    broadband connections over long distances
  • IEEE 802.16e, mobility for subscribers,
    finalizing standards racing to prototypes

WiMAX and Wi-fi
  • What is Wi-fi,
  • Advantages of Wi-fi,
  • Comparison to WiMAX and Wi-fi

10
What is Wifi?
  • This is modern wireless technology of computers
    connection to the network or connecting them to
    the internet. Just with the help of this
    technology the internet gets mobile and gives the
    user the opportunity to be mobile both in the
    limit of a room and worldwide. Technology
    provides simultaneous work in the network of
    several dozens of the active users speed of
    information transmission for the final subscriber
    can reach 108Mbit/sec. Wi-Fi access is available
    for note-book and personal pocket computer,
    web-camera or wireless IP-telephone owners
    equipped with the proper module meeting the IEEE
    802.11 standard.

11
Advantages of Wi-fi
  • Absence of Wires
  • The network is based on wireless Wi-Fi
    technology which does not require using the
    telephone or any other lines of connection based
    on wires. Data transmission is carried out
    through air on a very high frequency which
    doesnt influence a man and does not create
    hindrances of electronic equipment.
  • Possibility of some mobility.
  • Since you are not tied up to wires, you can
    easily change location of your computer not
    worrying about connection withdrawal (in the
    cover area of access point).
  • High-speed access to internet
  • A high-speed access to internet is offered for
    network subscribers, speed of channel is
    108Mbit/sec. Meanwhile, there is no necessity for
    ringing up or connection defining, etc. You are
    always on-line and to be connected to internet it
    is just enough to open your browser.

12
Comparison to WiMAX and Wi-fi
  • IEEE Standards
  • Wi-Fi is based on IEEE 802.11 standard where as
    WiMAX is based on IEEE 802.16. However both are
    IEEE standards.
  • Range
  • Wi-Fi typically provides local network access
    for around a few hundred feet with speeds of up
    to 54 Mbps, a single WiMAX antenna is expected to
    have a range of up to 40 miles with speeds of 70
    Mbps or more. As such, WiMAX can bring the
    underlying Internet connection needed to service
    localWi-Fi networks.
  • Scalability
  • Wi-Fi is intended for LAN applications, users
    scale from one to tens with one subscriber for
    each CPE device. Fixed channel sizes (20MHz).
  • WiMAX is designed to efficiently support from
    one to hundreds of Consumer premises equipments
    (CPE)s, with unlimited subscribers behind each
    CPE. Flexible channel sizes from 1.5MHz to 20MHz.

13
Comparison to WiMAX and Wi-fi
  • Bit rate
  • Wi-Fi works at 2.7 bps/Hz and can peak up to 54
    Mbps in 20 MHz channel.
  • WiMAX works at 5 bps/Hz and can peak up to 100
    Mbps in a 20 MHz channel.
  • Quality of Service
  • Wi-Fi does not guarantee any QoS but WiMax will
    provide your several level of QoS.
  • As such, WiMAX can bring the underlying Internet
    connection needed to service local Wi-Fi
    networks. Wi-Fi does not provide ubiquitous
    broadband while WiMAX does.

14
WiMAX and 3G
  • What is 3G,Features of 3G,Comparison to WiMAX

15
What is 3G?
  • A radio communications technology that will
    create a "bit pipe" for providing mobile access
    to internet-based services. It will enhance and
    extend mobility in many areas of our lives.

16
Features of 3G
  • Phone calls/fax
  • Global roaming
  • Send/receive large email messages
  • High-speed Web Navigation/mapsVideoconferencing
  • TV streaming
  • Electronic agenda meeting reminder.

17
Comparison to WiMAX
  • WiMAX (Worldwide interoperability for Microwave
    Access) is  a broadband wireless access
    technology that can deliver data speeds much
    higher than 3G, and at chepaer rates. Till
    recently, 3G has been the only way to deliver
    broadband connectivity to mobile phones.

18
Comparison to WiMAX
  • A typical mobile WiMAX network can deliver up to
    15 Mbps within a 3-km cell radius, compared to 3G
    speeds of 2-2.4 Mbps (for CDMA 2000 and WCDMA).
    Or in other words, if you want to download a
    full-length movie onto your mobile, it will take
    64 minutes on a 3G connection, but less than nine
    minutes with WiMAX.

19
Comparison to WiMAX
  • 3G could drive a variety of applications on your
    handheld key among these will be video telephony
    and video conferenceing, mobile TV, interactive
    gaming, streaming video, music downloads and
    mobile TV. But WiMAX  is not just about data.
    Now, there is a greater push offering voice also
    on a WiMAX platform. Many, including Nortel, are
    conducting trials of mobile WiMAX.

20
Comparison to WiMAX
  • 3G has the potential to disrupt the Indian
    telecom business model as WiMAX spectrum licences
    could be far cheaper than 3G or even the GSM or
    CDMA liceces that have been awarded so far.
    Globally, this has been the case. In Singapore,
    for instance, the highest amount paid for
    broadband wireless spectrum was 2.27 million,
    compared to 100 million for 3G. According to
    telecom regulator Trai's recommendations, the
    minimum bid amount for a pan India WiMAX presence
    is Rs.142 crore. Compare this with the Rs.1,050
    crore base price for similar deployment of 3G
    services almost eight times higher.

21
Comparison to Wimax
  • WiMAX was designed primarily for data and is
    limited in its ability to carry voice. On the
    other hand, 3G is good for voice, but cannot
    match the data speeds that WiMAX supports.

22
Wimax Mobility
  • Broadband Mobility,Portable and Full Mobility
    Scenario,Features and Advantages

23
Broadband Mobility
  • Broadband Wireless Mobility is a solution for
    service providers and carriers, that is
    interoperable with their existing networks and
    that can augment coverage and service to
    end-users.
  • Because it is an IP-based solution, it can be
    integrated with both wireline and 3G mobile
    networks.

24
Portable and Full Mobility Scenario
  • Broadband Wireless Mobility mainly aims to allow
    service providers to reach nomadic and mobile
    customers equipped with portable devices and
    allow outdoor roaming across geographical areas
    of coverage.

25
Portable and Full Mobility Scenario
26
Portable and Full Mobility Scenario
  • Broadband Wireless Mobility uses the Mobile WiMAX
    standard that mainly enables the delivery of
    high-bandwidth services with an array of
    multimedia features.
  • Users can then enjoy a wireless DSL service that
    is accessible in moving vehicles up to 75 mph
    with a data rate of 5Mbps at the range of 1-3
    miles.

27
Features and Advantages
  • Portable high speed data service
  • Wider range of coverage (1-3 miles radius)
  • Supports mobility at 75mph
  • High throughput (30Mbps at 10 Mhz bandwidth)
  • Potential for roaming in larger scale
  • Flexible
  • Cost effective

Quality of Service
  • Network Quality of Service is determined by both
    Physical and Market characteristics.
  • Port Blocking
  • Traffic Structuring

32
Wimax and 3G
  • Although Wimax technology will be capable of
    providing VOIP services, 3G technologies will
    remain much more efficient in the use of bandwith
    for voice transport. Wimax providers have the
    ability and are allowed to offer services at high
    levels of mobility.
