EDGE is an upgrade to GPRS that allows higher data transmission rates for 2G and 2.5G cellular networks. It introduces a new modulation technique called 8-PSK that encodes 3 bits per symbol instead of 1, tripling the data capacity within existing GSM spectrum and infrastructure. No changes are required to core networks, only software upgrades to base stations. This allows peak data rates of 474 kbps, much faster than GPRS's 115-160 kbps. EDGE provides benefits to users like higher speeds for data and multimedia, as well as benefits to operators through improved spectral efficiency and low upgrade costs since it reuses existing network components.

This document discusses key performance indicators (KPIs) for monitoring base station subsystems in EGPRS networks. It introduces EGPRS technology and defines KPI groups for traffic, availability, accessibility, and quality. Laboratory measurements were conducted to examine which BSS KPIs best reflect network performance and end-user experience by comparing application throughput to KPI values. The results showed that RLC throughput accurately described FTP throughput under different radio conditions. Multiple KPIs should be used to analyze radio link quality as one KPI cannot fully capture end-user experience.

The document provides an overview of 4G LTE-Advanced technologies including carrier aggregation, coordinated multipoint operation, self-organizing networks, and inter-cell interference coordination. It discusses how carrier aggregation allows combining of multiple component carriers to increase channel bandwidth up to 100MHz. Coordinated multipoint operation helps improve cell edge performance through coordination between base stations. Self-organizing networks allow dynamic configuration and optimization of heterogeneous networks. Inter-cell interference coordination further improves performance through techniques like almost blank subframes.
Refarming 4 g
LTE Refarming techniques allow mobile network operators to improve the efficiency of their GSM and LTE spectrum usage by rearranging frequencies between the two technologies. There are two main types of refarming: one-off refarming permanently reallocates part of a spectrum block like 1800 MHz from GSM to LTE, while interim refarming temporarily reallocates portions of GSM spectrum as traffic decreases using methods like sandwich frequency allocation that interleaves LTE and GSM bands. Refarming the 1800 MHz band currently used for 2G to 4G LTE can help operators address coverage holes and complement their main 4G spectrum at lower cost due to existing infrastructure.

This document discusses the Edge technology which improves upon existing GPRS services. It does so through implementing changes at the physical layer and MAC/RLC layers. Specifically, it introduces a new 8PSK modulation technique, additional modulation coding schemes, and other enhancements like resegmentation of packets and larger transmission windows. This allows Edge to achieve data rates of up to 384 kbps, offering a substantial improvement over GPRS's maximum of 160 kbps.
Gsm and edge
This document summarizes GSM and EDGE transmission. It describes how GSM is a digital cellular standard that uses digital modulation to provide voice and data services. It then explains the channel encoding, convolution encoding, interleaving, multiplexing, and GMSK modulation used in GSM transmission. EDGE is introduced as an enhancement to GSM that increases data rates up to 384 kbps using 8-PSK modulation. The key benefits of EDGE for users and operators are also highlighted.
GPRS
This research paper summarizes the principles and use of GPRS (General Packet Radio Service) as a 2.5G mobile data system and transition technology towards 3G networks. It describes how GPRS allows packet data transmission within existing 2G GSM infrastructure at moderate bit rates. It also discusses GPRS limitations and security aspects. Finally, it introduces EDGE as an enhanced version of GPRS that achieves higher speeds and concludes that GPRS/EDGE serves as an important transition technique towards 3G networks like UMTS since existing GSM infrastructure can be reused.
Enhanced Data rates for Global Evolution (EDGE)
Mobile users continue to demand higher data rates. With the continued growth in cellular services, laptop computer use and the Internet, wireless network providers are beginning to pay an increasing amount of attention to packet data networks. Enhanced Global Packet Radio Service (EGPRS) offers a substantial improvement in performance and capacity over existing GPRS services, in return for a relatively minimal additional investment. EGPRS, commonly called EDGE, achieves these enhancements to the GPRS system primarily by implementing changes to the Physical layer and to the Medium Access Control/Radio Link Control (MAC/RLC) layer. The significant improvements are a new modulation technique, additional modulation coding schemes, a combined Link Adaptation and Incremental Redundancy technique, re-segmentation of erroneously received packets, and a larger transmission window size.

Voice oriented data communication
The document discusses the evolution of voice services from 1G to 4G networks. It describes how voice capacity and quality have improved over generations as new speech codecs were introduced, such as the full rate codec in 2G GSM, the high-rate codec in 2G, and the adaptive multi-rate codec in 2.5G GSM which doubled voice capacity. Voice over LTE is then introduced, which allows transmission of voice over IP networks using codecs to encode voice into packets for delivery over LTE networks.
Wireless gateways and mobile appl. servers
A wireless gateway routes packets between networks and can be implemented through software, hardware, or a combination. It provides wireless access point, routing, and firewall functions. A wireless gateway also performs DHCP services to dynamically distribute network parameters. There are simple gateways connected to cable modems and more complex gateways with built-in modems. A mobile application server makes backend systems accessible to mobile apps, similar to web servers. It provides features like data routing, authentication, offline support, and security through data encryption. Mobile application servers can be deployed on-premise or in the cloud.
Internet protocol security
Ipsec is a suite of protocols that protects data as it travels over unsecured networks. It works by encrypting information through encapsulation at the network layer. Ipsec provides authentication to verify senders, integrity to ensure messages are not altered, and confidentiality by concealing message content. It uses Encapsulating Security Payload and Authentication Header to ensure data confidentiality, integrity, and authentication. Ipsec can operate in transport or tunnel mode, with tunnel mode being more secure by encrypting both the IP header and payload.
Wireless lan security
This document discusses wireless network security. It outlines uses and benefits of wireless networks, but also security issues like war driving and rogue networks. It evaluates potential security solutions like MAC address filtering, changing the SSID, and WEP encryption. However, it concludes that while wireless networks are convenient, current security measures are insufficient for sensitive environments given vulnerabilities like WEP attacks and the sharing of encryption keys across networks. Improved security is needed as wireless adoption increases.
Wtls
The document discusses WTLS (Wireless Transport Layer Security), which provides security for wireless communication through cell phones. WTLS is needed to securely enable e-commerce, online banking, and other internet activities via cell phones. It functions similarly to TLS/SSL by providing data integrity, privacy, authentication, and protection against denial-of-service attacks. WTLS specifications include full and abbreviated handshaking protocols to securely establish connections, as well as alert, cipher specification, and record protocols to protect the transmission of data.
Wap wml-6
This presentation discusses security for the Wireless Application Protocol (WAP). It covers security basics like authentication, confidentiality and encryption. It then discusses how security is implemented at the link layer and application layer in WAP. At the application layer, WTLS provides security for WAP applications, while SSL can be used for internet connections. Different trust models for WAP gateways hosted by operators or content providers are presented. The WAP Identity Module (WIM) provides cryptographic operations and secure storage of keys. Access control and digital signatures help provide authorization and non-repudiation in WAP.
Data (1)
This document discusses data recovery processes and quality of service (QoS). It begins by classifying different types of failures that can occur, such as transaction failures, system crashes, and disk failures. It then describes the ARIES recovery algorithm, which consists of analysis, redo, and undo phases. Log-based recovery using undo and redo operations on the log is explained. Checkpointing is discussed as a way to streamline recovery. QoS is defined as the ability to provide different priorities and guaranteed levels of performance. Factors that can affect QoS for mobile networks are also outlined.
Mc
The document discusses security issues related to the Wireless Application Protocol (WAP). It describes the WAP architecture and layers, including the Wireless Transport Layer Security (WTLS) protocol used for encryption over wireless networks. A major security issue arises from the need to translate between WTLS and TLS at the WAP gateway, where content is briefly exposed in plaintext. To address this "WAP gap", options include protecting the gateway or moving it inside the corporate firewall. The document also notes the importance of application-level security beyond transport security using techniques in the WML specification and WMLScript Crypto API.
Mc seminar
Query processing involves translating queries into a form the database management system can use to efficiently retrieve the desired data. It includes parsing queries, translating them into relational algebra expressions, optimizing the query plan to minimize costs, and executing the optimal plan. The key steps are translation, optimization of multiple evaluation plans based on statistics, and execution of the selected lowest-cost plan to return results. Query processing is crucial for large databases to return results in a timely manner.
Mcseminar
This document discusses various transport layer protocols for mobile networks. It begins with an overview of TCP and UDP, and then describes several strategies for improving TCP performance over mobile networks, including indirect TCP (I-TCP), snooping TCP, and Mobile TCP. It also discusses congestion control strategies like slow start and fast retransmit. Overall, the document analyzes how TCP can be optimized through techniques like connection splitting, buffering, and selective retransmission to better accommodate the characteristics of wireless networks.
Middleware final
This document discusses middleware, including its history, types, advantages, and future. Middleware sits between layers of software to allow different applications to work together seamlessly. There are four main types: transaction processing, remote procedure call (RPC), message-oriented middleware (MOM), and object request broker (ORB). Middleware provides benefits like centralized management of transactions, hiding operating system details, and asynchronous communication between clients and servers. The future of middleware and enterprise application integration is promising, with the market expected to grow substantially in the coming years.
Web services
Web services allow software applications to communicate over the internet through standardized web protocols like XML, SOAP, WSDL and UDDI. A web service is a software application identified by a URI that can be invoked by other applications over HTTP. Web services use XML to encode communications and do not depend on any particular operating system or programming language, allowing different systems to communicate. The basic web services platform uses XML and HTTP, with components like SOAP for message transfer, WSDL for describing services, and UDDI for discovery of services.
Wap wml
This presentation discusses security for the Wireless Application Protocol (WAP). It covers security basics like authentication, confidentiality and encryption. It then discusses how security is implemented at the link layer and application layer for WAP. This includes the use of WTLS and SSL to provide security between the gateway and servers as well as the use of the Wireless Identity Module (WIM), WMLScript and access control to provide authorization and non-repudiation. Finally, it summarizes different WAP security models depending on whether the gateway is hosted by the operator or content provider.
Vpn 3
Virtual private networks (VPNs) allow employees to securely access a private company network from remote locations over the public Internet. VPNs use encryption and tunneling protocols to create a private network within the public network. This allows employees to access resources as if they were on the private company network while gaining the flexibility and reduced costs of using the public Internet. However, VPNs also come with security risks and performance depends on factors outside of an organization's control.
Vpn
Virtual private networks (VPNs) allow remote access to private networks over public telecommunications networks like the Internet. VPNs use encryption, authentication, and tunneling protocols to securely connect remote users to a private network. They provide cost savings over traditional private networks by reducing equipment and maintenance costs while increasing flexibility and scalability. However, VPN performance depends on public networks and proper security deployment is required to mitigate risks.
Seminar gprs
GPRS is a packet-based mobile data service on GSM networks that provides higher data rates and more efficient data transfer than traditional GSM networks. GPRS uses a packet-switched technology and radio resources are shared dynamically across users. The key network elements that support GPRS include the SGSN which manages data sessions and mobility, and the GGSN which connects the GPRS network to external data networks. GPRS enables numerous mobile data applications like web browsing, email, and remote access by supporting common internet protocols and billing based on data usage rather than connection time.
Seminar mc palm
Palm OS is a mobile operating system initially developed by Palm in 1996 to run on Palm PDAs. It is designed for touchscreen devices with small screens, limited processing power and memory. The OS uses a 32-bit architecture and is optimized for resource-constrained hardware. It utilizes dynamic RAM for temporary storage, storage RAM for persistent user data storage, and a database manager to access records stored in RAM in a way similar to accessing files on a hard disk. Applications are single-threaded and event-driven. Development tools include Code Warrior and the Palm SDK.
Guided media
This document summarizes different types of guided transmission media, including coaxial cable, twisted pair, and optical fiber. It provides details on their characteristics, components, bandwidth capabilities, applications and advantages. Guided media uses conductors like wires or fiber optic cables to transmit signals from sender to receiver. Examples given are coaxial cables, twisted pair wires, and optical fiber.
12 mobile os
The operating system manages computer hardware resources and provides common services that allow application software to function. It acts as an intermediary between applications and hardware, allocating memory and handling input/output. Common operating systems include versions of Unix, Mac OS X, Chrome OS, Windows, and for mobile - Android, iOS, BlackBerry OS, Symbian OS, webOS, and Windows Phone.
10 mobile agents
Mobile agents are software programs that can autonomously migrate between hosts in a network to perform tasks. They have intelligence, learn user behaviors, and can communicate and respond to changes in their environment. A mobile agent's code and execution state are transferred when it migrates, allowing it to resume tasks on new hosts and reduce network loads. However, mobile agents also present security risks if viruses are disguised as agents.

- 6. Implementation Of EDGE • No hardware or software changes to be made in GSM core networks, only base stations must be modified. • EDGE compatible transceiver units must be installed in Base Station Subsystem hardware. • Software upgrades to the Base Station Controller (BSCs) and Base Stations (BS). EDGE is just an “add- on” to the BSS. • A new modulation scheme “8-PSK” is introduced to provide high data rate and high spectral efficiency. 6
- 7. Reasons For Using 8-PSK • To achieve higher bit rates than that of GPRS, the existing GMSK modulation technique must be modified. • EDGE is specified to reuse the channel structure, width, coding and existing mechanism of GPRS. • The modulation technique used for EDGE i.e. “8-PSK” fulfills all those requirements. • This makes it possible to integrate new EDGE channels into an existing frequency plan of GSM network. 7

- 9. • The 8-PSK modulation is a method in which 1 symbol carries 3 bits of information. • The total data rate is therefore increased by a factor of three. • The distance between the symbols are shorter than that of GMSK.Hence increase the risk of misinterpretation of symbols. • Each set of bits is just one bit different from its neighbor. So if the radio receiver makes an error in reading the symbol, most likely this will result in only one bit being misinterpreted. 9

But GPRS has introduced Packet-Switched Data into GSM networks. • EDGE is an “add-on” to GPRS and can not work alone. • EDGE can transmit three times as many bits as GPRS during the same period of time. • GPRS allows average data rates of 115 Kbps and theoretically up to 160 Kbps whereas EDGE offers average data rate of 384 Kbps and theoretically up to 473.6 Kbps. 11
