1 Introduction to Flexi Lite BTS

Nokia Siemens Networks Flexi Lite BTS (FQGA - 2100 MHz frequency variant) is a

small base station optimized for indoor and outdoor micro-cell environment. The main

application of this extremely compact base station is to help deliver an improved mobile

broadband experience by enhancing coverage and capacity both outdoor and indoor.

Flexi Lite BTS can be used to add capacity cells in urban and dense urban areas if new

frequency carriers for macro cells are not available. It can be also deployed to cover

traffic hotspots or to fill network coverage holes as well as improve coverage inside

buildings, for example at airports and railway stations. It provides an efficient way to

meet market growth while simultaneously offloading voice and data traffic from the

mobile Communications Service Provider’s (CSP) macro network. Flexi Lite BTS can be

used for both micro cell and pico cell applications.

Flexi Lite BTS is all-in-one device equipped with System Module functionality, RF

module, and built-in IP transport that enable a cost-effective site solution and high-

speed connections.

Output power is high enough to support indoor coverage building from outdoor sites. It

is also high enough to drive distributed antenna system for indoor coverage. It also

supports 2TX MIMO.

Figure 1 Flexi Lite BTS 2100

Typical micro-cell outdoor antenna deployments are below roof-top in heights of about

5 to 15 meters above the ground level and on poles. Typical indoor deployments include

exhibition halls, shopping malls, large office spaces, airports. Antenna height in indoor

installations is typically from 2 to 5 meters above ground level. In indoors Flexi Lite BTS

is to be mounted either on the wall or the ceiling or connected to an external distributed

antenna system.

Flexi Lite BTS is connected to RNC through 3GPP 25.430 UTRAN Iub interface, general

aspects and principles.

Benefits

7Benefits

Flexi Lite BTS provides a vast number of benefits for the operator.

Easy installation

Flexi Lite BTS offers new site deployment possibilities thanks to its compact size and

light weight (approx. 11 kg (24.25 lb.)), which makes it easy and fast to deploy. Active

cooling enables minimum installation clearance which allows Flexi Lite BTS to be

installed in small areas like crowded sites, utility rooms or inside the cabinets. This small

base station can be also installed back to back at compact multiband and multiradio

sites, which can bring further savings in the form of lower and easier site acquisition and

rental costs and allows CSPs to extend coverage to areas that were previously inacces-

sible. Further, Flexi Lite BTS incurs lower installation cost as it can be deployed by a

single person and also reduces running costs as it consumes little power and yet

delivers high capacity. Additionally, it can power P+E-compliant devices on the site.

The small factor of the BTS allows making it unnoticeable in locations such as exterior

walls, billboards, lamp-posts, and bus stops.

The BTS can be installed in any orientation. However, in outdoor installation protection

against rain has to be provided. Without protection the cables must be faced down.

Power source for other devices

Flexi Lite BTS can also provide the power to an external device if it meets P+E require-

ments.

Low acoustic noise

Flexi Lite BTS uses silent active cooling.

Easy commissioning

Flexi Lite BTS supports wizard-based commissioning via the BTS Site Manager. The

configuration can be saved to a file which can be used later as a template.

Auto-connection and auto-configuration is supported as in Flexi Multiradio BTS or Flexi

Multiradio 10 BTS.

Reliable operation

Simplicity and speed of maintenance procedures improve operation reliability. Mainte-

nance is improved by module integration and automatic fault detection procedures.

Special attention has been paid to Flexi Lite BTS software start time, reducing, for

instance, downtime when a new software package is put into use.

Software features

Flexi Lite BTS with SW version WL7.0 2.0 has RU30 EP2 feature parity. For the full list

of features and their descriptions, see WCDMA RAN Feature List.

down to -107 dBm in steps) receivers. Flexi Lite BTS operates at:

• Uplink: 1920 – 1980 MHz

• Downlink: 2110 – 2170 MHz

Two-way receiver diversity is supported.

The RF output power can be set down to low power use (250 mW + 250 mW) with a

parameter, in ~1dB steps. BTS maximum output power (between 250 mW and 10 W)

can be set locally with a commissioning parameter or via NetAct. Note that maximum

output power limit must follow country-specific guidance if applicable.

Flexi Lite supports 3GPP Wide Area TS 25.104 Rel-9 standard.

8.1 Integrated antenna

Integrated antenna is an optional item and is included for both branches. Integrated

antenna is selected with a jumper cable connected from the antenna connectors to both

TX/RX connectors of the BTS. Table 1 shows the specification of the antenna.

Transport

10 Transport

Flexi Lite BTS uses IP/Ethernet as a standard transport protocol. Ethernet, both wireline

and fiber, is the standard interface in Flexi Lite BTS. Flexi Lite BTS provides various

transport options.

Wireline Ethernet

Flexi Lite BTS Base Module RJ45 socket supports 1 Gigabit Ethernet copper interface

100/1000 Base-T according IEEE802.3 clause 40.

Fiber Ethernet

Ethernet SFP interface (100 and 1000 Base-x) is based on MSA INF-8074 specification.

Both multi-mode and single-mode fibers are supported. Optional SFP modules are

available according to the different requirements in the actual site implementation. Fiber

SFP module options:

• 1000BASE-SX up to 550m

• 1000BASE–LX up to 10km

• 1000BASE-BX up to 40km

QoS-aware Ethernet switching allows cascading BTSs on the same site (collocation) or

across different sites (transport chaining) through electrical or optical Ethernet port.

Flexi Lite BTS can also provide the power to an external device if it meets the P+E power

supply requirements. Ethernet wireline interface supports power output P+E from Flexi

Lite BTS to external devices, for example microwave radio link. The voltage is -48V DC

with maximum 38 W power.

Note that P+E is a NSN proprietary power feeding solution over Ethernet. Standard PoE

(IEEE802.3at and IEEE802.3af) can be provided by an external power device.
