One port is used to receive and transmit signals while the other is used to receive signals only. The RX channel functions as follows: 1. Antennas of the two-port antenna system receive weak signals from UEs and send them to the MAFU through feeders. 2.

Disadvantages of star topology: Compared with the other networking modes, star topology requires more transmission resources.14.2 Chain Topology Chain topology applies to the belt-shaped and loosely populated areas, such as highways and railways.14-2 Huawei Technologies Proprietary Issue 04 (2007-06-30)

Figure 14-4 shows the topology. Figure 14-4 Topology of the BTS3812E/BTS3812A cascaded with RRUs Advantages : This topology can reduce costs in initial construction and expand the network coverage. The RRUs feature convenience in network planning and centralized management by the upper-level NodeB. Disadvantages: Faults in the upper-level NodeB may affect normal operations of RRUs.14.5 2G/3G Concurrent Transmission The NodeB supports the fractional ATM and CES, which enables 2G/3G concurrent transmission and reduces investment on transmission resources.14-4 Huawei Technologies Proprietary Issue 04 (2007-06-30)
  • BTS3812E and BTS3812AProduct Description 14 Topologies of the BTS3812E/BTS3812AFractional ATM In the fractional ATM mode, some of the 32 timeslots in an E1/T1 link are used for ATM cell transmission. That is, the ATM cells are mapped to some of the 30 timeslots (timeslots 0 and 16 already reserved) at the TX end and then recovered from those timeslots at the RX end. The scenarios of 2G/3G co-transmission in fractional ATM mode are as follows: l The operators have GSM mobile networks. It is possible to use current transmission network resources to build 3G networks. l The RNC and NodeB support the fractional ATM. l The function of timeslot cross connection is provided by the BSC and BTS or external timeslot cross devices. Figure 14-5 shows the 2G/3G co-transmission in Fractional ATM mode. Figure 14-5 2G/3G co-transmission in fractional ATM mode Advantages: 2G/3G co-transmission helps operators speed up WCDMA construction and offering services. It saves the transmission resources and reduces expenses in the initial phase of WCDMA construction. Disadvantages: The 3G equipment is dependent on the 2G equipment, whose upgrade affects the stability of 3G services.CES The Circuit Emulation Service (CES) uses the technology that emulates the TDM circuit in the ATM network. The CES enables the narrowband signals to be transmitted in the wideband system. In CES mode, 2G systems may use the 3G ATM transmission devices to transmit 2G services. The scenarios of 2G/3G co-transmission in CES ATM mode are as follows: l When the transmission resources of the 2G network are insufficient, 2G systems can use the ATM transmission devices to transmit services through CES mode. l The RNC and NodeB must support the CES. Figure 14-6 shows the 2G/3G co-transmission in CES mode.Issue 04 (2007-06-30) Huawei Technologies Proprietary 14-5
  • BTS3812E and BTS3812A14 Topologies of the BTS3812E/BTS3812A Product Description Figure 14-6 2G/3G co-transmission in CES mode Advantages of CES mode: l 2G/3G co-transmission in CES mode reduces costs of transmission and network maintenance. l No timeslot cross device is required on the NodeB side, which reduces the costs and enhances system reliability. l The transmission over the ATM network enhances the usage of the transmission resources and ensures the performance of the CS real time services as well as the sequence of the timeslot data. Disadvantages of CES mode: l CES mode applies to mature 3G networks with enough bandwidth on the Iub interface because it occupies more bandwidth on the interface. l The CES port resource is limited on the RNC side. l The 2G equipment is dependent on the 3G equipment, whose performance affects the stability of the 2G services. l The encapsulation and decapsulation during the circuit emulation introduces delay and delay variation, which affect the QoS of the 2G services.14.6 Topology of the Hub NodeB The NodeB supports the topology with the hub NodeB. The hub NodeB converges the transmission bandwidth of the lower-level NodeBs. The hub NodeB integrates the functions of transmission device. Thus the hub NodeB can converge the transmission data of the lower-level NodeBs. Figure 14-7 shows the network topology of hub NodeBs.14-6 Huawei Technologies Proprietary Issue 04 (2007-06-30)
