the desired coverage and direction of the antenna
determine the positioning of the OneBASE™ Node B unit. With external antennas
the OneBASE™ Node B unit can be positioned more freely.
Note: Always use the supplied support unit to fit the OneBASE™ Node B unit, and
always mount the support unit vertically for sufficient cooling.
Never mount the OneBASE™ Node B unit horizontally, even if the internal
antenna is not used.
OneBASE™ is designed for “stationary use at weather protected locations”. This
means that it can be positioned in normal indoor environments like offices, hotels
or shopping malls, but it may also be used in semi-indoor environments like train
stations, subways, garages, etc. as long as the area fulfils the environmental
requirements of OneBASE™. See Environmental conditions on page 13 for
details.
The supplied support unit is used for fitting the OneBASE™ Node B unit on a
wall. Optionally, mounting equipment for mounting in a ceiling or on a pole is
available.
The Node B unit can be locked to the support unit by using a padlock.
The unit should be installed within reach of a Local Area Network access point
and within reach of an earthed mains outlet. The unit is delivered with a power
cord with or without connector. Cables can be inserted from top or bottom on the
left side.
The minimum distances to any obstacles around the OneBASE™ Node B unit
must be kept to ensure sufficient airflow for cooling. The cooling is of the selfconvection type. No other cooling system is required if the environmental
requirements are fulfilled. See Environmental conditions on page 13.
