NOTABLE NOTES
Project Velocity IP ‘VIP’ = 40,000 small cell deployments
1,000 DAS deployments By the end of 2014
First to install a na:onwide
commercial residen,al femtocell service
Juniper Networks research reveals U.S. number 4 in LTE penetra,on (a\er S. Korea, Japan and Australia)
DAS vs. Small Cell
DAS Small Cell Can cover mul,ple operators, frequency bands and technologies (GSM, CDMA, HSPA, LTE & WiFi)
Developed as an eye for leasing (homes, enterprises, metro cells, rural and mul,-‐technology)
Deployed by operators, neutral host or landlords
Typically serves just one operator & one technology
Effec,ve for complex, large deployments
Good for piecemeal deployments in smaller spaces
Coverage solu,on and supports increased capacity needs
Support for hot spots to gain beder coverage & capacity
Deployed outdoors & indoors Deployed outdoors & indoors
VS.
Some similari,es, different technologies, different needs. Both are stronger together as a combined/integrated solu:on.
Key Challenges
VS Challenges for both DAS and small cell deployments are similar:
Power / Real Estate / Backhaul
-‐ Finding an outdoor site for small cell deployments can be expensive -‐ Lack of access to power -‐ Backhaul solu,ons are expensive and inefficient -‐ Management of a ‘converged’ network of macro cells and small cells is
cumbersome -‐ Today’s integrated networks are complex to install -‐ Outdoor deployments complex (can’t just hang a system on a u,lity pole) -‐ Biggest building boom for telecom in years – lack of access to
knowledgeable, experienced employees and experts
Everything in wireless takes longer!
Considera,ons: Discerning the Right Solu,on
VS -‐ Macro cell network alterna:ve solu:ons/considera:ons
-‐ Adding spectrum or carriers -‐ Upgrading to a higher modula,on scheme -‐ Employ sectoriza,on
-‐ Small Cells -‐ Experience -‐ Less solu,ons deployed means less experience in the
market -‐ Volume – How many devices are being deployed in the field and how
will it effect the network -‐ Control of the network – retaining control of the network is a key
considera,on to ensuring customer care -‐ DAS
-‐ What is it good for? An unclear customer base such as those in entertainment venues, hospitals, arenas, higher educa,on campuses, etc.
It’s not a DAS vs. Small Cell World
VS Not always either/or it could be both/and….
‘THE ERA OF CONVERGENCE’
-‐ Small cells are just one part of the larger array of op,ons -‐ Macro cell sharing solu,ons could spawn interest in small cell sharing
models -‐ Wireless Technology is as essen,al as plumbing, hea,ng and ligh,ng -‐ DAS is considered the 4th u,lity -‐ Converged architecture brings licenses and unlicensed networks together
enabling great coverage and capacity -‐ “I could be used to complement. I don’t see small cells replacing DAS”
according to Aditya Kaul, Analyst at ABI Research Macro cell, small cell and DAS all work together to provide
beaer capacity and coverage.
The Future is Bright
VS
-‐ Small cell deployments will grow faster (because not as many have been deployed so far)
-‐ Small cell with distributed macro cell solu,ons are changing the way new LTE RAN will be designed
-‐ Small cells are just one part of the larger array of op,ons
New Technologies and new business models are constantly changing! -‐ Mul,-‐Standard Metrocells (MSMs) – AT&T’s solu,on deploys small cells
in a single unit that combines LTE, HSPA and WiFi -‐ Innova,ve Technologies like Small Cell RAN (Ubiquisys/Cisco) -‐ Alcatel-‐Lucent’s Lightradio Live -‐ Self-‐Organizing Network (SON) technology -‐ Femtocell as a solu,on (FaaS). ABI Research predicts that 10% of
regional carriers in the US will us FaaS providers for: -‐ Wholesale delivery of femtocell services
AND MUCH MORE!

The Problem -‐ Wireless vs. Wireline
• 51.7 percent of U.S. homes don’t have or didn’t use their landlines in the first half of 2012. And this is expected to con,nue to increase.
The Problem – Mobile Data Usage
• According to Heavy Reading (trade publica,on) 50% of all mobile data usage is at home in 2011; by 2016 projected to be 65%.
• According to Pew Research, 66% of 18-‐29 year olds have Smartphones, 45% of total adults have Smartphones.
• Smartphone and Tablet users require between 50 to 120 ,mes capacity of standard cellphones.
• According to Ericsson and GigaOm, data now accounts for 85% of all cellular traffic.
Summary: Mobile data usage will grow dramaHcally and indoor-‐at home wireless service is, or will become very important.
The Problem – Green Buildings
• Energy efficient windows (“Low E Glass”) effec,vely block a significant amount of wireless (RF) signals from entering/leaving buildings resul,ng in poor coverage.
The Solu,on -‐ DAS
• Advantages of DAS for Residen,al Hi-‐Rise Applica,ons – Single antenna system supports mul,ple carriers and technologies (minimal visual impact)
– Install once, future changes all in Head End (invisible to residents)
– Poten,al synergy with current/future Public Safety requirements
– Centralize ac,ve elements (no need to access residents private space aPer iniHal installaHon)
The Solu,on -‐ DAS
• Challenges of DAS for Residen,al Hi-‐Rise Applica,ons – Keeping antennas “hidden” – Cost, including DAS and BTS/Repeater equipment
• ROI model for WSP is weak • Strategic value?
– Space alloca,on (IDF closets and Head End Room) – and associated “cost”
The Solu,on – Small Cells
• Advantages of Small Cells for Residen,al Hi-‐Rise Applica,ons – Low cost per unit (Few thousand $$) – Ease of installa,on – No need for a Head End Room (saving on real estate)
The Solu,on – Small Cells
• Challenges of Small Cells for Residen,al Hi-‐Rise Applica,ons – Keeping the quan,ty required to a minimum
• One Small Cell = one WSP • One Small Cell = one technology (currently) • Limited power = limited coverage area • Limited capacity
– Backhaul – requires Ethernet connec,vity from each Small Cell back to the WSP switching network
– Maintenance, especially if Small Cells are installed in apartments
The Solu,on -‐ WiFi
• Advantages of WiFi for Residen,al Hi-‐Rise Applica,ons – Low Cost (especially for private wireless routers) – High speed and large capacity available (100 Mbps per user), with higher speeds imminent (802.11ac)
– One technology -‐ Supports all Smartphones, tablets, Roku, xBox, AppleTV, etc.
The Solu,on – Small Cells
• Challenges of WiFi for Residen,al Hi-‐Rise Applica,ons – Interference/Reliability – Lack of connec,vity to WSPs
• May change soon – Hotspot 2.0
Conclusions
• DAS vs Small Cells* – DAS for larger buildings (500,000 sq \ or larger) – Small cells for smaller buildings (100,000 sq \ or less) – Case-‐by-‐case determina,on for 100,000-‐500,000 sq \ buildings
• Deploy managed WiFi in common and amenity spaces

E-‐MBMs
• Evolved Mul,media Broadcast Mul,cast Services (MBMS) is a point-‐to-‐mul,point interface for exis,ng and upcoming 3GPP cellular networks, which is designed to provide efficient delivery of broadcast and mul,cast services, both within a cell as well as within the core network.
• The service is aimed at reducing network load when there's some traffic workload that everyone on the network in either a single cell, region, or en,re network are likely to watch or view
Smart use to the spectrum
Applica,ons
Broadcast transmission across mul,ple cells, it defines transmission via single-‐frequency network configura,ons. Applica,ons include:
– Mobile TV and radio broadcas,ng – File delivery – Emergency alerts
Applica,ons
• Venue-‐specific broadcast – Sports / arena only – Rich media: mul,ple cameras, replays, sta,s,cs
• Region-‐specific broadcast – Home team games – Local events/news
• Na,on-‐wide broadcast – World Cup and Super Bowl – Breaking news – Emergency alerts
When?
• Verizon announces 2014 to offer eMBMs service on its LTE network

VoLTE
• VoLTE: The promise of LTE – One flat IP network for both voice and data
• VoLTE first deployment: MetroPCS (2012), Verizon (2014) – VoLTE/IMS for call control
• VoLTE requirements – 2G-‐3G voice quality (beder than VOIP which is best effort) – Low latency – RAN Op,miza,on goal (SINR 10 dB over 90% of coverage area)
Customers will evaluate the network based on the QoE of the voice network

VoLTE Enablers
Why VoLTE is not just another VOIP Service • QoS
– Dedicated data bearer – Dynamic scheduler at base sta,on – Quality of Class Indicator (QCI) for sesng priority
• RAN Enhancements – Semi-‐persistent scheduler – Transmission Timing Interval (TTI) – Robust Header Compression (RoHC)
• IP Mul,media Subsystem (IMS) – Session Ini,a,on Protocol (SIP) – Policy and Changing Rules Func,on (PCRF) – Real ,me transport protocol (RTP) – Real-‐,me Streaming Protocol (RTSP)
New Spectrum Opportuni,es
• US Spectrum Opportuni,es – 600 MHz Band via FCC incen,ve auc,on (2014)
• Up to 126 MHz of spectrum from UHF analog TV
– 1695 to 1710 MHz (15 MHz) 2015 FCC target – 3500 Band up to 100 MHz of spectrum for small cells (2015 FCC target)
• Shared with military and marine radar systems in coastal regions
• EMEA Spectrum Opportuni,es – 700/800 Digital Dividend (E-‐UTRA Bands 20, 28 and 44)
• Available due the transi,on from analog TV to Digital • Under review at the Wireless Radio Communica,on Conf. (2015)
– 1700 and 2100 band (25 MHz each)
Spectrum Proper,es
• Not all spectrum bands are created equal – Lower frequency bands (450 -‐ 900 MHz)
• Travels long distance for coverage • Good building and foliage penetra,on
– Higher frequencies (1700 – 2600 MHz) • Poor distance coverage • Poor building and foliage penetra,on
– 2600 MHz typically requires 9x number of antennas to provide the same coverage as 700 MHz
• Rural areas (key factor is coverage) – Lower frequency band beder
• Urban areas (key factor is capacity) – Will require large number of cells anyway to provide coverage – LTE uses 1:1 frequency reuse, more interference issues with lower frequencies
• In-‐building (key factor maybe capacity (stadium) or coverage (conven,on center))
vs
2600 MHz 700 MHz
Spectrum Usage in LTE-‐Advanced
• LTE-‐Advanced (Hetnets) – Geo-‐locate hotspots in a sector and add a small cell to improve capacity – If using same band, requires inter-‐cell interference coordina,on (complex) – Prefer to use high frequency band (3500 MHz) for Small Cell
• No interference issues or coordina,on required and doesn’t travel far
Macro Cell
Small Cell Low throughput around edges without interference coordina,on
– In-‐Building (Stadium Example)
Poor separa,on between yellow and red sectors
Employing separate bands (AWS and 3500) reduces noise (higher SINR) thereby maximizes throughput (capacity)
AWS 3500
How do we Maximum Capacity?

More Spectrum • Limited licensed spectrum available • Expensive
Migra,on to LTE LTE MIMO
Increased Cell Density
Spectrum Efficiency
• Largest and fastest return on investment • Beder spectral efficiency, throughput improvement Op,miza,on
Must employ all of these solu:ons to solve the spectrum crunch
• Carrier grade WiFi and backhaul required • 33% of mobile traffic in 2012 (Cisco VNI Mobile 2013)
WiFi/Femto Cell Offload
• Small Cells and DAS (expensive) • Backhaul required to each cell/DAS
• Migra,on to LTE and LTE Advanced • LTE MIMO
Spectrum in a 5G/6G World
• 5G/6G Requirements (2020 and beyond) – 10 – 100x data rates (10 Gb/s download speeds) – 1000x capacity/area – 100 Gb cell capacity
• Spectrum Opportuni,es (to achieve high data rates) – Microwave (3 GHz – 30 GHz) and Millimeter Band (30 GHz – 300 GHz)
• 24 GHz – 40 GHz currently being inves,gated • Line-‐of-‐sight and short distances (1m -‐ 60m realis,cally) • Severely affected by rain, fog, snow, foliage, etc.
– Lots of spectrum is available
• WiFi Offload – 802.11ad (WiGig)
• 60 GHz spectrum with a range of <10m (7 Gbps download, up to 25 Gbps)
Next Genera:on mobile technology will be primarily for in-‐building use
Summary and Conclusions
• Spectrum is a finite and expensive resource – The Radio Access Network (RAN) is the most cri,cal piece of the mobile
network • Air environment is an uncontrolled medium unlike fiber or copper • Subject to environmental condi,ons • Anyone can generate a source of interference • 1°variance in antenna azimuth or ,lt can result in 10 dB signal difference (dropped calls or
Mb/s reduc,on in data throughput)
• Op,miza,on of in-‐building RAN must be done during deployment – Unable to get access to the building later for op,miza,on
• Next Genera,on Mobile Technology will be in-‐building centric
Mobile networks will become so cri:cal that future RANs will have live network monitoring of the over-‐the-‐air signal
