In the evolution to 4G LTE, optimization in spectrum utilization and multiple technologies radio access networks

covering legacy 2G/3G and new 4G is becoming vital for successful launch of LTE service. Especially, limitation in

LTE spectrum utilization caused by interference issue such as DTT and LTE 800 is threatening the market due to

uncertainty in mitigation solutions. In addition to this, overlaying complexity in RAN / Antenna site derived from

multiple re-farming & legacy networks will be key challenges as this will be resulting in continued pressure on

operator’s CAPEX and OPEX spending as well as time-to-market. Most preferred and cost-effective will be the

solutions adopting very high performance RF filter and combiner technology aimed at steep band-edge skirts

and low signal combining loss. However, traditional RF Filter/Combiner technologies have limitation in realizing

Such high performance.

KMW has been particularly focusing on solving these critical challenges by introducing “Black Hole Filter (BHF)”

using world’s first commercialized “Triple Mode” Filter Technology. KMW offer powerful & cost-effective

approach implemented by “Black Hole Filter (BHF)” to revitalize the three key resources in LTE deployment by

solving the serious challenges come from the resources themselves.

• Spectrum Interference

• Re-farming Multi-RAN Overlay

• Antenna Site Sharing

@710MHz

Even though 800MHz and 2600MHz bands have been newly introduced as the main LTE spectrum, wireless market, especially across EU, express deep concerns about interference issue against adjacent spectrum in use for DTT service and S-band Radar systems. According to UK’s regulatory body, around 750,000 households will be exposed to the interference issue between LTE 800 and DTT service. In LTE 2600 case, approximately 43% of UK’s landmass could be affected by co-channel interference between 2600MHz IMT band and S-band block of 2700~3100MHz. Especially, DTT interference issue is considered as more severe problem, which is requiring very high performance filters as the effective interference mitigation measures.

Among various interference cases affecting DTT service, channel 58, 59 and 60 which are affected from LTE 800 Block A transmit where in or close to a center of population is very critical. One of the way in mitigating interference from block A to channel 58 and above is reductions in Base Station Power. However, any reduction in the allowed 800MHz EIRP will lead to a reduced 800MHz coverage when compared to a 900MHz network deployed on a similar grid. In order to compensate for this, the 800MHz network operator would need to deploy further 800MHz bases stations resulting in more 800MHz base stations closer to populated areas (further increasing the risk of interference between LTE800 and DTT services) and additional cost to the 800MHz deployment. By this reason, high-performance filter at LTE800 BTS is the effective measure in order to enhance the frequency selectivity of DTT receiving system by protecting the carrier power received from LTE 800 BTS.

KMW’s advanced “Black Hole Filter” Solution enabling sharp roll-off performance can be a cost-effective & simple solution to address this particular DTT interference issue in LTE 800 deployment. As more new spectrum and re-banding will be introduced in the market, a lot of problems related to interference or system emission will be more seriously uprising. Thus, KMW’s sharp roll-off filter solution aimed at “Recapture Lost Spectrum” can be adopted to most of congestions in every spectrum bands over the world, such as ;

• Between LTE 2600 band and Radar Systems starting from 2.7GHz • Between air-to-ground service and wireless networks • Between public safety band and wireless networks

Why KMW’s Interference Mitigation Filter

This high-performance filter requires a sharp stop-band attenuation with 1MHz guard band between DTT channel 60 (782~790MHz) and LTE 800 transmit Block A (791~801MHz) as shown the frequency response of the Filter in Figure 2.

Spectrum reuse by re-farming is widely spreading over the world to cope with exponential mobile data growth in scarce spectrum environment. The most dominant market trend is re-use of existing GSM 900 and GSM 1800 band for UMTS or LTE service. Regardless of spectrum and technology adopted to the planned re-farming, the following key goals express operator’s biggest concerns in planning of the re-farming network deployment.

- Maximize spectrum utilization while minimize investment in new LTE networks - Efficient cell plan & optimization by balancing grid between legacy and new LTE networks - Minimize spending in construction of new site infra by re-use of the existing site and infra - Time-to-Market through time-effective planning & deployment

Revitalize Re-farming Multiple RAN - Co-site In-band Combiner

All infrastructures which are built in each cell site, such as RAN, tower, mast, antenna, feeder represents history of operator’s strategy linked to future network evolution. Many operators want to deploy new LTE network by overlaying onto the legacy network grid in order to secure ROI in the existing network infra. In this case, many operators desire to reuse their existing GSM sites, antenna and feeders to deploy planned LTE (or UMTS) network through simplified spectrum migration scenario. In this overlaying scenario, RF in-band combining (so-called Same Band Combining) solution can be the effective way, maintaining both streamlined network history and future network evolution by reuse of the existing infrastructure for legacy networks.

Conventional filter combiner solutions often require wide guard bands to be placed between GSM and new LTE in the co-location applications, thus lowering the capacity and wasting valuable spectrum. Also, these conventional filter technologies cause high signal loss in narrow guard band condition, which impact to significantly reduced coverage and throughput. This technical limitation sometimes causes operator’s over-spending or impact to time-to-market driven by ineludible decision of total swap of existing legacy RAN to new multi-standard /technology RAN or new site acquisition & construction. To overcome these challenges in a re-farming service targeting overlay of new LTE RAN onto legacy RAN, highly integrated & advanced combiner solution should fulfill the following key Requirements.

• Support 2x2 MIMO per each GSM and LTE System • Minimized Guard Band for Signal Combining (< 1MHz) • Low Signal Loss (< 1dB typical per each Up & Downlink) Figure 4. KMW’s In-Band Combiner Performance

Revitalize Antenna Site – Antenna Sharing between Operators

Typical CAPEX analysis model shows that a majority of costs are related to establishing coverage as like radio access related CAPEX. Around 70% of the CAPEX involves acquiring the sites, access equipment, civil works like construction of the site, installation of the equipment. Thus, passive infrastructure sharing including site and tower by cooperating with operators has been accelerated to minimize such costs. However, with the 4G LTE era, these fundamental implementation issues will be much more complicated by the lack of sites, limited tower capacity, tighter environmental regulations, and health concerns regarding the hazards of radiation. Especially, 4G LTE mixed with legacy multiple networks and multiple technologies requires new additional antenna systems or swap to heavy & sizable multi-band antennas. By this reason, acquisition of sites and build of new tower/pole are more difficult and impact financial strength as well as time-to-market. In order to reduce these risks, active network sharing including sharing of RAN and RNC is also one of the ways. However, it requires very high-level of trust between competitor operators and tight regulatory approval related to competition law. By this reason, many operators are proactively encouraging rather simplified wireless infrastructure sharing for their financial strength and this traditional infra sharing scheme has been focused on passive infra only such as shared sites, masts, electricity, fan and so forth. In the complicated 4G network with multiple networks & technologies absorbing 2G/3G, one of the key access network element causing critical problems is base station antenna. Thus, antenna sharing between multiple operators will be one of strategy to overcome severe market situation and CAPEX & OPEX pressure for new site & mast as well as opposition from building owner, residents and regulators. Moreover, new market entrants which have difficulty in coverage expansion or new site acquisition can utilize this antenna sharing strategy as one of economical drivers. Through this antenna sharing approach, around 5~10% of additional spending can be saved from market analysis and there are further noticeable merits beyond cost saving.

Conventional Site & Mast Sharing (10~20% Total Cost Saving)

+ Save Cost 10% more by Antenna Sharing Solution !! And, Physically Simplified Tower & Rooftop Limit Costs of New Site & Tower Construction Reduce Energy Use & Environmental Impacts Fast Planning, Site Acquisition and Roll-out Foster Low Cost & Unified Expansion into new areas Reduce Opposition from Building Owner, Residents & Regulators

Effective combiner solution is required to realize antenna sharing between multiple operators to secure scarce & valuable spectrum and coverage as it is with minimized impact, especially in case the incumbent operators placed between adjacent spectrum. One of the perfect application for the site & antenna sharing combiner is the interference issue between LTE 800 and DTT service because it reduce around 10% of households whose DTT service might be affected according to market analysis. Therefore, site & antenna sharing has much significant benefits such as reducing mobile network CAPEX/ OPEX, as well as simplifying the task of mitigation coordination among the licensees for LTE 800 through co-work in cell & coverage planning and real deployment. In typical deployment stage based on site/antenna sharing Agreement between LTE 800 licensees, responsibility for three key factors such as shared antenna combiner and guard band allocation should be collaboratively defined for effective & simplified task process as shown in the example

KMW’s antenna sharing combiner solutions supporting 2X2 MIMO are designed to address this market need through advanced filter/combiner technology enabling narrow guard band (<1MHz between operators) and minimized signal loss (Typical < 1dB) for secure of valuable spectrum and network coverage with minimized sacrifice. KMW‘s commercially proven core solutions deepen market adaptability of the site/antenna sharing between multiple operators and this solution can be implemented into all the spectrum bands & technologies such as 800 / 900 / 1800 / 1900 / 2100 / AWS / 2600MHz used in GSM/CDMA/UMTS/ LTE networks. Especially, antenna sharing between multiple LTE 800 operators provides significant benefits in saving of network spending as well as efficient joint-measures to minimize interference issue between LTE 800 and DTT service

In the evolution of wireless communication, introduction of new spectrum for 4G LTE and multiple RAN network & multiple technologies covering refarming 2G/3G and new 4G is creating considerable limitations in spectrum efficiency, RAN and antenna site. This is causing in continued downward pressure on network operator’s CAPEX and OPEX spending as well as time-to-market, which will be weakening competitiveness in the wireless service. These limitations around the wireless market should be resolved through cost-effective solutions without sacrifice in the valuable spectrum and network performance. Especially, spectrum band is the most important asset which costs sky-high and the major concern is “How to maximize utilization of valuable spectrum with less signal loss”. For this, filter technology for wireless communication systems is ever evolving to, among other things, maximize frequency spectrum utilization and provide optimum solutions to manage limited bandwidth. Today’s conventional Cavity filters and Dielectric Resonator (DR) filters are widely used in overall communication systems. But, the need for more efficient filters is even greater with the advent of new 4G networks overlaying the existing 2/3G infrastructure, particularly in areas of limited spectrum and base station resources. Requirements for high attenuation with low insertion loss and small size are key issues in filter technology for communication systems. KMW has already begun a new era in RF filter technology by introducing the “Black Hole Filter (BHF),” using the world’s first commercialized “Triple Mode” technology which is capable of providing high stop band attenuation with low insertion loss in a relatively small package.

What is “Black Hole Filter” ?

The KMW’s innovative approach to “Triple-Mode” technology enables three distinctive resonances with only one resonant cavity, utilizing a dielectric resonator with high Q value inside the single pocket. Compared to conventional Dielectric Resonator filters, the triple mode “Black Hole Filter” offers very low insertion loss, extremely high attenuation, with a significant size reduction. Inside the pocket, waves can travel without bending and distortion, achieving the highest possible Q and steepest band-edge skirts ever in a single pocket filter.

The conventional single mode filter provides only a single resonance mode in the single pocket. The triple mode filter generates three distinctive resonances using the TE01δ mode as same as the single mode filter. But it also enables two additional TE01δ modes allowing the single cavity to function as three cavities which improve the performance and lower manufacturing cost. The single mode filter with 8 resonators can be replaced by the triple mode filter comprised of only two resonators while achieving the same performance, occupying less than a third of the size of the conventional DR filter. With the deployment of micro base stations including Remote Radio Head (RRH) systems, and the overlay of multiple frequency bands for multiple standards on a single cellular site, the space available for the RF hardware is decreasing. Since RF filters typically occupy a significant fraction of the base station volume, base station manufacturers are looking for filter technologies that offer size and cost reduction, while still meeting the stringent base station RF specifications of insertion loss, rejection and power handling.

KMW has been bringing industry leading filter technology and RF products to the market since 1991. Future of wireless market environment will be much more challenging due to serious congestions driven by introduction of new spectrum bands and multiple network technologies. KMW is deepening new paradigm of filter technology with “Black Hole Filter” by the “Triple Mode” resonance and its mission is offering breakthrough solutions to take advantage of all the benefits that evolutionary wireless communications will give around the world.
