  1. 1. * What makes it work?
  2. 2. * Mobile technology is exactly what the name implies - technology that is portable. Examples of mobile IT devices include:* laptop and netbook computers* palmtop computers or personal digital assistants* mobile phones and smart phones* global positioning system (GPS) devices* wireless debit/credit card payment terminals *
  3. 3. * Traditionally, access to the Web has been via fixed-line services. However, the Web is becoming more accessible by portable and wireless devices and in 2008 mobile access to the Internet exceeded desktop computer-based access for the first time.* The shift to mobile Web access has been accelerating with the rise since 2007 of larger multitouch smartphones, and of multitouch tablet computers since 2010. *
  4. 4. * Currently Over 3 billion mobile phone users, estimated to grow to 5 billion in 2010 * Growing dependence on mobile connectivity * Demand for Data mobility * Significant increase in Data, video and application development* Traffic growing exponentially due to consumer demand for mobile data services for e-mail, text messaging, web access etc* Push for more bandwidth accelerated by new handsets such as iPhones that combine digital media entertainment with web based applications *
  5. 5. * Mobile devices can be enabled to use a variety of communications technologies such as:* wireless fidelity (Wi-Fi) - a type of wireless local area network technology* Bluetooth - connects mobile devices wirelessly* ‘Third generation (3G), (now 4G)* Global system for mobile communications (GSM)* General packet radio service (GPRS)* Data services - data networking services for mobile phones* Dial-up services - data networking services using modems and telephone lines* Virtual private networks - secure access to a private network *
  6. 6. ** The GSMA’s industry-defining event, Mobile World Congress, again shattered attendance records as more than 67,000 attendees showcased how they are Redefining Mobile.* This year’s exciting event, hosted in the Mobile World Capital Barcelona, featured attendees from 205 countries were treated to a wealth of learning and networking opportunities; product showcases and announcements; inspiration and innovation* Mobile World Congress 2011 was by all accounts a record-breaking year: * Highest-ever total attendance: more than 60,000 * Largest-ever senior-level audience: more than 58% * Highest-ever number of CEOs in attendance: more than 3,000 * Largest-ever number of exhibitors: 1,400 * Largest-ever number of press: 2,900+ press members representing 1,500 media outlets * Largest-ever gathering of Mobile App Developers: more than 12,000

  8. 8. ** Mobile broadband works on the same technology on which cell phones work. It is all about the radio frequencies and waves.* The cell phone radio towers and cell phones send packets of information back and forth through radio waves. For cell phone broadband, the information packets can be data like streaming video, music files, web pages and e-mails.* Basically, there are two technologies which are used to operate the networks of cell phones- CDMA (Code division multiple access) and GSM (Global System for mobile communications).* GSM is quite popular in Asia and Europe while CDMA is popular in the US.* There are quite major differences between these systems and the way that they operate. Both of these use different types of algorithms which allow several cell phone users to share the same frequency without interfering the usage of others.* Mobile broadband is known as third generation mobile technology or 3G.* CDMA and GSM both have their 3G technology solutions for allowing users to deliver high speed access to the internet on mobile devices.
  9. 9. * The rise in data traffic carried over wireless networks has taken many by surprise.* Industry analysts anticipate that data volumes will grow at an accelerating rate based on this broader range of broadband data services.* At the same time, revenue per megabyte continues to fall, driven down by increasing competition and the introduction of flatrate pricing.* To remain competitive, mobile operators must be prepared to provide a network that can not only meet bandwidth demand, but also deliver a healthy profit margin. To achieve this goal, new technology is required to translate this significant rise in traffic into revenue opportunities. *

  11. 11. • The Mobile Backhaul network : • Is the critical link between the mobile subscriber and the network or the Internet • Links the remote base stations and cell towers to the mobile operators core networks • Provide access to both the voice network and the internet * Copper FiberWireless handset Carrier Base Station
  12. 12. * New services provide additional capabilities but require more bandwidth.* T1/E1 TDM Backhaul Circuits traditionally used are ideal for carrying high-value voice services but are not optimized for high bandwidth data services.* Backhaul links are becoming congested *
  13. 13. *
  14. 14. * With mesh networking, access points are connected wirelessly and exchange data frames with each other to forward to/from a gateway point.* Since a mesh requires no costly cable constructions for its backhaul network, it reduces total investment cost.* Mesh technology’s capabilities can boost extending coverage of service areas easily and flexibly. *

  16. 16. * In 2010, hundreds of wireless LAN access points incorporating the technology were installed in the commercial shopping and entertainment complex, Canal City Hakata, resulting in the successful operation of one of the worlds largest indoor wireless multi-hop backhauls.* The wireless network deploying over 200 access point devices built inside Canal City Hakata realizes a wireless multi-hop relay of up to 11 access points while delivering high bandwidth to end users. Actual throughput is double that of standard mesh network systems using conventional packet forwarding. *
  17. 17. * Ethernet is a family of computer networking technologies for local area networks (LANs) commercially introduced in 1980.* Systems communicating over Ethernet divide a stream of data into individual packets called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re- transmitted. *

  20. 20. * WDM – Wavelength Division Multiplexing* DWDM – Dense Wavelength Division Multiplexing* WDM is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e colours) of laserlight. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity.* DWDM increases the WDM signal within the 1550 nm band so as to leverage the capabilities (and cost) of existing networks. *In telecommunications and computer networks, multiplexing (also known as muxing) is a method by whichmultiple analog message signals or digital data streams are combined into one signal over a shared medium.The aim is to share an expensive resource.
  21. 21. * WDM systems are popular with telecommunications companies because they allow them to expand the capacity of the network without laying more fiber. By using WDM and optical amplifiers, they can accommodate several generations of technology development in their optical infrastructure without having to overhaul the backbone network. *
  22. 22. •Economic advantages of Ethernet and WDM will lead to its widespread use for mobile backhaul networks•Introduction of Ethernet and IP interfaces in mobile base stations and radio controller equipment•Migration of legacy TDM and SONET/SDH circuits to Carrier Ethernet Solutions and DWDM Solutions•There is Global acceptance of these new standards evidenced by their support and use by major hardware / software companies such as CISCO *

Worldwide M obile 1st M ile Backhaul Service Charges per Connection: • PDH (T1/E1 etc.) costs PDH and ATM over PDH vs New Wireline climb directly with bandwidth $40,000 $37,044 • Ethernet wire-line costs grow gently with $30,000 large bandwidth increases (Eth, DSL,Revenue PDH and ATM over PDH $20,000 PON, cable) New wireline $10,000 $6,887 $0 CY05 CY06 CY07 CY08 CY09 CY10 Calendar Year *
  24. 24. * Backhaul network implementation must be designed to support multiple mobile operators sharing the same cell tower.* Because cell tower sharing is a common practice in most countries today, it has become a business imperative that the fixed network operator must plan to serve multiple mobile operators from the same backhaul network.* According to industry estimates, more than 60 percent of all cell towers worldwide are shared by multiple mobile operators. *
