Concurrent Mode RF Module Sharing - basic idea

Concurrent Mode = RF Module Sharing, in this presentation Two Radio Access Technologies, RATs share the same RF Power amplifiers The output power of the RF power amplifiers is split between the two RATs All carriers through the shared RF power amplifiers must be in the same frequency band

The benefits of the Concurrent Mode are cost savings Possibly fewer RF Modules Two RATs can share the antenna feeders and Antennas in the same frequency band No need for Antenna line Combiners in simple cases

Concurrent Mode, use cases Frequency Re-farming and BTS Modernizing

Operators plan re-farming GSM frequencies to WCDMA or LTE, to get more data capacity They bring new WCDMA or LTE technology to GSM frequency bands

When they bring new technology, they can easily modernize their existing GSM BTSs They still need to keep some GSM capacity for existing GSM terminal base and for roaming users Operators will have two technologies in the same frequency band Use Concurrent Mode !

Some Operators plan re-farming part of their WCDMA frequencies to LTE At the same time they can easily modernize their WCDMA BTSs Operators will have two technologies in the same frequency band Use Concurrent Mode !

Concurrent Mode, standardization and our message

New ETSI MSR standard will enable Concurrent Mode in Radio Access Network MSR = Multi Standard Radio, allows multiple radio technologies through the same RF Power Amp

Draft MSR standard is estimated to come available in August 2010 Then a vendor can certify their equipment and get the CE mark Radio Network using MSR certified equipment can start operating earliest in September 2010

Vendor B claims they already have a MSR BTS Actually they have separate RF Power Amplifiers for each technology in a single box

It is not certified as MSR BTS. Instead, it is certified as two co-sited single-technology BTSs

NSN has had co-sited BTSs for years

Flexi Multiradio BTS - Concurrent Mode Operation

WCDMA System Module is in the master role in Concurrent Mode It controls shared Antenna line devices (MHA, RET) and shared licenses

The two base stations sharing the RF Module, are both visible separately in NetAct Both base stations have their own alarms and own Performance Management The alarms of the shared RF Module are seen at both technologies in NetAct

NetAct OSS5.3 will support RF Sharing GSM-WCDMA and GSM-LTE

Radio Network planning is still done separately, similar to single technologies

Flexi Multiradio BTS GSM/EDGE Co-Siting Co-Siting technique (3/3)

Sharing of TX and RX antennas using Multi Radio Combiner (MRC)

Sharing of TX and RX antennas using Multi Radio Combiner can be done with Flexi WCDMA release 1 BTS (both BTSs have to operate in the same frequency band).

*) MRC = multi radio combiner

Flexi BTS Redundancy

Automated recovery according to operator preferences

A second Multimode System Module can be installed for providing protection against System Module, transport sub-module and optical link failures

If one of the System Modules becomes faulty, only part of the capacity is lost, because the other System Module can still continue the service

If one of the optical links fails, automatic re-routing of the optical links If one of the RF Modules goes down, only part of the capacity is lost, because the other RF

Modules in the same frequency band can still continue the service

If the main backhaul transport sub-module fails, the 2nd transport sub-module can be used to provide recovery

Flexi Multiradio BTS - Summary Concurrent Mode RF Sharing Site Solution

Frequency re-farming starts in 900 and 1800 MHz bands Operators bring WCDMA or LTE technology to their GSM bands Then they can easily modernize their GSM Network Two radio technologies come to the same band Use Concurrent Mode RF Modules

New ETSI MSR, Multi Standard Radio, standard will enable using Concurrent Mode Radio Network with MSR certified equipment can start operating earliest in September 2010

NSN offers Flexi Multiradio BTS for true MSR Concurrent Mode applications 900 MHz band, GSM-WCDMA or GSM-LTE 1800 MHz band, GSM-LTE 2100 MHz band, WCDMA-LTE
