Workshop Background

The number of options, both in a given region as well as worldwide for delivery of wireless mobile services has been increasing over the last several years.  In addition, there is pressure to move from 2G to 3G to 4G and beyond.  This can render existing infrastructure obsolete and result in costly upgrades or wholesale equipment replacement.  

In addition, frequency allocations and spectral requirements worldwide are not totally harmonized requiring costly customized designs of equipment for regional needs.  

One approach is to establish flexible basestation designs capable of being adapted to the local requirements with a minimum of equipment change.  This flexibility can range from simple plug-in/plug-out of key pieces or, in its most ambitious form, dynamic adaptation to the changing requirements.

Significant advances have been made in developing software and baseband systems capable of addressing several of the access format requirements.  However, the realization of RF systems and subsystems with sufficient flexibility to respond to these different requirements remains a very difficult challenge.



Workshop Goal

The goal of this workshop is to: 

  • examine and identify the requirements for the kinds of flexibilities in basestations which are of value or attractive,

  • determine the demands these place on the RF systems and subsystems, and 

  • explore the technologies and solutions which different organizations in the supply chain can identify and propose to respond to these demands.

SIEMENS and alcatel Keynotes


Overview of Cellular Networks and network architecture options for possible application of Basestation Reconfigurability

How might the reconfigurability affect use of more distributed networks or repeaters?

Which parts of the network would be required to be updated or replaced?  What might be conversion plan look like and over how much time?

What are the key factors and implications which OEMs wish to ensure the Operators are aware and informed of and sensitive to?

  • Network operations

  • Network overlay vs. new sites

  • Implication on handset capabilities

  • Installation, Maintenance, Repair, Servicing

  • Energy Consumption

What are the questions they would like to operators to respond to to better appreciate their concerns?

What are the key challenges to the RF Subsystem suppliers to meet the demands of reconfigurability of basestations?

What are the various levels of reconfigurability now and in future?

What kinds of scenarios might be foreseeable for functional requirements on the basestations?  e.g. GSM conversion to UMTS; Cell phone handoff to local WiFi network; Service switchover to WiMAX?

What are the implications of the OBSAI and CPRI interfaces on reconfigurability?

  • What might they see as the benefits or drawbacks from use of reconfigurability in basestation networks? 

  • What do the operators see as the key parameters and economic drivers to assess in evaluating reconfigurability and its impact on their operations? Maintenance; energy consumption; installation costs; flexibility; future proofing;  etc.

  • How do the service providers and consolidators foresee introduction and use of reconfigurability into their networks?

  • What do the operators see as a challenge to operate a multi-standard network (neighbour lists, handover parameters, etc.)?

  • What are the tradeoffs between OPEX and CAPEX implications in moving to these kinds of systems?

  • What might they see as the implications on reconfigurability of moving to more distributed basestation network architectures? 

  • Would they be deployed as overlay networks or enhancements to existing basestations?

ANTENNA and Low Noise, Broadband 

Receiver and filter SUBSYSTEM SUPPLIERS


What are some Broadband or Tunable Antenna Concepts for covering all or several of the cellular operations frequency bands?

What electronics should be combined with the antenna?

What are the major technology hurdles to implementing the radio electronics to be mounted near the antennas rather than in sheltered hotels?

Can low noise amplifiers which are designed to be combined with the antennas achieve the broad bandwidths required?

What is the impact of the establishment of the CPRI and OBSAI interfaces?

Should the power amplifiers be mounted at the masthead or not?  What are the hurdles?

How can antenna suppliers support Smart antennas and MIMO?

What are the challenges and expected performances of wideband low noise amplifiers?

What innovations are taking place for low noise broadband receivers?

What are the filtering challenges and solutions for low noise receivers?

  • What do power amplifier designers see as the requirements and key challenges?

  • What would the PA Suppliers wish for the system OEMs to address, consider and provide to help them better respond to their requirements?

  • What might they see as the relative economic implications of designing and providing for the specific RF performance requirements of reconfigurable basestations? 

  • What do power amplifier designers see being able to achieve in:

    • Power ranges

    • Bandwidths

    • Efficiency

    • Linearity

    • Reliability

    now and over the next few years?

  • How do they see the tradeoffs between these?

  • What do they see as the key challenges which the device and materials suppliers should address to help PA Designers meet these above requirements?

  • What are current issues in Power Amplifier linearization concepts?

    • How might these approaches be affected by or respond to the desire for  wide bandwidths, high linearity and high efficiency?

    • What are the relative merits of the different linearization techniques  with the latest power semiconductor candidates in LDMOS, GaN and GaAs?

    • How do the different linearization techniques work with the newly emerging power device operational schemes moving from Class A, AB etc to advanced switched mode classes?

  • How do the OBSAI and CPRI interface standards affect, if at all, the way PAs for are built for reconfigurable basestations?

  • What do superconductivity base approaches offer for the future of reconfigurability?

    • Filtering

    • Frontends

    • Demodulation

    • Transceivers
