1 LOT A

1.1 General description

Lot A contains the equipment for secondary microwave network. The network has to be build because of the need for extending the Contracting Authority’s SFN DVB-T network. The Contracting Authority has decided to use radio-relay links with ethernet and E1 data interfaces. The secondary network is connected to the existing core network at the data layer.

The technical solution for Lot A must contain:

the appropriate radio relay equipment with corresponding antennas, relevant data interface on devices, management system to control the network elements of radio relay links from a separate, remote location equipment for redundant connectivity of signals in the case of 1 +1 and (1 +1) HSB configurations, equipment and solutions for "drop and continue" type of connectivity for E1 traffic at the transitional sites, upgradeability for future needs of the Contracting Authority.

Secondary network consists of mutually independent groups of radio relay links . The required total capacity of each hop is at least 80 Mbit/s and should be fully available to the Contracting Authority. The total capacity is divided into a part with at least 16 Mbit/s for the TDM (E1) traffic and a remaining part for the Ethernet data traffic. The Contracting Authority will upgrade the capacity in the following years to at least 100 Mbit/s by a software upgrade. Data speed on neither ethernet interface after the upgrade will exceed 100 Mbit/s.

The Bidder must provide all the elements and devices needed to meet the above requirements.

In the following years the Contracting Authority will extend the secondary microwave network to other locations.

1.2 Subject of procurement

The Contracting Authority will purchase 32 microwave hops with appropriate ethernet and E1 data interfaces for locations from 1.4.4 Location data.

The RF configurations of links used on each location are given in 1.4.3 Configurations of Radio RelayLinks .

Data interface configurations are described in Error: Reference source not found Error: Referencesource not found.

1.3 Link Calculation

1.3.1 Frequency Bands – RF ChannelsMicrowave links are planned for use in two different frequency bands:

7 GHz (7125-7425 MHz): channel arrangement as per ECC/REC/(02)06 - Digital Fixed Service Systems operating in the frequency range 7125-8500 MHz, (revised June 2007), Annex 1, The Band 7125-7425 MHz and 13 GHz (12750-13250 MHz): channel arrangements as per ERC/REC 12-02 - Channel arrangements for 12,75-13,25 GHz, (revised June 2007), Annex A, The Band 1275-1325 MHz;

The channel arrangement can be accessed on the website of the European Radiocommunications Office: www.erodocdb.dk.

The Bidder must offer the equipment which fully complies with the selected frequency arrangement, otherwise its tender will be excluded from further procurement process. The microwave links must operate without any problems in case the adjacent channel is occupied on the opposite polarization. The selected polarizations are given in chapter 1.3 Equipment configuration.

1.3.2 Offered equipment parameters

The Bidder must provide the technical parameters of the equipment in tabular form for the appropriate modulation type (32QAM?), with which a total bit rate of at least 100 Mbit/s is guarantied.

1.3.3 Microwave links performance calculations

After the selection of equipment and devices the Bidder make a link performance calculations.

The offer shall include link performance calculations of radio relay network all sections and comparison of the results with ITU-T and ITU-R recommendations.

The Bidder shall submit all the tables and results of calculations in paper and electronic form.In addition, it is required to calculate the unavailability of the following microwave chains:

KRVA-KALI-PEEC, PLES-MOZI-LUC1, KRIM-ORTN-KOCE, KUUK-TOLM-KAMB, SKAL-KUK-IDR2, KUK-GOBR-ANHO.

The calculations take account of the planned link configurations (1 +0, 1 +1 and 1 +1 HSB) and central frequencies of corresponding frequency bands as:

7 GHz : fc = 7275 MHz and for 13 GHz: fc = 12996 MHz.

Configurations of all connections are given in 1.3 Equipment configuration. The bidder shall do all performance calculations at a total bit rate of at least 100 Mbit/s. In this way the equipment is ready for the future.

The Bidders calculations must take into account:

the required availability of each microwave hop is 99,995 %, the appropriate modulation at the highest bit rate (32 QAM), the channel bandwidth of 28 MHz, asymmetrical RF coupling device at (1+1) HSB configurations, symmetrical RF coupling device at 1+1 configuration (SKAL-KUUK).

The individual results of the hop performance calculations must include at least the following:

output power at antenna port, type of antenna, which was included in the calculation, selected antenna gain, hop distance, free space loss, received power, fading margin, multipath fading in% and in min: sec / month predicted availability (rain) for the H - polarization, predicted availability (rain) for the V - polarization, calculated availability.

The Bidder must indicate the value of the used rainfall intensity in the calculations.

Radiation pattern of the used antennas must comply with ETSI 302217.

The Bidder which win the tender as the best one, will be required, after signing the contract to carry out the calculations of mutual interferences in the network. The calculation have to be done with nominal transmit power and at the final frequencies which will provide the Contracting Authority.




1.4 Equipment configuration

The network will be divided into seven independent group of links. The groups are made of a star or a chain configuration. Topology can be plotted from the locations coordinates. Equipment have to be configured separately for E1 and for IP transmission. The basic configuration is done at factory on the basis of the Contracting Authority requirements. Since the secondary network is independent from the existed core, the settings can be arbitrary.

Microwave network is intended for distribution of Contracting Authority signals. In most cases, the signal is transmitted in the direction from the center towards the end locations. The central point of a star is equivalent to an initial location in a chain configuration.

On this point the Contracting Authority signals enters/exits the secondary microwave network data layer, which deliver the signal to adjacent or end locations. On adjacent locations the Bidder must provide "drop and continue" mode of transmission. The same applies to ethernet traffic. If this functionality of cross connection is not provided within the equipment an additional device must be provided. The microwave network also carries two different IP traffic of the user. The equipment has to ensure the independence of traffic flows to the final locations. IP traffic for SFN DVB-T network will be transmitted within a VLAN. The Bidder shall provide a transparent transfer of users VLAN traffic from location to location.

Some links work in 1+1 and (1+1) HSB configurations. In that cases the Bidder shall provide redundant connections to the input output interfaces of the IDU. The bidder must take care also of the right configuration of the equipment.

The Contracting Authority sites are marked with four letter words. Here they are:

AJDO, ANHO, BIZL, BLDO, BRVG, CER1,CRN1, CRNO, GOBR, GRAH, IDR2, JEZ1, KALI, KAMB, KANI, KOCE, KRGO, KRIM, KRSK, KRVA, KUUK, KUUM, LAS1, LOKV, LUC1, MOZI, NANO, ORTN, PEEC, PLES, SELC, SEZA, SKAL, TOLM, TRB1, TVRH, TRZ1, VOGL, ZIR1, ZUZE.

The Bidder do the equipment setup and equipment labeling regarding to their real location. After the setup an labeling is finished, the equipment can be delivered to the Contracting Authority premises.
