Intro
The next-generation network is all about creating a common IP-based architecture. It delivers multiple services over many different access technologies, increasing flexibility and reducing overall cost. The next-generation network era brings with exciting possibilities for creating communications products and services that will revolutionize multiple industries.
Applications Of Next Generation Network
NGN Standards
Telephony Broadband & Mobile IPTV
Telephony
Voice Over Internet Protocol: VoIP systems usually interface with the traditional public switched telephone network (PSTN) for delivery of voice communication with reduced cost.
Advantages:
The ability to transmit more than one telephone call over the same broadband connection. Cost of Conference calling, call forwarding, automatic redial, and caller ID is near to zero. Secure calls using standardized protocols. Location independence. Video conversation, message or data file exchange in parallel with the conversation, audio conferencing, managing address books, and passing information about whether others are available to interested
VoIP challenges:
Available bandwidth Network Latency Packet loss Echo Security Reliability
Broadband & Mobile
WiMAX: Similar to WiFi but at higher speeds, over greater distances and for a greater number of users. WiMAX could potentially erase the suburban and rural blackout areas that currently have no broadband Internet access
iBurst: Wireless
access system subsequently adopted as the High Capacity. It provides wide-area broadband wireless data-connectivity for fixed, portable and mobile computing devices and appliances. The protocol is designed to be implemented with smart antenna array techniques to substantially improve the radio frequency (RF) coverage,
Commercial use:
Desktop modem with USB and Ethernet ports (with external power supply) Portable USB modem (using USB power supply) Laptop modem (PC card) Wireless Residential Gateway (WRG) in combination with Laptop modem
WiBro (Wireless Broadband):
Is a wireless broadband Internet technology WiBro is the South Korean service name for IEEE 802.16e (mobile WiMAX) international standard. WiBro base stations will offer an aggregate data throughput of 30-50 Mb/s and cover a radius of 1-5 km allowing for the use of portable internet. It will provide mobility for moving devices up to 120 km/h (74.5 miles/h) compared to Wireless LAN having mobility up to walking speed and Mobile Phone having mobility
HiperMAN (High Performance Radio Metropolitan Area Network):
It provide a wireless network communication in the 2 - 11 GHz bands across Europe and other countries. HiperMAN is a European alternative to WiMAX and WiBro. It aims for providing broadband Wireless Internet access, while covering a large geographic area. It is optimized for packet switched networks, and supports fixed applications, primarily in the residential and small business user environments.
It offers various service categories, full Quality of Service, fast connection control management, strong security, fast adaptation of coding.
Mobiles 4G(Beyond 3G): A 4G system will be able to provide a comprehensive IP solution where voice, data and streamed multimedia can be given to users on an "Anytime, Anywhere" basis, with higher data rates than previous generations. 4G will be capable of providing between 100 Mb/s and 1 GB/s speeds with premium quality and high security. But Many companies have taken selfserving definitions about 4G to suggest
Objectives:
High network capacity: more simultaneous users per cell A nominal data rate of 100 Mb/s while the client physically moves at high speeds relative to the station, and 1 GB/s while client and station are in relatively fixed positions. A data rate of at least 100 MB/s between any two points in the world. Smooth handoff across heterogeneous networks. Seamless connectivity and global roaming across multiple networks. High quality of service for next generation multimedia support
Flash-OFDM (Fast latency Access with Seamless Handoff Orthogonal Frequency Division Multiplexing): Flash-OFDM has generated interest as a packet switched cellular bearer, where it would compete with GSM and 3G networks. The Standard Includes: • Peak download rates of 326.4 MB/s for 4x4 antennas, 172.8 MB/s for 2x2 antennas for every 20 MHz of spectrum. • At least 200 active users in every 5 MHz cell. (i.e., 200 active data clients)
Optimal cell size of 5 km, 30 km sizes with reasonable performance, and up to 100 km cell sizes supported with acceptable performance Co-existence with legacy standards (users can transparently start a call or transfer of data in an area using an LTE standard, and, should coverage be unavailable, continue the operation without any action on their part using GSM/GPRS or W-CDMAbased UMTS or even 3GPP2 networks such as CDMA One or CDMA2000) Supports MBSFN (Multicast Broadcast Single Frequency Network). This feature can deliver services such as Mobile TV using the LTE infrastructure.
IPTV IPTV (Internet Protocol Television): is a system where a digital television service is delivered using Internet Protocol, which may include delivery by a broadband connection.
For residential users, IPTV is often provided in conjunction with Video on Demand and may be bundled with services such as Web access and VoIP. Video content is typically compressed using either a MPEG-2 or a MPEG-4 codec. Because IPTV uses standard networking protocols, it promises lower costs for operators and lower prices for users. IPTV uses a two-way digital broadcast signal sent through a switched telephone or cable network by way of a broadband connection and a set-top box programmed with software.
Summary
Next Generation Network (NGN) is the new generation of communication network architecture. Its principle is to use packet mode transmission technologies to transport all telecommunication services. Interfaces are separated from the different layers of the communication network to allow for a greater evolution of the network. The landscape of NGN changes constantly to accommodate quickly evolving technologies, as well as new players, mergers and acquisitions.
