Thebases are then installed according to the results of this study.1.1.1.1 CONNECTIONThe Alcatel-Lucent 4070 IO is designed for internal installation in the building, while theAlcatel-Lucent 4070 EO is designed for external installation.The 4070 EO IBS comes in a plastic box and is protected against temperature variation.The 2 antennae are outside the box so that they both have the same signal reception.Intelligent Base Stations (IBS) are fitted with a red LED that gives information about the stateof the Base Station:-Fixed LED:1. Software downloading2. Initialization phase, waiting for synchronization3. Software problem, IBS stopped.-Fast blink: There is a problem with the line.-Short ON, long OFF: Running on 1 UA link.-500ms OFF, 500ms ON: Running on 2 UA link.The IBSs can run and be powered remotely by the UA access (this is the most commonconfiguration). But they can also be powered by a power device. This is used when there are alot of IBSs and the system power cannot support all the connected IBSs.A base station may be connected to 1 or 2 UA links (UAI boards) and allows 3 or 6simultaneous connections with DECT/GAP terminals.The need for three or six communication channels depends on the number of cordless stationsand on the DECT traffic to be managed.In the event of a two-cable connection:-use two interfaces neighboring a UAI board-use the even-numbered interface for the master link and the other for the slave link.Both cables should have the same length. The first interface of the system’s UAI16 boardshould not be used since the operator station uses those points.1               1-1 1.1.1.2NUMBER OF USEFUL BASE STATIONSAny radio signal is subject to various propagation phenomena: attenuation, reflection anddiffraction. These phenomena are related to the environment of the Alcatel-Lucent 4070IO/EO, and affect the radio performance of the system.The effects can improve or deteriorate wave propagation.Take as an example a building with a metallic structure. A radio wave will tend to be subject tomany reflections which will consequently degrade system performance.Moreover, the range of an Alcatel-Lucent 4070 IO/EO is very dependent on the amount ofattenuation subjected to the radio wave across various zones.The following table gives the values of global coverage zone (cell) for an Alcatel-Lucent 4070IO/EO under normal environmental and topological conditions:Interior ExteriorCoverage area~ 50 m~ 400 mArea: ~ 7,000 m2~50000m21.1.1.3NUMBER OF USERS PER BASE STATIONType of Base Station connection.Number of DECT users3 channels46 channels121.1.1.4LOCATING DECT BASE STATIONSAs a result of the environment and the infrastructure, certain recommendations must be takeninto account for locating Alcatel-Lucent 4070 IO/EO:Chapter 1  !"1-2               Recommendations for locationPossible solutionsINTERIORCOVERAGE As far as possible from wallsSuspend Alcatel-Lucent 4070 IO/EO in aclear zoneDo not fix directly to a metallic structureMove Alcatel-Lucent 4070 IO/EO intoanother zoneDo not place in false ceilings or in telecomrooms Place Alcatel-Lucent 4070 IO/EO in usefulzones (corridors)As far as possible from industrial machinesor electrical cabinetsPlace 4070 IO/EO in useful zonesEXTERNALCOVERAGE Place the base stations in an open space(as far as possible from buildings)Attached to pylons for examplePlace the base stations higher than lowobstacles (trees, cars etc.)At the top of buildings on pylons forexample1.1.1.5 INTERACTIONSInteractions with other featuresIBS DECT and IBS PWT (Personal Wireless Telecommunications) cannot run together on thesame system. The first IBS plugged determines the system type (DECT or PWT).To switch from one system to another, unplug all IBSs, make a warm restart and plug in theIBSs.Interactions with other applicationsIBSs are fully compatible with other wireless technologies such as VOWLAN.Interactions with other software releasesOmniPCX Office release 5.1 requires 4 kinds of DECT initialization: Europe, Latin America,United-States and China. See also: § IBS CONFIGURATION .1.1.1.6 LIMITSNumber of IBSs: 20 IBSs per cabinet is recommended, however, the number of IBSs is onlyrestricted by the available power.DECT link limit: 3 links on an IBS with one UA access, 6 links on an IBS with 2 UA accesses.DECT handset limit: up to 120 handsets on a system.1.1.1.7PERFORMANCE AND QUALITYIBSs are downloaded during the system start phase or when hot plugged. A system with manyIBSs plugged might take longer to complete the start phase.Downloading 1 IBS takes about 30 seconds. It takes more time when several IBSs areplugged on the same UA resource.The end of restart is only possible after all the devices have been taken into account.If an IBS downloading fails, the IBS restarts with the previously installed software.1.1.1.8IBS CONFIGURATIONThere is no hardware configuration for IBS other than selecting between an external powersupply for each IBS and remote power by system.  !"             1-3 To configure the IBS software:ARI NumberThe ARI number identifies each OmniPCX Office.

Modifications should answer to specific needs.Line lengthThe Line length is the cable length used to plug the IBS to the system (distance between theIBS and OmniPCX Office). It enables the system to add a delay in signal and to avoid a shift inclock signal that creates a reset of the IBS.-1 In OMC,gotoUsers/Base stations List.-2 Select the IBS Master and click DetailsThere are 3 possibilities of configuration:-Short line (0-400 meters)Chapter 1  !"1-4               -Medium line (400-800 meters)-Long line (800-1200 meters)Restart the IBS after you have modified the Line length parameter.Antenna diversityAntenna diversity is the ability of the IBS to move the transmission and reception from oneantenna to the other so that the signal is always of the highest quality.Restart the IBS after you have modified the Antenna diversity parameter.Silent-Noisy IBSEnable the Silent-Noisy IBS parameter to set up the echo canceller device.The IBS is fitted with a software device that analyses audio signals and eliminates echo andnoises. This device is activated by default.When an IBS is deployed in a noisy environment, a lot of signals, including Speech ones, areeliminated while in Conversation state. This leads to bad Speech quality.You have the option to disable the echo canceller. In that way, the speech and the noisesignals are not filtered.

The SAR value for DECTsets (e.g.: Mobile Reflexes) is not significant.-Base station: the local SAR (head and chest) on 10g of body tissue for DECT basestations (e.g.: 4070) is lower than 0.5 W/kg (this is with an integrated omni-directionalantenna).1.1.2.2.2ANTENNAE CHARACTERISTICSIntegrated antennaeThe following is a list of characteristics for integrated antennae:-Bandwidth: 1.88 to 1.93 Ghz-Impedance: 50 Ohms-TOS: 1.5:1-Gain: 3 dBi (maximum)-Polarization: vertical (axis of the antenna)-Width of the beam at 3 dB (vertical): 90º-Radiation diagram: omni-directional in the horizontal plane.External antennaeAccording to the ETSI EN 301 406 standard, DECT antenna gain is limited to 12 dB +/-3dB. Inthe case of external directional antennae, if a minimum safety distance of 50 cm is respected,the SAR value is the same as the value obtained in the case of an integrated omni-directionalantenna (and therefore, lower than: 0.5 W/kg).1.1.2.2.3CONFORMANCE PERIMETER FOR EXPOSURE OF THE PUBLIC-Integrated omni-directional antennae: no limit for the conformance perimeter-External antenna (directional): the installation must allow for a safety perimeter respectinga minimum distance of 50 cm.1.1.2.3RECOMMENDATIONS FOR INSTALLATION1.1.2.3.1Standard Topology.The various building infrastructures are grouped into three types of geometric shape.  !"             1-9 Coverage areas SQUARE:Coverage areas RECTANGULAR:Coverage areas ROUNDThe distances quoted below give an idea of typical range of a base station.
