  28. Future Technologies in Access Network/Fixed Line • Fixed network - ultra-fast broadband • From copper to fiber optics • Not only the Internet, but also television and telephony are becoming increasingly IP-based. • Bigger screens and higher resolutions mean increasingly large quantities of data. • developing the latest technologies, such as Fibreto the Street (FTTS), is the solution to meet the growing need for bandwidth. • In the future, these technologies will be able to offer bandwidths of up to 100 Mbit/s, rising to 500 Mbit/s or more within a few years. • Fibre-optic network Into the home (Fiber to the x (FTTX)) • bringing fibre optics all the way into homes and businesses – • The fibre-optic cables have an almost unlimited data transmission capacity. 

  29. Optical Fiber Fiber to the x (FTTX) • is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last miletelecommunications. The term is a generalization for several configurations of fiber deployment, ranging from FTTN (fiber to the neighborhood) to FTTD (fiber to the desktop).

  30. FTTX architectures vary – with regard to the distance between the optical fiber and the end-user. • The building on the left is the central office; the building on the right is one of the buildings served by the central office. Dotted rectangles represent separate living or office spaces within the same building.

  31. The telecommunications industry differentiates between several distinct FTTX configurations. • FTTN / FTTLA (fiber-to-the-node, -neighborhood, or -last-amplifier): Fiber is terminated in a street cabinet, possibly miles away from the customer premises, with the final connections being copper. FTTN is often an interim step toward full FTTH and is typically used to deliver advanced triple-play telecommunications services. • FTTC / FTTK (fiber-to-the-curb/kerb, -closet, or -cabinet): This is very similar to FTTN, but the street cabinet or pole is closer to the user's premises, typically within 1,000 feet (300 m), within range for high-bandwidth copper technologies

  32. FTTP (fiber-to-the-premises): This term is used either as a blanket term for both FTTH and FTTB, or where the fiber network includes both homes and small businesses. • FTTB (fiber-to-the-building, -business, or -basement): Fiber reaches the boundary of the building, • FTTH (fiber-to-the-home): Fiber reaches the boundary of the living space, such as a box on the outside wall of a home. Passive optical networks and point-to-point ethernet are architectures that deliver triple-play services over FTTH networks directly from an operator's central office.[1][2] • FTTD (fiber-to-the-desktop): Fiber connection is installed from the main computer room to a terminal.

  33. Future Technologies and Challenges in Mobile Networks

  34. Cellular Network Generations • It is useful to think of cellular Network/telephony in terms of generations: • 0G: Briefcase-size mobile radio telephones • 1G: Analog cellular telephony • 2G: Digital cellular telephony • 3G: High-speed digital cellular telephony (including video telephony) • 4G: IP-based “anytime, anywhere” voice, data, and multimedia telephony at faster data rates than 3G (to be deployed in 2012–2015)

  35. Evolution of Cellular Networks 1G 2G 2.5G 3G 4G

  36. 4G Definition • 4G is not one defined technology or standard, but rather a collection of technologies at creating fully packet-switched networks optimized for data. • 4G Networks are projected to provide speed of 100Mbps while moving and 1Gbps while stationary.

  37. 0G (Zero Generation Mobile System) • At the end of the 1940’s, the first radio telephone service was introduced, and was designed to users in cars to the public land-line based telephone network. • In the 1960’s, a system launched by Bell Systems, called, Improved Mobile Telephone Service (IMTS), brought quite a few improvements such as direct dialing and more bandwidth. The very first analog systems were based upon IMTS and were created in the late 60s and early 70s.

  38. 1G Technology • 1G refers to the first-generation of wireless telephone technology was developed in 1970’s. • 1G had two major improvements: • the invention of the microprocessor • the digital transform of the control link between the phone and the cell site. • Analog signal • Continuous in amplitude and time • Variations in the signal- disrupts over long distances

  39. 1G Technology • Simplest type to wireless data • Average between 4800 to 9600 bps • Advanced mobile phone system(AMPS) launched by the US is a 1G mobile system • 1G is based on FDMA, it allows users to make voice calls in one country

  40. Problems with 1G Technology • Poor Voice Quality • Poor Battery Life • Phone Size big • No security • Frequent Call drops • Limited Capacity • Poor Hand off reliability

  41. 2G Technology • Second generation 2G phones using global system for mobile communications ( GSM) developed in early 1980’s. • First used in the early 1990’s in Europe • Better quality & capacity - More people could use there phones at the same time • Digital Signals – consist of 0’s & 1’s

  42. Previous Technology - 2G • GSM provides voice and limited data services. • Uses Digital modulation for improved audio quality • Digital signal: – consist of 0’s and 1’s • 1.Low level, 2.High level, 3.Rising edge and 4.Falling edge

  43. Previous Technology - 2G • Digital data can be compressed and multiplexed much more effectively than analog voice encodings • Multiplexing -multiple analog message signals or digital data streams are combined into one signal • For 1 and 2G standards, bandwidth maximum is 9.6 Kbit/sec,

  44. Disadvantages in Previous Technology - 2G • Need to improve transmission quality • Cell towers had a limited coverage area • Abrupt dropped calls • Unable to support complex data such as Video • Limited System capacity • “Spotty” coverage

  45. 3G Technology • 3G networks provide the ability to transfer voice, data and non voice data ( music downloads, emails and instant messaging) over the same network simultaneously. • Delivers broadband capacity and support greater numbers of voice and data customers at lower incremental costs than 2G.

  46. Technology - 3G • Standards: W-CDMA –Wideband Code Division Multiple Access EVDO: Evolution-Data Optimized The idea behind is to have a single network standard instead of the different types adopted in US, europe and Asia.

  47. Advantages: • Less Complexity, Faster Transmission • Large Capacity and broadband capabilities • Allows the transmission of 384kbps for mobile systems and up to 2Mbps for stationary users • Increased spectrum efficiency –5Mhz • A greater number of users that can be simultaneously supported by a radio frequency bandwidth • High data rates at lower incremental cost than 2G–Global roaming

  48. Reasons for New Research • Even though 3G has successfully been introduced to mobile users, there are some issues that are debated by 3G providers and users. • High input fees for the 3G service licenses • Great differences in the licensing terms • 3G phones are expensive • High bandwidth requirement • Huge Capital

  49. Fourth Generation

  50. What is 4G? • Fourth Generation Technology • 4G, the successor of 3G • 4G Technology or mobile comm systems that are characterized by high-speed data rates at 20 to 100 Mbps, suitable for high resolution movies and television, virtual initial deployment took place in 2006 to 2010
