  • Conclusion

Wi-Fi exists in so many
products of so many types
  • Many thousands of Wi-Fi devices mobile handsets,
    consumer electronics, networking equipment, PCs
    and computing devices and other

...but more importantly because it
appears that most of us cant live without it
Review of WiFi technologies -
  • 802.11b is on its way to the past!
  • Most modern Wi-Fi devices operating at 2.4GHz
    support 802.11g/n (OFDM), 802.11b (CCK) 802.11
    (DSSS) rates
  • The problem is that the low rates supported by
    CCK and DSSS are incredibly wasteful of spectrum
  • Some in the industry would like to ban completely
    the use of CCK and DSSS, but a more likely
    scenario is that it is made optional over a
    period of time allowed to go gracefully

Review of WiFi technologies -
  • WLAN 802.11 a/n 5 GHz 20, 40 MHz rate from 54
    Mbit/s to 600 Mbit/s)
  • 802.11ac, the next generation of Wi-Fi is here
  • Similar to 802.11n but better
  • Voice/video/data for consumer/enterprise
  • Evolutionary extension of 802.11n for 5GHz
  • Plus MU-MIMO vehicle for standardised Suite-B
  • Similar range to 802.11n
  • Faster than 802.11n realistically up to 2.5
  • Wider bandwidth options in 11ac 80MHz, 160MHz,
    and 8080MHz
  • Multi-user MIMO in 802.11ac sends multiple frames
    to multiple receivers

Review of WiFi technologies 802.11ad
  • WLAN 802.11 ad use of 60GHz, very high rate
  • ( gt1Gb/s) , beam formed, room area networking
  • About 7 GHz of spectrum available (varies by
  • Can go very fast even with only one RF chain
  • Potential for lower cost and lower energy per bit
  • 5mm wavelength and multiple (lt64) antennas can
    beamform for more range less interference
  • Room area networking easily blocked by humans,
    whiteboards, books, wall concrete
  • Potential applications wireless docking ,
    wireless peripherals, Syncngo, HDMI replacement
    , WLAN applications so that our workplace of the
    future is wire free (except maybe the power

Review of WiFi technologies
  • WLAN 802.11ah focused on applications below 1
    GHz for lower power/rates longer range
  • Spectrum in Europe 868-868.6 MHz,
  • Channel width 1, 2, 4, 8, 16 MHz
  • Rate gt 100kb/s (less than traditional 802.11)
  • Range lt 1km
  • new functionality support for a large number of
    stations, power saving enhancements, channel
    access enhancements, throughput enhancements
  • Commercial chips from 2015.

Review of WiFi technologies 802.11af
  • 802.11af defines operations in TV White Space
    bands (the repacking of TV bands in many
    countries has resulted in opportunity for new
    unlicensed spectrum
  • New rules are being designed to protect existing
    users from interference from unlicensed devices
    (e.g. digital TV and wireless microphones)
  • Uses a database to avoid interfering with primary
    users geolocation data base contains info about
    protected users it will be able to authorise the
    use of a channel at a particular time, location
    power for unlicensed operation)
  • Spectrum 470-698 MHz (UHF), VHF varies by
  • Channel width 6, 7, 8 MHz (vs 20/40 MHz in
    802.11n), scaled to TV channel bandwidths
  • Rate Less than traditional 802.11 due to narrow
  • Range More (3.5x) than traditional 802.11 due
    to superior propagation of TVWS
  • Regulations are not yet in place in most/all
  • Likely some of todays TVWS will be allocated to
    cellular In Europe, more is being used for
    cellular and DTTV than expected

Review of WiFi technologies 802.11ax- HEW
  • 802.11 HEW SG has been discussing drivers,
    environments applications for Wi-Fi next gen
  • Increased usage of mobile devices in dense
    environments and outdoors
  • Evolution of Wi-Fi application
  • More uplink traffic

    public places, outdoor hotspots, home/apartments,
    campus, airplane/bus/train/ship
  • New applications small wireless docking, unified
    communications, display sharing, cloud computing,
    video distribution, Progressive streamingUser
    Generated Content (UGC) Upload Sharing,
    interactive gaming and real-time video analytics

My life without a Smartphone?
Mobile World
Review of mobile technologies (1)
  • Mobile access
  • 2G
  • GSM CSD (Circuit Switched Data) up/down 9.6
  • GSM CDPD (Cellular Digital Packet Data) up/down
    19.2 kbit/s
  • 2.5G GSM GPRS (General Packet Radio Service)
  • up/down 56-115 kbit/s
  • 2.75G GSM EDGE (Enhanced Data Rates for GSM
    Evolution) up/down 237 kbit/s
  • 3G
  • UMTS WCDMA up/down 0.4 Mbit/s
  • UMTS HSPA (High Speed Packet Access) up 5.8
  • down 14.4 Mbit/s
  • UMTS TDD up/down 16 Mbit/s
  • GSM EDGE Evolution up 0.7 Mbit/s, down 1.6

Review of mobile technologies (2)
  • 4G
  • HSPA up 5.8-168 Mbit/s, down 21-672 Mbit/s
  • LTE up 50-75 Mbit/s, down 100-300 Mbit/s
  • LTE Advanced up/d?wn 100 Mbit/s (movment) or up
    1000 Mbit/s (stationary)
  • 802.16e Mobile WiMAX up 17 Mbit/s, down 37
  • 802.16m Mobile WiMAX (WirelessMAN Advanced) up
    376 Mbit/s, down 365 Mbit/s
  • Mobile handsets available with combination of GSM
    900/DCS 1800/
    900(FDD VIII)/LTE 1800(FDD III)/
  • LTE 2100(FDD I)/LTE2600(FDD VII)
  • Europe has seen a significant technology shift in
    recent years, with the proportion of 3G handsets
    increasing sharply. From around a fifth of total
    handsets in 2008, 3G devices now account for over
    half of all devices in Europe, a figure that we
    expect to peak at almost 61 in 2015.
  • LTE devices today represent only a small
    proportion of devices, at just 0.3 at the end of
  • LTE network coverage slowly improves and the
    price of 4G devices declines further, LTE should
    account for 20 of total devices by 2017.

Review of mobile technologies (3)
  • Rolling out mobile broadband in Europe using the
    800MHz band will make a significant contribution
    to economic growth
  • BCG suggests it could add 119B to EU GDP in the
    period out to 2020 as well as contributing a
    further 23B to public funding during this
  • The GDP impact comes from a range of factors
  • the creation of new business activities
  • improved productivity for businesses accessing
    and using the internet
  • the revenues and network investment from the
    mobile operators themselves.
  • Additional challenges for countries who delay the
    release of spectrum to cause interference in
    neighboring countries.
  • Benefits will be substantially reduced if the
    countries with derogations delay releasing this
    spectrum until 2017, which could reduce
  • the overall GDP benefit in 2020 by 16B (a 13
    reduction compared to the base case) and the tax
    benefit by 3B.
  • the number of new jobs created would fall by
    67,000 and the number of number of new businesses
    by 26,000

More Powerful Smartphones
  • The European mobile industry is one of the most
    successful in the world and has a strong track
    record in innovation and developing new services.
  • Smartphones are becoming far more powerful than
    the desktops of just a few years ago.
  • Competition and price cuts have increased the
    affordability of mobile services for consumers,
    leading to penetration rates in terms of both
    unique subscribers and smartphones that are
    amongst the highest in the world.
  • EU institutions and the mobile industry have a
    common agenda namely building a Connected Europe
  • Encourages investment in mobile connectivity
  • Enables innovation in new content and services
  • Builds consumer confidence in mobile services and

Mobile Services and applications
  • More advanced computing capability and
    connectivity, typically include the features of a
    computer with those of another popular consumer
    device, such as a personal digital assistant
    (PDA), a media player, a digital camera, direct
    Wi-Fi, Bluetooth, SRD (5725-5875 MHz) and/or a
    GPS navigation unit
  • Later smartphones include all of those plus the
    features of a touchscreen computer, including web
    browsing, 3rd-party apps, motion sensors and
    mobile payment
  • Currently, about 80 of handset sales worldwide
    are for devices driven by Googles Android and
    Apples iOS mobile operating systems

Mobile services and applications (2)
  • Third Wave opens up opportunities for a range of
    new services
  • mCommerce ticketing, payments,access control,
  • mEducation learning solutions
  • mHealthcare remotely,wellness and prevention,
    chronic desease menagement, diagnosis
  • mAutomotive eCall
  • Smart Cities Climate Street, fire brigade,
    police, traffic management
  • mIdentity accessing personal data securely,
    banking and financial services, signing documents
    on the go, mobile voting, access to eGovernment
    services (e.g. pensions, social security
    payments), birth/life events registration (e.g.
    birth, death, marriage certificates), unlocking
    secure premises etc.

Mobile services and applications (3)
  • Mobile payments is a broad concept and it can
    refer to different things including
  • premium SMS based transactional payments
  • direct mobile billing
  • Mobile web payments (WAP)
  • contactless payments (Near Field Communication
    NFC payments)
  • One of the key enablers of mCommerce is
    SIM-enabled Near Field Communications
  • (NFC) - a contactless radio technology that can
    transmit data between two devices within a few
    centimetres of each other. NFC 13,56 MHz chips
    are now being embedded into mobile phones,
    enabling an array of new digital services
  • NFC mobile services deployed in a number of
    French cities (Nice, Strasbourg)
  • Swedish mobile operators Telia, Tele2, Telenor
    and Three have launched WyWallet

IMT devices for 2020 and beyond
  • The high-level requirements of future IMT devices
  • very high system capacity and extremely high
    data rates
  • massive deployment of ubiquitous machine-type
    devices connectivity
  • variety of applications and environments
  • reduced cost, best ever/better energy saving and
    system robustness
  • high-level of security
  • more efficient spectrum utilization
  • enhanced self-awareness and self-adaptability
  • very high mobility with a high level of user
  • very low latency and higher reliability

Impact of new legislation -
Directive 2014/53/EU
  • Facilitate access to market
  • 2014/53/EU Radio Equipment Directive
    (RED)Member states no longer required to notify
    interfaces which
  • Are covered by a Commission Decision under
    676/2002/EC (Radio Spectrum Decision), or
  • Correspond to a class of equivalent interfaces
    that can be used anywhere in the Union (specified
    via implementing act)
  • Manufacturers no longer required to inform Member
    State before placing on the market equipment that
    uses non-harmonised spectrum
  • Manufacturer to check in EFIS if frequencies are
  • Frequency power to be included in user
  • No Alert symbol
  • Requirements to be invoked as necessary ....can
    only load compliant software

Directive 2014/53/EU - Universal
  • Directive includes specific requirements for
    Universal Charger as the essential requirements
  • In particular, mobile phones that are made
    available on the market should be compatible with
    a common charger
  • Interoperability between radio equipment and
    accessories such as chargers simplifies the use
    of radio equipment and reduces unnecessary waste
    and costs
  • A renewed effort to develop a common charger for
    particular categories or classes of radio
    equipment is necessary, in particular for the
    benefit of consumers and other end-users

Directive 2014/53/EU- Radio receiver
and antenna requirements (1)
  • Increased emphasis on efficient use of spectrum,
    in particular by improving radio receiver
  • Clear scope (but still some boundaries purpose
    of spectrum use)
  • Technical support relating to performance of
    antennas of mobile phones
  • Sensitivity varies significantly between phone
  • Higher Performance antennas requirements (B2B)
  • Need to ensure it will not increase SAR exposure
    (vulnerable consumers)

Directive 2014/53/EU- Radio receiver
and antenna requirements (2)
  • Revision of Harmonised Standards to provide
    presumption of conformity with RTTE (RED) to
    ensure enhanced receiver requirements
  • A labelling scheme appeared more problematic
  • There was no clear consensus whether such a label
    would be well understood by consumers, although
    certain Member States considered that such a
    scheme would be important to improve transparency
    for consumers
  • Other member states pointed to network coverage
    as being a strong contributing factor to problems
    experienced by users, and emphasised the work
    undertaken in CEPT to harmonise the harmonisation
    of methods to assess licensing conditions for

State of play in the Republic of
Serbia (1)
  • In total revenues in the electronic
    communications in the RoS in 2013, the largest
    share in total income has been realized from the
    provision of mobile telephony services in the
    amount of 878 million EUR, which represents 57
    of total revenue.
  • The largest share in terms of investments in the
    telecom market in SEE went once again to mobile
    telephony with 60.4.
