Introduction to the Nokia MetroSite EDGE Base Station 2 Introduction to the Nokia MetroSite EDGE Base Station This chapter describes the base station system (BSS) and the Nokia MetroSite EDGE Base Station generally. 2.1 Base station system In general terms, base stations perform the radio function for the base station system.
Product Description BTS Abis interface BSC Transmission BTS node Abis Abis Air interface interface interface BTS Abis interface Figure 1. 2.2 Base station system (BSS) Nokia MetroSite EDGE Base Station The Nokia MetroSite EDGE Base Station is a complete, all-climate base transceiver station. It can be used in 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.
Introduction to the Nokia MetroSite EDGE Base Station Figure 2. Nokia MetroSite - an ideal solution for dense, urban environment The Nokia MetroSite EDGE Base Station is the core element in the Nokia MetroSite Capacity Solution, which comprises complete sites equipped with BTSs, transmission equipment, and auxiliary equipment. However, the Nokia MetroSite EDGE Base Station can be integrated into other mobile network applications as well.
Product Description In order to ensure a high quality of calls, the Nokia MetroSite EDGE Base Station supports versatile features, such as frequency hopping. Due to its compact size, low weight, and high level of integration, 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.
Nokia MetroSite EDGE Base Station features 3 Nokia MetroSite EDGE Base Station features This chapter describes the technical properties of the Nokia MetroSite EDGE Base Station that contribute to: • Microcellular capacity • Network quality • Data services • Deployment • Operation and maintenance A description of the advanced telecommunication features is also presented here.
Product Description The dual band feature enables the operator to configure any sector to operate either on a 900 or 1800 MHz frequency, thus increasing the capacity of the network. With CX 3.2 software, or later, the 800/1800 MHz and 800/1900 MHz dual band frequencies are also possible. More information on the coverage areas created with different sectoring options can be found in Section 4.1 in this document.
Nokia MetroSite EDGE Base Station features 3.1.3 RF power and sensitivity for microcellular applications The RF performance of the Nokia MetroSite EDGE Base Station is suitable for microcellular, building infill and roadside coverage applications. The maximum RF power of the Nokia MetroSite EDGE Base Station transmitter is 5 W at the antenna connector. The maximum RF power of the Nokia MetroSite EDGE Base Station in EDGE modulation mode is 3.2 W. The RX sensitivity is better than 106 dBm.
Product Description Multipath propagation of the radio signal may cause local variations of signal strength. Deep fades, particularly when the mobile station is near a cell border, reduce the quality of the received signal. To minimise this effect, a spatial or polarisation receiver diversity can be used, which means that two different paths are used for the received signals.
Nokia MetroSite EDGE Base Station features When the Nokia MetroSite EDGE Base Station itself is installed inside a building, the antennas can be located outdoors. The size of antenna feeders, 1/4” and 3/8”, support the flexibility of installation. The TRX test includes an antenna cable detection feature which, in most of the cases, verifies whether the cable connection between the TRX and the antenna is free of faults. 3.
Product Description 3.3.1 General Packet Radio Service (GPRS) 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 set-up for sending a data packet. The throughput is as high as in high speed circuit switched data (HSCSD). The Nokia MetroSite EDGE Base Station supports GPRS coding schemes 1 and 2. 3.3.
Nokia MetroSite EDGE Base Station features After unpacking the delivery, some of the units can be removed from the BTS to make it easier to handle. Usually, removing only the TRXs makes the Nokia MetroSite EDGE Base Station light enough to handle. The Nokia MetroSite EDGE Base Station is then installed on a wall or a pole. In wall mountings, the packing cardboard can be used as a template for drilling the anchor screw holes to the wall.
Product Description Figure 3.
Nokia MetroSite EDGE Base Station features 3.5 Advanced operation and maintenance The features concerning the operation and maintenance (O&M) of the Nokia MetroSite EDGE Base Station are described in this section. During operation, the Nokia MetroSite EDGE Base Station is managed remotely from the OSS. Site visits to carry out routine O&M tasks are not usually needed. 3.5.1 Integration of TRX and base control functions (BCF) One of the TRXs is configured as the master TRX of the BTS.
Product Description The TRX test covers all functions between the Abis and Air interfaces: digital and RF parts, antenna cable detection, RX sensitivity, and TX level. The main reason for providing a single multipurpose test is to minimise the total test time; once the time slot is reserved for testing, the test time is used effectively. The test utilises the multifunctional RF loop and it is automatically performed for both RX branches. The test time is approximately 15 seconds.
Nokia MetroSite EDGE Base Station features The BTS has a cooling fan and built-in heaters to provide a smooth temperature controlling facility. The BTS software controls the heating and cooling to provide operation conditions which are as stable as possible. Heating and cooling are adjusted gradually to ensure low temperature gradients and noise levels. The temperature is continuously monitored with sensors placed on active units.

Applications 4 Applications This chapter describes the typical applications of the Nokia MetroSite EDGE Base Station including the transmission alternatives. 4.1 Building capacity with the Nokia MetroSite EDGE Base Station The Nokia MetroSite EDGE Base Station can be used for building capacity in areas of heavy telecommunication traffic, such as for building infill, street corners, sports arenas, shopping centres, and underground stations.
Product Description Efficient frequency re-use requires that the size of the coverage area (cell) be limited. Figure 6 shows how the buildings surrounding the Nokia MetroSite EDGE Base Station can be used to limit the cell size and shape in an urban environment. BTS BTS Figure 6. Microcells built with the Nokia MetroSite EDGE Base Station The Nokia MetroSite EDGE Base Station can be sectored freely.
Applications TRXs from different sectors can be connected to one antenna. The following examples assume that the MetroSite antenna is used; the diversity applications may differ from the ones presented here if different antenna types are used. Figure 7 presents a single band (GSM/EDGE 900) BTS which has four TRXs in one sector. The antennas are directed to the same direction; the resulting coverage area comprises four TRXs.
Product Description Figure 8 shows schematically the coverage areas created with a BTS that has four sectors (two GSM/EDGE 900 sectors and two GSM/EDGE 1800 sectors) in a (1+1)/(1+1) configuration. In Figure 8 , one GSM/EDGE 900 and one GSM/EDGE 1800 sector are connected to each antenna. The antennas are directed to different directions.

Product Description Furthermore, the Nokia MetroSite EDGE Base Station can be directly connected to the BSC. The Nokia MetroSite EDGE Base Station supports 16 Kbit/s, 32 Kbit/s and 64 Kbit/s Abis TRX signalling. The O&M signalling speed alternatives are 16 Kbit/s, 32 Kbit/s and 64 Kbit/s. To optimise the use of transmission capacity, combined O&M and TRX signalling is also supported at all these speeds. Locally, the transmission configuration is managed with the Nokia MetroSite BTS Manager.
Nokia MetroSite EDGE Base Station related software 5 Nokia MetroSite EDGE Base Station related software This chapter describes the Nokia MetroSite EDGE Base Station software (SW) and the Nokia MetroSite BTS Manager software. Generally, the Nokia MetroSite EDGE Base Station is managed remotely from the OSS via the BSC. The management tasks carried out on site are kept to a minimum. On site, the Nokia MetroSite BTS Manager is used for BTS management.
Product Description The BTS start-up procedure has been optimised to shorten the boot-up time. No time-consuming tests are done during the BTS start-up, which contributes to rapid deployment of the BTS and shorter breaks in service after power failures. Alarms generated by the Nokia MetroSite EDGE Base Station are radically reduced by advanced diagnostics and alarm management. Only the unit level and BTS level alarms are sent to the BSC.
Nokia MetroSite EDGE Base Station related software Figure 11. Nokia MetroSite BTS Manager desktop Note Nokia MetroSite BTS Manager is part of the Nokia SiteWizard SW package. 5.3 BTS software updates When the Nokia MetroSite EDGE Base Station software is updated, it can be loaded either locally with the Nokia MetroSite BTS Manager, or remotely from the BSC or the OSS (via the BSC).
Product Description The BTS SW is loaded to the master TRX which in turn updates the software in the slave TRXs. When new TRXs are added for more capacity, or when TRXs are replaced for maintenance reasons, the master TRX updates the software in the new slave TRXs if their software version is different from the master TRX SW. The Nokia MetroSite EDGE Base Station software can be downloaded as a background operation without interrupting the BTS operation.
