Introduction to Nokia MetroSite EDGE Base Station

2 Introduction to Nokia MetroSite EDGE Base Station

The Nokia MetroSite EDGE Base Station is an all-climate BTS available for GSM 900, 1800 and 1900 and GSM/EDGE 800, 900, 1800 and 1900 systems, or as a dual band GSM 900/1800 or dual band GSM/EDGE 900/1800, 800/1800 or 800/1900 BTS. MetroSite EDGE BTS can contain between one and four transceivers (TRXs) in Omni or sectored configuration and by chaining cabinets up to 12 transceivers in three cabinets.



Figure 1. The Nokia MetroSite EDGE Base Station is an ideal solution for a dense urban environment

2.1 High voice and data capacity

The Nokia MetroSite EDGE Base Station is used for microcellular, building infill, and roadside coverage. With the MetroSite EDGE Base Station, indoor coverage can be provided from outdoors or by using DAS (distributed antenna systems).

Introduction to Nokia MetroSite EDGE Base Station

The Nokia MetroSite EDGE Base Station provides a number of advanced telecommunication features for both voice and data. To ensure efficient data traffic, EDGE (Enhanced Data Rates for Global Evolution) functionality is provided.

Despite the small size of the Nokia MetroSite EDGE Base Station cabinet, it can accommodate up to four TRXs. This, together with efficient frequency re-use, makes Nokia MetroSite EDGE base stations a very effective solution for building up mobile network capacity in areas of heavy telecommunication traffic. The Nokia MetroSite EDGE Base Station is available with 5W and 13W GSM/EDGE TRXs.

In order to ensure the high quality of calls, the Nokia MetroSite EDGE Base Station supports versatile features such as 900/1800, 800/1800 or 800/1900 dual band, frequency hopping, and receiver diversity.

As the base station is located close to antennas, low antenna line loss is achieved.

2.2 Fast and easy implementation

Due to its small size and weight, the Nokia MetroSite EDGE Base Station is fast and easy to install either indoors or outdoors with minimal preparations. Both wall and pole installations are supported. From the network planning point of view, the Nokia MetroSite EDGE Base Station can be installed at optimal locations.

In addition to these versatile and advanced properties, the Nokia MetroSite EDGE Base Station has also been designed for easy commissioning. This is achieved by auto detection of the base station hardware, implementation of the Site Configuration File (SCF), and the easy-to-use Nokia SiteWizard commissioning tool.

The low power consumption and low heat load give freedom in installation and offer a possibility to long back up times.

2.3 Cost savings and immediate revenue flow

The size and ease of deployment of the Nokia MetroSite EDGE Base Station significantly reduce the operator’s site planning and site acquisition costs. The small size and unobtrusive appearance of the BTS enable totally new types of BTS sites and mass site acquisition.

Fast start-up and quick integration into the network enable immediate revenue flow to the operator. Furthermore, the operational costs are low because base station management is carried out remotely from the



Operational Support System (OSS). During upgrade operations, the smooth step-by-step expansion keeps the revenue flow uninterrupted and increases the operator’s profit.

Features

3 Features As well as all the normal base station features, the Nokia MetroSite EDGE Base Station has many other unique features. This chapter describes these features in more detail.

3.1 High voice and data capacity

With the Nokia MetroSite EDGE Base Station, the operator can increase telecommunication capacity whilst simultaneously maintaining the high quality of calls.

3.1.1 Smooth capacity expansion

A Nokia MetroSite EDGE Base Station cabinet accommodates up to four TRXs. There is no need to install all TRXs in the cabinet, even if there is an anticipated requirement for the capacity of four TRXs at a later phase. In this case, the site could be prepared with all the necessary antennas and antenna feeders from the onset and, as the demand for capacity grows, additional TRXs can be installed to the BTS during operation without interrupting the base station service. In future, capacity can be further increased by chaining up to three Nokia MetroSite EDGE Base Stations (including up to 12 TRXs) together as one Base Control Function (BCF) object.

3.1.2 Dual band

The Nokia MetroSite EDGE Base Station supports dual band operation. There are no limitations to the combinations of GSM or GSM/EDGE TRXs in the Nokia MetroSite EDGE Base Station. Any cell can be configured to operate either on 900 or 1800 MHz, 800 or 1800 MHz, or



800 or 1900 MHz. Therefore, the network capacity can be increased by the addition of a new frequency band. This feature not only increases capacity, but also helps to maintain the high quality of calls.

3.1.3 Optimised RF features

The Nokia MetroSite EDGE Base Station can be utilised for building up full coverage, such as for infill sites or roadside coverage. It also provides capacity for many indoor applications, since it can be used together with DAS, or it can provide indoor coverage from outdoors.

The output power and the receiver sensitivity of the Nokia MetroSite EDGE Base Station facilitate efficient frequency re-use with minimal interference. The Nokia MetroSite EDGE Base Station with two or more TRXs in the same sector can be configured to use frequency hopping and receiver diversity. These features add to the quality of calls going through the Nokia MetroSite EDGE Base Station.

3.1.4 More speed and capacity with EDGE

Nokia MetroSite provides a smooth entry to the high data rate solution. GSM and GSM/EDGE TRXs can coexist in the same BTS cabinet, or all TRXs can be GSM/EDGE capable.

3.1.5 Integrated transmission for microcellular access

The flexible radio transmission solution of the Nokia MetroSite EDGE, using the 58 GHz Nokia MetroHopper Radio for last-kilometre access, together with the other BTS features, allows for a very large number of BTSs to be installed in a small area. For more information on the radio transmission solution, see the Nokia MetroHopper Radio Product Overview.

3.1.6 External battery backup with Flatpack Outdoor power system 3kW/48V

To ensure an uninterrupted power supply for the Nokia MetroSite EDGE Base Station, battery backup can be provided externally by Flatpack Outdoor power system 3kW/48V. Flatpack Outdoor power system 3kW/48V is a fan-cooled cabinet with a filter unit. Dimensions are W x D x H 590 x 427 x 775 mm with a weight of approximately 110 kg with batteries. An empty cabinet weighs approximately 30 kg. Operating

Features

temperature range is from -33 to +50º C. The cabinet can be installed on the wall, on a pole or on the floor. Operating voltage covers a wide range, 85…310VAC (single phase) with a limited output power between 85…185VAC. Maximum output power is 3kW from 2 x 1500W rectifiers.

3.1.7 Antenna solution

The Nokia MetroSite EDGE Base Station has versatile antenna configuration options. External antennas are used and, in certain configurations, external combiners may be used. Nokia MetroSite antennas comprise multiport, directional and omnidirectional antennas.

Nokia MetroSite EDGE Base Station antennas support dual band operation. They are physically unobtrusive and blend easily into the city environment. Other antennas, such as single and dual band antennas, cross-polarised antennas, and DAS (distributed antenna systems) can also be used for indoor coverage with the Nokia MetroSite EDGE Base Station.

3.1.8 Telecommunications

Nokia MetroSite EDGE Base Station software supports all essential basic telecommunication features. These features are described in detail below.

3.1.8.1 Half Rate speech coding

The use of half-rate (HR) speech coding makes it possible to almost double the amount of available traffic channels on the radio path. This is achieved with the existing transmission lines on the Abis interface. Half-rate coding enables the use of 8 Kbit/s channels.

3.1.8.2 Enhanced Full-rate speech coding

Enhanced full rate (EFR) speech coding improves the voice quality in all channel conditions. The coding is based on improvements made for half-rate coding applied to the existing GSM full rate channel coding.

3.1.8.3 Support for data services

• HSCSD (High Speed Circuit Switched Data) - This feature provides accelerated data rates for the end-user applications, such as browsing the Internet, file transfer, and facsimile.

• 14.4 Kbit/s GSM data services- This feature provides accelerated user data rates at 14.4 Kbit/s level. This feature can be combined with HSCSD.



• Non-transparent and transparent data (9600, 4800, 2400 bit/s) – Non-transparent means that the data rate can be changed automatically during the call (due to increased traffic, for example). Transparent data uses a fixed data rate throughout the duration of a call.

3.1.8.4 GPRS (General Packet Radio Service)

GPRS is designed to make the GSM data services more compatible with LAN, WAN, and the Internet. In GPRS, the radio resources are used only when there actually is data to be sent or received. GPRS also provides immediate connectivity and very short setup for sending a data packet. The throughput is as high as in high-speed circuit switched data (HSCSD). Nokia MetroSite EDGE BTS supports GPRS coding schemes 1, 2, 3 and 4.

3.1.8.5 EGPRS (Enhanced General Packet Radio Service)

EGPRS is built on top of GPRS to increase the data rate of GPRS by applying EDGE modulation and increasing the Air interface throughput. The data rate of GPRS is increased up to threefold with EGPRS. Nokia MetroSite EDGE BTS supports EGPRS modulation and coding schemes (MCS) 1 to 9. EGPRS requires EDGE capable TRXs to be fitted in the BTS.

3.1.8.6 Adaptive Multi Rate Codec (AMR)

Adaptive Multi Rate Codec (AMR) introduces a set of codecs and adaptive algorithm for codec changes and can provide significantly better speech quality and more capacity.

3.1.9 Multi BCF for MetroSite BTS

Multi BCF Control feature allowed the combination of several BTSs into one logical cell, allowing the operator to increase the capacity of a cell while maintaining the maximum spectral efficiency. The new Multi BCF for MetroSite BTS feature enables up to three MetroSite cabinets to be connected to one TalkFamily BTS. The maximum number of TRXs with this combination can be 24 (12 TRXs Talk cabinet and 12 TRXs using three chained Metro cabinets). The Multi BCF for MetroSite BTS enables the Multi BCF to provide a path for site expansion from Nokia TalkFamily to Nokia Metro and UltraSite EDGE BTSs and thus an evolution path to EDGE services.

The operator can arrange base stations so that the TRXs in different base stations, operating on the same frequency band, can serve the same cell with a single BCCH. At the base station site, the operator makes some installations, for example synchronisation between the

3.2 Fast and easy implementation

3.2.1 Installation

Because of its small size, light weight, and high level of integration, the Nokia MetroSite EDGE Base Station is easy to transport and install.



Due to its small and modular structure, installation can be carried out in stages by one person. The BTS chassis, which is the heaviest single part, weighing 8 kg, can be installed separately. After this, the plug-in units and the cover can be installed one by one. If sufficient lifting equipment is available on the site, and if other circumstances are favourable, the BTS can also be mounted without removing any of the units.

The Nokia MetroSite EDGE Base Station can be installed either on a wall or on a pole. For pole installations, an optional pole mounting kit is available. This kit can be used with a variety of pole thicknesses.

The Nokia MetroSite EDGE Base Station can also be mounted horizontally on its back, extending the number of installation locations.

The Nokia MetroSite EDGE Base Station cabinet’s internal cabling is limited to diversity cables. Also, external cabling has been reduced to a minimum.

3.2.2 Commissioning

Commissioning the Nokia MetroSite EDGE Base Station has been made easy. No external measuring devices are needed for the BTS’s commissioning tests. The Nokia SiteWizard commissioning software tool guides the user through the whole commissioning process.

Nokia MetroSite EDGE Base Station software includes an auto detection feature which identifies the BTS hardware. This reduces the time spent on commissioning as the user does not have to manually enter a separate HW database for the BTS.

At the end of the commissioning process, a Site Acceptance Report is produced automatically by Nokia SiteWizard.

3.3 Cost savings and immediate revenue flow

Since the installation of the Nokia MetroSite EDGE Base Station does not require extensive site planning, the site planning costs can be reduced. The versatile installation options also ease the process of site acquisition and help to reduce the operator’s site rental costs. Possible installation locations for the Nokia MetroSite EDGE Base Station can be found on almost every street corner in any city. Banks, restaurants, billboards, or other such premises and structures enable affordable mass site acquisition.

Installing and commissioning the Nokia MetroSite EDGE Base Station is fast and easy. The small size and light weight allow the installation to be carried out with only a minimal workforce. Because of the fast commissioning and integration to the network, the ease of handling of the equipment and the minimised cabling of the site, the time spent on the installation site is reduced. The easy commissioning and quick integration into the network ensure that the Nokia MetroSite EDGE Base Station is up and running very soon after installation. This means that



the installation costs are kept to a minimum and the revenue flow starts immediately.

During operation, the Nokia MetroSite EDGE Base Station is managed remotely from the OSS. Site visits are not needed for routine O&M tasks.

Applications and configurations

4 Applications and configurations 4.1 Applications

The Nokia MetroSite EDGE Base Station is designed to meet the demands of constantly increasing mobile telecommunication traffic. As well as the base station, the Nokia MetroSite Capacity Solution comprises fully equipped sites with transmission and auxiliary equipment.

Optimised RF performance, high capacity, compatibility with Nokia Soft Capacity Solution features, and versatile installation options make the Nokia MetroSite EDGE Base Station an ideal solution for areas where high capacity is needed.

In special capacity hotspots - such as street corners in downtown areas, sports arenas, shopping centres, underground stations, and office buildings - the Nokia MetroSite EDGE Base Station provides virtually unlimited capacity.

The Nokia MetroSite EDGE Base Station can also be used to provide coverage for macro cellular networks - like gaps in the network or unfriendly-terrain roadside sites. It can be used to build fill-in coverage in dense urban area where the site locations for conventional base stations are hard to find or a quick rollout is needed.

When installing the MetroSite EDGE BTS next to the antennas, such as on a mast head, it provides similar coverage to a macro-BTS, but with minimal costs, as long feeder lines and traditional site constructions such as shelters can be ignored.



Figure 4. Roadside coverage with the Nokia MetroSite EDGE Base Station

Furthermore, the Nokia MetroSite EDGE Base Station is an ideal solution for indoor applications with high traffic intensity - such as airports, railway stations, tunnels, shopping malls, hall-type areas, and large offices. In these cases, the Nokia MetroSite EDGE Base Station can be used as a stand-alone base station, or as part of a distributed antenna system (DAS).

In a stand-alone base station installation, the BTS can be located, for example, on the wall of a building opposite to a location where indoor coverage is being built, with the antennas directed towards that location. In DAS applications built with the Nokia MetroSite EDGE Base Station, indoor antennas and/or radiating cables can be used.

Figure 5. Microcells built with Nokia MetroSite EDGE base stations

Efficient frequency re-use requires the size of the coverage area (cell) to be limited. The figure above shows how the buildings surrounding Nokia MetroSite EDGE BTS and antennas can be used to limit the cell size and shape in an urban environment.

4.2 Configurations

The Nokia MetroSite EDGE Base Station can accommodate up to four TRXs, which can be used in any single or multi-sectored configuration, each containing from one to four TRXs.



Sectoring for the Nokia MetroSite EDGE Base Station is very flexible. Each TRX has its own antenna connector. The TRX incorporates a duplex filter, and one antenna therefore handles both transmit and receive functions. As every TRX can form a sector of its own, the maximum number of sectors for a single BTS is four.

The Nokia MetroSite EDGE Base Station can be upgraded during operation from one TRX per BTS to four TRXs per BTS. It is also possible to chain up to three BTSs together, including up to 12 TRXs in max 6 sectors.

4.2.1 Dual band

The configuration of the Nokia MetroSite EDGE Base Station is very flexible. The introduction of the GSM or GSM/EDGE 900/1800, 800/1800, or 800/1900 dual band configuration is easy due to the fact that the BTS cabinet can simultaneously house 900 and 1800, 800 and 1800, or 800 and 1900 MHz TRXs.

4.2.2 EDGE

When there is a need for new data services in the microcell network, an upgrade to EDGE is easy since GSM and GSM/EDGE TRXs can coexist in the Nokia MetroSite EDGE Base Station. GSM/EDGE TRXs can provide both speech and data services. In mixed configurations, there are no limitations concerning how the different TRXs can be combined. However, in the case that the MetroSite EDGE BTS has both GSM and GSM/EDGE TRXs, GPRS and EGPRS must be activated in the GSM/EDGE TRXs only.

Management and software

5 Management and software 5.1 OSS/NetAct and BSC software

OSS/NetAct software manages the entire GSM/EDGE network, including the BTS, using the BSC. This remote software minimises the need for onsite BTS management. OSS/NetAct software incorporates a full range of functions — from fault, performance and configuration management to transmission, trouble, and security management.

Software updates are delivered via Nokia Online Services (NOLS).

For more information, see OSS/NetAct documentation.

5.2 BTS software

The BTS can store two software packages in its non-volatile memory. The software can be loaded to the BTS either locally from the Nokia BTS Manager or remotely from the BSC or NetAct. The software packages are loaded to the non-volatile memory of each TRX.

The BSC updates the BTS SW packages if they are different from the BSC software. After downloading, new software is activated by reset and the initialisation takes approximately one minute. The BTS and its units can be reset separately for testing purposes, locally with the Nokia BTS Manager and remotely from the BSC or the NetAct.

The BTS startup procedure has been optimised to shorten the bootup time. No time-consuming tests are done during the BTS startup, which contributes to rapid deployment of the BTS and shorter breaks in service after power failures.

Alarms generated by the BTS are radically reduced by advanced diagnostics and alarm management. Only the unit level and BTS level alarms are sent to the BSC. Correlation rules and fault diagnostic



procedures ensure that the appropriate recovery procedure is activated automatically. The fault diagnostics make it possible to locate a fault to a specific unit of the BTS or to a specific part of the BTS system.

5.3 Nokia SiteWizard

Nokia SiteWizard software is used for managing the Nokia MetroSite EDGE Base Station and its transmission equipment, including radio links. Nokia BTS Manager (which is part of Nokia SiteWizard) is primarily used to commission the base station and to carry out maintenance tasks locally. During normal operation, the Nokia MetroSite EDGE Base Station is managed remotely from the OSS.

Nokia SiteWizard eases the process of BTS commissioning. It provides a graphical user interface and runs in Windows 2000 or Windows XP.

The SiteWizard’s context-sensitive on-line Help gives the user information on the user interface elements and tasks performed with the Nokia SiteWizard.

The Nokia BTS Manager (SiteWizard) desktop Figure shows an example of the Nokia BTS Manager (SiteWizard) desktop with the following windows open:

• Supervision - Equipment View window

• BTS Events window

• Alarms window

Management and software

Figure 6. Nokia BTS Manager (SiteWizard) desktop

5.3.1 Autodetection of BTS configuration

Nokia MetroSite EDGE Base Station software includes an auto detection feature which automatically identifies the type, version, and serial number of the BTS units. This information is stored in the non-volatile memory of the master TRX and the data is backed up to the slave TRXs. If new units are added to the BTS or old units are replaced, the information is automatically updated.



5.3.2 Advanced BTS diagnostics and alarm management

The Nokia MetroSite EDGE Base Station features an advanced BTS diagnostics system that considerably reduces the number of alarms. The relevant alarm information is easily accessible and understandable.

5.3.3 Combined O&M and telecommunication signalling

The O&M signalling and TRX signalling can be combined into one channel to optimise the use of transmission capacity.

5.3.4 Chaining of Nokia MetroSite EDGE base stations

By extending the BTS’s internal databus, between five and 12 TRXs can be chained together, divided over two to three BTS cabinets. In BTS chaining, the first BTS handles transmission and is the master BTS.

5.4 Software updates

The Nokia MetroSite EDGE Base Station can store two software packages in its memory. The software can be loaded:

• Locally with Nokia SiteWizard

• Remotely from the BSC or OSS (via the BSC)

The BTS software can be downloaded as a background operation without interrupting the operation of the BTS. The activation of new software can be done at any time convenient for the operator.

Constructions and units

6 Constructions and units As with the other properties of the Nokia MetroSite EDGE Base Station, its construction has been optimised for microcellular, building infill, and roadside coverage. The chassis and the units are easy to handle and install. The compact structure allows installation in previously inaccessible locations. Because of its plug-in construction, the Nokia MetroSite EDGE Base Station provides greater flexibility than any other microcellular base station currently on the market.

6.1 Mechanics

The Nokia MetroSite EDGE Base Station features a lightweight aluminium chassis with a stainless steel sheet back plate. A separate two-tone plastic cover (coloured light grey NCS-S-2500-N and grey NCS-S-1500-N) covers the chassis and the plug-in units. If needed, this standard cover can be painted to make it blend in better with the surrounding environment. The cover shields the base station against ingress of water, snow, and foreign objects. The chassis and units are protected by EMC shielding.

6.2.2 Interface unit

The external interfaces of the Nokia MetroSite EDGE Base Station are located on the interface unit. The local management port (LMP) provides the connection to the Nokia SiteWizard PC. The Nokia Q1 interface is a connection for supervising Nokia Q1-bus compatible external equipment, such as Nokia Hopper radios. The extension interface is used as a databus for BTS chaining. Furthermore, the interface unit provides a connection for customer-definable external alarms (10) and controls (4).

The interface unit also provides the BTS master clock.

6.2.3 Transmission unit

The transmission unit takes care of the transmission between the Nokia MetroSite EDGE Base Station and the BSC through the Abis interface. The transmission media can be either a radio link or a wire line (E1/T1). The transmission unit interconnects the Nokia MetroSite EDGE Base Station and the BSC using point-to-point, star, or loop network configurations. The Nokia MetroSite EDGE Base Station supports 16 Kbit/s, 32 Kbit/s and 64 Kbit/s Abis TRX signalling. Similarly, the O&M signalling speed can be 16 Kbit/s, 32 Kbit/s, or 64 Kbit/s.

Locally, the transmission configuration is managed with the Nokia SiteWizard.

The following radio link transmission interface units are available for Nokia MetroSite EDGE Base Stations:

• FXC RRI: 16 x 2 Mbit/s, support for two microwave radio outdoor units (two Flexbus connectors), grooming, branching, loop and HSB protection support, cross-connection at 8 Kbit/s level



The FXC RRI transmission unit is connected to the Nokia MetroHopper Radio or the Nokia FlexiHopper Microwave Radio with a coaxial cable referred to as Flexbus. Moreover, with the Flexbus, it is possible to connect RRI transmission units to each other.

The FXC RRI transmission units interconnect the Nokia MetroSite EDGE Base Station and the BSC using point-to-point, chain, star, or loop network configurations.

The following wire line transmission units are available for the Nokia MetroSite EDGE Base Station:

• FC E1/T1: 1 x 2 Mbit/s (E1) or 1 x 1.5 Mbit/s (T1) PCM connection, one coaxial 75 ohm TX and one coaxial 75 ohm RX connector for E1 use, one twisted pair 120/100 ohm TX/RX interface connector for either E1 or T1 use.

• FXC E1: 4 x 2 Mbit/s (E1) PCM connections, four coaxial 75 ohm TX and four coaxial 75 ohm RX connectors for E1 use, grooming, branching and loop protection support, cross-connection down to 8 Kbit/s level

• FXC E1/T1: 4 x 2 Mbit/s (E1) or 4 x 1.5 Mbit/s (T1) PCM connections, four twisted pair 120/100 ohm TX/RX interface connectors for either E1 or T1 use, grooming, branching and loop protection support, cross- connection down to 8 Kbit/s level.

The FC E1/T1 operates as the termination point in a star or chain topology network. The FXC E1 and FXC E1/T1 transmission units interconnect the Nokia MetroSite EDGE Base Station and the BSC using point-to-point, chain, star, or loop network configurations.

The following optical transmission unit is also available for Nokia MetroSite EDGE BTS:

• FC STM-1 unit enables cross-connection between PDH (Plesiochronous Digital Hierarchy) and SDH (Synchronous Digital Hierarchy) transmission rates. The unit is a complete SDH STM-1 Terminal Multiplexer (TM) or Add/Drop Multiplexer (ADM) inside Nokia base stations.

If more transmission capacity is needed, the Nokia MetroHub Transmission Node can be used with Nokia MetroSite EDGE Base Station (for more information, see the Nokia MetroHub Transmission Node Product Overview).

6.2.4 Power supply unit

The purpose of the power supply unit is to produce the supply voltages needed by the Nokia MetroSite EDGE Base Station. The base station


supports both AC and DC power. DC power supply is reverse-polarity protected.

The power consumption of the Nokia MetroSite EDGE Base Station depends mainly on the BTS configuration, the number of TRX units in use, and the transmission mode. The power consumption of the TRX depends on the transmitting output power and whether the modulation is GMSK or 8-PSK and the traffic load. The Nokia MetroSite EDGE Base Station provides the power feed to the radio units and is capable of feeding power to up to two Nokia FlexiHopper Microwave Radio outdoor units.

The power supply unit alternatives are listed in the Nokia MetroSite EDGE Base Station power supply unit alternatives table.

Input voltage PSU type

110 – 230 VAC CVSB

-48 VDC/+24 VDC CVSD

6.2.5 Fan unit

The fan unit is located at the bottom of the cabinet. The master TRX controls the fan unit according to the temperature information from other units. The fan unit has 16 speeds and as more cooling is required the speed increases. The adjustable speed also minimises the noise generated by the fan unit.

Heat load generated by the BTS is affected by transmitted output power, amount of TRXs, transmission card type and the used modulation type. The same fan is used in all MetroSite EDGE Base Station configurations.

8.3.5 Base station interface equipment

The following standards and recommendations relate to base station interface equipment.


Note that these recommendations are related to the transmission environment and the BTS transmission equipment complies with them. However, because the transmission equipment is used as a part of BSS, there is a special (stricter) requirement for the BSS synchronization.

To meet the BTS Air interface accuracy requirement 0.05 ppm (set by ETSI), the Abis interface must meet the long-term accuracy of 0.015 ppm. This kind of accuracy is attained if the network master clock (PRC) fulfills the ITU-T recommendation G.811 and the synchronization of the network is correct. The maximum jitter/wander of the Abis interface is specified in the ITU-T recommendation G.823.

Another possibility is that the source for BTS master clock reference is an external 2.048 MHz clock signal. In that case, the FXC unit is configured so that the fourth interface is not used for 2.048 Mbit/s traffic, but as a 2.048 MHz synchronization input. The Abis accuracy requirement above applies also for the FXC synchronization input interface.
