The In-Building Wireless World

Where are the Users?Wireless personal communications is nowadays one of the fastest industries in the world, with

millions of new customers signing in for new services and applications. In particular, most of

these users are inside buildings, with the exception of those who are on the move: in their

offices, at home, at ports of entry (airports, railway stations, etc.), at shopping centres,

university campuses, etc. Rarely, the majority of the users are outdoors, except when they

are going from one place to another, travelling or commuting. Also, the effect that many

users are concentrated into small areas is also commonly seen.Due to the evident importance of in-building systems which serve users inside buildings,

many questions arise from these observations. How much effort shall we devote to

guarantee sufficient coverage levels inside buildings? Is the signal from external cells enough

to penetrate inside the buildings? How do the radio waves travel and behave in such

environments? These and other questions are the subject of our study as part of this

certification program.

Motivation for Small Cells

To provide wireless coverage inside buildings, smaller cells have been proposed, if sufficient

coverage is not achieved from external cells. Amongst the motivations for using small cells

are the following:

Hot desking

Seamless outdoor-indoor transitions, since users should not be aware of when they

are handing over to a different type of cell when they enter or leave a building

Need for uniform user environment with a single terminal, in line with the overall

system integration seen worldwide in the last years

Higher data rates which can support interactive and streaming applications

Small invisible antennas, better suited for portable devices

Maximum electromagnetic (EM) exposure issues, to comply with Health & Safety

recommendations

Private systems and special billing

Wireless Local Area Networks (WLAN) and Personal Area Networks (PAN)

Building space efficiency and reconfiguration costs

Better interference management Location-based services

In-Building Wireless Applications

Applications and Services

Various wireless applications are well known and have been around in the market for many

years, providing voice and data services to users at different data rates. From 2G systems

where voice traffic was predominant over other applications and limited data transfers were

available, to the more demanding mobile broadband applications which demand large

bandwidth usage and faster data transfers. Hot desking, video streaming, file sharing, web

browsing, mobile TV, interactive gaming and mobile e-commerce are becoming nowadays a

reality in modern wireless systems.

Wireless Technologies Evolution

Since the first cellular technology deployed in the 80s, new wireless technologies were

developed by different standardisation organisations and were implemented by operators.

For cellular technologies, First Generation phones (AMPS) were launched in 1983, supporting

only basic mobile voice, and were the only technology until the late 80s early 90s, with theadvent of Second Generation (2G) phones, in the quest for capacity and coverage. Many

standards such as IS-136 (TDMA), GSM and IS-95 (CDMA) appeared around 1993. In 1995

the quest for data and higher speeds drove the creation of Third Generation (3G) systems,

which for many years provided evolution technologies such as GPRS and EDGE until full

capability could be achieved around 2001. Other standards such as UMTS, IMT-2000

emerged. Beyond 3G in quest for broadband wireless multimedia services is emerging now,

seeing technologies such as OFDM and MIMO, and standards such as HSDPA, 3GPP2, etc.

For WLANs, Wi-Fi became very popular since 2001, and around 2005 wireless mesh

networks were deployed. WiMAX has emerged as a broadband wireless technology around

2007. The tendency is to see low-power networks as well as embedded ones in the near

future.

First Generation (1G)

The First Generation (1G) cellular technology regroups analogue technologies which supportvoice traffic only. In America, AMPS (Advanced Mobile Phone System) was launched in

1983, having a channel bandwidth of 30 MHz only, sufficient for voice, and using Frequency

Division Multiple Access (FDMA) as the multiple access technology.

Second Generation (2G)

The Second Generation (2G) includes digital technologies that provide an increased voice

quality over the first generation and circuit-switched data services.

Examples of 2G systems are:

iDEN (Integrated Dispatch Enhanced Network) / ESMR / TETRA / TETRAPOL,

launched in 1994, use a channel bandwidth of 25 kHz and 12.5 kHz, and TDMA as

multiple-access technology (Time Division). TETRA and TETRAPOL were standards

used for police and emergency services.

GSM (Global System for Mobile), was launched in 1992 in Europe, and it has become

the most widely used cellular standard worldwide. It has a channel bandwidth of 200

kHz and uses TDMA.

CDMA one, using Code Division Multiple Access (CDMA) as multiple access

technology, was launched in 1996 in America. It uses a channel bandwidth of 1.25

MHz, and QUALCOMM registered its name for its original CDMA products.

2.5G

The 2.5G wireless technology generation is a step between 2G and 3G. It includes 2Gsystems that have been upgraded to support packet switched services. An example of this is

GPRS (Global Packet Radio Service), launched in 2001, which is seen as a GSM evolution,

having the same channel bandwidth as GSM (200 kHz) and TDMA as multiple access

technology.

2.75G

The 2.75G generation is an unofficial term to categorize wireless technologies that do not

meet the 3G requirements but were marketed as if they do. Examples of this standard

include: CDMA2001x (1xRTT), which is a direct evolution of CDMA one, and was launched in

2000. It uses a channel bandwidth of 1.25 MHz and CDMA as multiple access technology.

EDGE (Enhanced Data Rates for Global Evolution) is another example of 2.75G. EDGE was

launched in 2001-2002, it is an evolution of GSM towards 3G, having the same channel

bandwidth of 200 kHz and using the same multiple access technology as GSM.

Third Generation (3G)

Third Generation (3G) regroups digital networks that offer increased voice capacity and

provide higher data rates than 2G and 3G technologies.

WCDMA (Wideband Code Division Multiple Access), also known as UMTS (Universal Mobile

Telecommunications System), was deployed in Europe around 2002. It occupies a channel

bandwidth of 5 MHz, and uses wideband CDMA as the multiple access technology. On the

other hand, CDMA2000 1xEVDO (1x Evolution Data Optimized) was launched in 2002 in

America, as a data-optimized evolution of CDMA2000. It occupies a channel bandwidth of

1.25 MHz and also uses CDMA as multiple-access technology.

Other standards which have emerged for 3G include the ones listed in the next slide. In

general, there have been evolutions of others which were deployed prior to them.

Fourth Generation

Fourth Generation (4G) is a term used for International Mobile Telecommunications Advanced (IMT-Advanced), which is also known as Beyond 3G. 4G systems aim to upgrade

existing communication networks and are expected to provide a comprehensive and secure

IP-based solution where facilities such as voice, data and streamed multimedia will be

provided to users on an Anytime, Anywhere basis and at much higher data rates compared

to previous generations.

The baseband techniques for 4G are OFDM (Orthogonal Frequency Division Multiplexing), to

exploit the frequency-selective channel property; MIMO (Multiple Inputs Multiple Outputs) to

attain ultra-high spectral efficiency; and a turbo principle to minimize the required SNR

(Signal-to-Noise Ratio) at the receiver.

The principal 4G technologies include: adaptive radio interface; modulation, spatial

processing including MIMO; and relaying, including fixed relay networks (FRNs), and the

cooperative relaying concept, known as multi-mode protocol.

4G: OFDM

OFDM (Orthogonal Frequency Division Multiplexing) is a frequency-division multiplexing

(FDM) scheme utilized as a digital multi-carrier modulation method. A large number of

closely-spaced orthogonal sub-carriers are used to carry data. The data is divided into several

parallel data streams or channels, one for each sub-carrier. Each sub-carrier is modulated

with a conventional modulation scheme (such as Quadrature Amplitude Modulation, QAM or

Phase Shift Keying, PSK) at a low symbol rate, maintaining total data rates similar to

conventional single-carrier modulation schemes in the same bandwidth.The property of orthogonalityobserved in OFDM prevents demodulators from seeing

frequencies other than their own.

Some of the benefits of this technology in wireless communications are: high spectral

efficiency; more resilient to interference than other technologies; and lower multipath

distortion.

4G: MIMO-OFDM

Multiple-input and multiple-output or MIMO is the use of multiple antennas at both thetransmitter and receiver to improve communication performance. It is one of several forms of

smart antenna technology.

MIMO technology has attracted attention in wireless communications, since it offers

significant increases in data throughput and link range without additional bandwidth or

transmit power. It achieves this by higher spectral efficiency (more bits per second per hertz

of bandwidth) and link reliability or diversity (reduced fading).

When used in conjunction with OFDM, is called MIMO-OFDM. It will allow service providers

to deploy a Broadband Wireless Access (BWA) system with Non-Line of Sight (NLOS)

functionality. In addition, since data is transmitted both in the same frequency band and with

separate spatial signatures, this technique uses spectrum very efficiently.

WiMAX

WiMAX, or Worldwide Interoperability for Microwave Access, is a telecommunications

technology which enables wireless transmission of voice and data in two ways: point-to-point

links and full mobile access. Limited availability of spectrum worldwide makes mobile WiMAX

a particularly attractive technology thanks to an elaborate air interface (Scaled-OFDMA)

combined with high modulation schemes (up to 64QAM) and smart antennas (dynamic

bemforming, MIMO), all contributing to provide mobile users with an enhanced experience of

high data rate services such as web browsing or video streaming. In addition, Mobile WiMAX

brings us one step nearer to the convergence of fixed and mobile broadband access by wayof a single and unique air interface and a network architecture based on an all-IP approach.

In a certain way, mobile WiMAX can be regarded as a complement to Wireless Local Area

Networks (WLAN), having comparable data rate with better radio coverage; and to 3G cellular

systems, improving the data rate at comparable coverage. Nevertheless, it has also been

considered as a competitor to both technologies.

LTE provides downlink peak rates of at least 100Mbit/s, 50 Mbit/s in the uplink and RAN

(Radio Access Network) round-trip times of less than 10ms.

LTE FeaturesLTE has the following features defined in the standard:

Data rates

In the uplink, it is estimated a data rate of 50 Mbps, whereas twice this data rate for the

DL; i.e. 100 Mbps. Both FDD (Frequency Division Duplex) and TDD (Time Division

Multiplex) modes are supported.

Bandwidth

A flexible carrier bandwidth is anticipated for LTE, from 1.4 MHz to 20 MHz.

Goals

LTE has been designed to improve spectral efficiency while maintaining low cost, as

well as to improve service offering. The idea is to make use of new spectrum and

reformed spectrum, ensuring a much better integration with other wireless standards.

Architecture

It uses EPS (Evolved Packet System) and comprises E-UTRAN (Evolved UTRAN) on

the access side and EPC (Evolved Packet Core) on the core side. Advantages

LTE has higher throughput, low latency, plug and play, FDD and TDD in the same platform,

improved end-user experience and simple architecture resulting in low operating

expenditures; seamless support connection to existing networks such as GSM, cdmaOne, W-

CDMA (UMTS), and CDMA2000.
