LTE Bands vs Channel Bandwith

Source: 3GPP TS 36.101 version 10.7.0 Release 10

More spectrum i.e. more capacity available at higher frequencies

LTE and Carrier Aggregation

• LTE Rel 8 & 9

– Single-carrier operation

– Bandwith from 1.4 MHz, through 3, 5, 10, and 15, up to 20 MHz

• LTE Rel 10

– Aggregation of up to 5 “component carriers” i.e. the LTE Rel 8 & 9 carriers

– As a result up to 100 MHz (i.e. 5 X 20 Mhz)

– Each component fully compatible with Rel 8 & 9 i.e. co- existence of Rel 8, 9, & 10 Ues possible

Site coverage is inversely related to the frequency band (i.e. the higher frequency band, the smaller the coverage).

LTE Prime Spectrum Bands • New Spectrum

– 2.6 GHz in Europe & APAC (main LTE capacity band) auctions completed in many european countries

– Digital Dividend (coverage bands)

• Most Common LTE Bands (FDD) – 700 MHz: band 12, 13, 14 & 17 (new) – 800 MHz: band 20 (new) – 1800 MHz: band 3 (typically re-farmed) – 2600 MHz: band 7 (new)

• Other LTE Bands – 2.1 GHz : band 1 – AWS: band 4 – 900 MHz: band 8 – 850 MHz (Japan - various): band 6 – 1700 MHz: band 9

NA - 700 MHz - AWS

LATA - 700 MHz - AWS - 2600 MHz APAC

- 700 MHz - 800 MHz - 1800 MHz - 2100 MHz - 2600 MHz

Middle-east - 900 MHz - 1800 MHz - 2300 MHz - 2600 MHz

Europe - 800 MHz - 1800 MHz - 2300 MHz - 2600 MHz

Digital Dividend Bands • Switchover from analog to digital TV • 2007 World Radio Conference (1st

Digital Dividend) – Region 1 (Europe, Middle East and Africa) identified

790–862 MHz for mobile services : Band 20 – Region 2 (Americas) identified 698–806 MHz : Band

13-17 – Region 3 (Asia) mobile allocations are 470–960 MHz,

with a number of Asian nations identifying 698–806 MHz for IMT systems.

• 2012 World Radio Conference (2nd

Digital Dividend) – allocate more UHF spectrum for mobile services in

Region 1 (Europe, Russia, Africa, parts of Middle East). This allocation, 694–790 MHz, to come into force in 2015, is next to the existing digital dividend band (790-862 MHz).

band plan for Region 1 with the lower portion of the Region 3 700 MHz band

LTE Re-farming Bands LTE Refarming in NA - 1900 MHz - AWS - 2600 MHz (TDD)

APAC - 700 MHz - 800 MHz - 1800 MHz - 2100 MHz - 2600 MHz

LTE Refarming in Middle-east

-1800 MHz - 2100 MHz (TDD) - 2300 MHz (TDD) - 2600 MHz (TDD)

LTE Refarming in Europe

- 900 MHz - 1800 MHz - 3500 MHz (TDD)

LTE Refarming in LATA

- 1900 MHz - AWS - 2600 MHz (TDD)

Q4-2011: 30% LTE Subscribers served by re-farming bands (mostly AWS & 1800 MHz)

Evolution of frequency band allocation New Bands:

- 2.6GHz spectrum mainly for LTE; mainly for hotspot and dens urban areas

- “Digital Dividend” (e.g. 800MHz/700MHz bands): mainly for suburban and rural areas

2.1GHz Band: Mainly for UMTS/HSPA/HSPA+

900MHz & 1800MHz Bands;

to LTE

- 900MHz refarming already started for UMTS usage

- 1800MHz will be re-farmed directly

Re-farming 2G Band into LTE Band

• The Whole BW is 2G i.e. mostly voice traffic

• Re-farming some BW from 2G to LTE i.e. increased data traffic

• The whole band is LTE i.e. with LTE offering both voice & data support

Commercial RAN vendors offer flexible spectrum

sharing among multiple RATs (e.g. 2G & LTE)

LTE in re-farming spectrum : The 1800 MHz Case • Widespread Allocation

– More than 350 operators are estimated to have been allocated 1800 MHz spectrum

– Today 1800 MHz is mainly used for voice (GSM) service – GSM voice traffic is peaking/reducing; data traffic is growing exponentially – 1800 MHz is a prime band for LTE international roaming

• Large Spectrum – In many markets 1800 MHz represents the largest spectrum allocation – 60% of 1800 MHz spectrum in the top 7 EU markets (*) is available in 10

MHz or wider assignments – 1800 MHz band is harmonized, non-fragmented, and often only partially-

utilized

• Technical Advantages – Coverage area is about 2X larger than LTE2.6GHz with better indoor

penetration. – 35% improvement in cell edge throughput compared to LTE2.6GHz. – Reduction of Extra sites results in quick delivery of the LTE to market.

Providing initial widespread coverage with LTE in the 1800 MHz band can be as much as 60% cheaper than covering the same area with LTE using higher frequency bands

– Reuse of existing GSM1800 sites and possibly share antenna systems

• Ecosystem Readiness – 1800 MHz RF components now available in volume production from

multiple vendors – 14 commercial LTE1800 networks launched

* France, Germany, Italy, Norway, Spain, Sweden, UK

LTE1800 Market Status (Q2-2012)

• 20+ Commercial LTE1800 Networks in 15+ countries

• Band 3: 2 X 75 MHx (Total Spectrum)

• 100 LTE1800 Devices Available
