  • Apple iPad mini vs. Apple iPad: Comparing Apple's tablets

    Apple has finally lifted the lid on one of the most widely rumoured products of the year, the iPad mini. The 7.9in screened tablet is the company's first foray into the smaller tablet market.

  • HTML5 is not a panacea: Magic Software

    HTML5 is widely expected to become the technology of choice for future mobile application development, as mobile platforms become increasingly fragmented, but the technology is not a panacea, according to David Akka, UK managing director of Magic Software.

  • Five things your CEO will love about the iPhone 4S

    The iconic Apple iPhone got an internal makeover but not much else this week, no radical redesign, no iPhone 5 name change. Fashion-conscious consumers weren't very happy, but iPhone-toting CEOs should be pleased with the iPhone 4S. They might even cheer Apple for leaving out a flashy upgrade.

  • Six new and rising hacker threats

    Hackers never sleep, it seems. Just when you think you've battened down the hatches and fully protected yourself or your business from electronic security risks, along comes a new exploit to keep you up at night. It might be an SMS text message with a malevolent payload or a stalker who dogs your every step online. Or maybe it's an emerging technology like in-car Wi-Fi that suddenly creates a whole new attack vector.

  • Ten useful Android tips for professional IT admins

    Good news for network administrators, tech support staffers and other IT pros who use Android smartphones: There are hundreds of Android apps designed to help you get your work done faster, better and best of all remotely.

  • Four technologies for faster broadband in 2011

    A number of different technologies are being developed or improved to offer higher speeds for fixed and mobile broadband networks, as operators are preparing to compete with each other and carry video traffic in 3D and at higher resolutions, which is expected to happen in the coming year.

  • Simple guide to games on Windows Phone 7

    Gaming is obviously a huge draw on consumer smartphones. Games are the largest category of apps on the iPhone and a major area of growth for Android handsets, and phone gaming in general is arguably the largest growing segment in the game industry.

  • What is 4G? WiMax and LTE don't qualify

    If someone is trying to sell you 4G wireless these days, don't believe them. The truth is, neither WiMax nor LTE (Long-Term Evolution) qualify as 4G (fourth-generation) technologies, according to the International Telecommunication Union Radiocommunication Sector (ITU-R).

  • Best free WiFi security tools

    WiFi security has come a long way from the days when consumers used wireless routers with inadequate or no encryption, and overlooked the need to change default passwords for gateway access.

  • Apple iPhone iOS 4 update to fix reception issues

    After a quote from Steve Jobs, and a statement from Apple attempted to gloss over the antenna reception issue plaguing the iPhone 4 launch as a "non-issue", it seems that Apple may actually be treating it as a real issue - at least internally. There are reports that an update to the iOS 4 firmware could come as early as next week to address the problem.

Layered view of QoS issues in IP-based mobile wireless networks

The concept of 3G networks is based on an all-IP architecture supporting voice, video and data, and is driven by the needs for more bandwidth, more network capacity, and new radio spectrum. This gives rise to the need for performance enhancements and QoS guarantees in wireless networks. Internet Engineering Task Force (IETF) has defined QoS as a service agreement (or a guarantee) to provide a set of measurable networking service attributes, including end-to-end delay, delay variation (jitter), and available bandwidth.

Data Technologies in 3G Access Networks

Service providers are moving toward a model where anything that can be performed on a current IP network today, can be performed on a 3G wireless network. Mobile operators, specifically, are moving away from running packet-switched services over TDM networks, and running data over an efficient and cost effective data-focused infrastructure. This paper outlines the evolution of wireless technology, standards and networks with a focus on the data access network infrastructure as carriers migrate from 2G to 3G. It also details how Ciena's DN 7000 Series cost-effectively supports these access networks and helps facilitate the overall network migration from ATM to IP/MPLS.

High Speed Packet Access Solution

The volume of IP (Internet Protocol) traffic has already exceeded that for circuit-switched traffic in most fixed networks. The same change will happen in mobile networks as new IP-based mobile services, such as video news bulletins, downloading music or checking bus arrivals, become available and are used by more people in their daily communications.
