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

Example: EDGE and WCDMA carriers in Concurrent Mode

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

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
