IWPC - Flexible 4G Base Station Architectures Workshop

NEW – International Wireless Industry Consortium
Interactive Technical Workshop

Workshop Background: In 2G and 3G networks, deployment took place using base station hardware that was highly optimized for the immediate task of providing coverage and capacity for known operating modes and frequency bands. Especially in 2G infrastructure, the frequency bands and air interface standards expected from the hardware were very well understood and were not anticipated to change dramatically over time. MIMO was not a dimension to consider, beyond diversity at the base station RF level. We've learned some important lessons in the ongoing upgrades to 2G and 3G systems. Many network operators now wish that they had invested in more flexible hardware from the beginning to avoid "fork lift upgrades" for 3G overlays in 2G spectrum, or to avoid hardware upgrades for new waveforms such as HSPA. With the deployment of OFDM systems the world has changed. Nowadays it's not straightforward to plan which spectrum allocations will be used for OFDM services vs. other mobile/wireless services. We can be certain that there will be a huge variety of combinations in OFDM signals mixed with 2G and 3G signals, different MIMO configurations, and upgrades to the air interface standards....all of this complexity will require flexibility to be inherent in 4G hardware. We will need flexibility to higher order MIMO modes, a wide variety of frequency bands and bandwidths, and the ability to increase peak-to-average ratio (PAR) in the air interface.
Workshop Goals: The primary goal of this workshop is to determine the optimal level of flexibility in WiMAX and LTE base stations. Should we design in options for upgrades from 2x2 MIMO to 4x4 or higher modes? Should we use a modular approach to allow for quick, easy upgrades to hardware? Should base stations be designed to be reconfigurable for multiple mobile spectrum possibility? Should OFDM base stations handle 2G and 3G signals also? Will all this flexibility be expensive, and is it worth the added cost? How can networks become self-configuring and self-optimizing to make upgrades more seamless? We will examine these design options with a view to minimal cost for operators, over the total life cycle of the network. In other words...is it possible to spend a little more on initial CAPEX to save on upgrade CAPEX and ongoing OPEX? Is this a desirable tradeoff for operators?
