The latest developments in wireless networks and services require advanced and comprehensive converged network testing capabilities - IXIA IxCatapult can meet this need.
With the advent of the 3rd Generation Partnership Project (3GPP) standard, Long Term Evolution (LTE) wireless technology will in fact become a wireless network solution for almost all wireless carriers. Compared to the current 3G network capacity and speed, LTE is more than 100 times more, with lower latency and a flexible spectrum ranging from 1.4 to 20 MHz. The "4G" network is a pure IP infrastructure that will become the mainstream of the market and replace the current wireless deployment and some wired networks.
Future wireless networks will support advanced applications that help improve connectivity and efficiency, such as smart phones, laptops and other similar tools and devices. As LTE continues to grow, the proportion of wireless traffic flowing into the core of the Internet will also increase.
3G networks will enter a large-scale deployment phase worldwide. At the same time, smartphones are increasingly becoming a development goal for rich media applications, allowing computing operations that were originally limited to workstations to be carried out on the move. The explosive growth of social networks will make wireless traffic grow exponentially. The worldwide 4G LTE wireless technology has firmly set foot on the journey. With the advent of 4G wireless applications, the world will shrink at a faster rate, attracting users in a new and powerful way. We are heading for a world that never stops and is always connected. Interactive rich media mobile applications will become the norm and will add tremendous value from hyperinteractivity.
2 Future developmentIf operators want to show the infinite prospects of a completely IP-based flat network, then the transition from 3G networks and wired networks to 4G technology is a necessary move. To provide the data-intensive multimedia applications that users need, they need to take advantage of the rapid development of these network infrastructures and LTE. To provide these services, operators must maintain a high quality experience (QoE) and high throughput levels. The 4G LTE technology revolution has begun with the core content of deploying secure, high-performance 3G and 4G wireless networks worldwide.
However, the transition from 3G to 4G wireless networks will bring unprecedented complexity. To reduce the risk of transition from 3G to 4G, every network equipment vendor and service provider needs to use structured planning, simulation and network testing tools. If you think through system thinking and adopt peer-to-peer quality assurance, 4G networks will introduce new models with higher performance bandwidth, greater component complexity and lower operating costs.
It must be tested by a large number of simulated users under actual flow conditions. Since multimedia and peer-to-peer applications account for most of the 3G/4G bandwidth usage, it is important to test the actual traffic simulation before deployment. This ensures that the network is properly configured and that there are no surprises in the deployed system. To validate next-generation converged networks, independent testing of wireless and wired devices, infrastructure subsystems, and complete point-to-point throughput is required.
The iPhone is a perfect example of a rich multimedia device, and it's really just the tip of the iceberg. Wireless and wired networks must advance and form iPhone-based traffic to ensure a balanced quality experience for all network users.
3 user issuesThe rapid development of 4G technology has brought many problems to telecom equipment manufacturers (TEMs) and operators. Manufacturers and operators need to bring products to market as quickly as possible. When planning and implementing an LTE deployment, the TEM needs to deliver the product to the operator, enabling it to quickly enter the market with reliable high-performance LTE products, most likely those that can lock in the carrier's promise, so that it can build a solid and reliable The LTE network, while the first operators to operate will attract new users.
LTE network devices need to be compatible with previous technologies, and TEMs must have the ability to interoperate with other vendors' products without the use of intermediate devices. Operators must be able to accommodate products from different vendors to enable smooth interoperability within the network. Successful cross-radio access technology (IPAT) switching is critical.
With this interoperability, extreme testing of individual components and subsystems is required to ensure that the equipment is up and running. In recent years, the widespread use of the iPhone and explosive SMS activities have caused a lot of network downtime, which means that traffic patterns at peak times must be simulated. TEM and operators must also ensure that all users enjoy satisfactory Quality of Service (QoS) and Quality of Experience (QoE), as well as real-world multimedia user models to test highly complex mobility to ensure QoS and QoE standards. Implementation.
Actual capacity evaluation must be established during the development and evolution of wireless networks. In order to properly configure the network, testing the network in real user mix mode and high stress is critical. This allows the TEM to correctly describe the device capacity, while for the operator, it can guarantee the uptime of the network and maintain user loyalty.
4 IXIA LTE Test SolutionIXIA recently acquired Catapult CommunicaTIons to provide the best comprehensive wireless test solution. Through this acquisition, it became the sole supplier of next-generation test tools from the LTE edge to the IP core. These tools are necessary to deploy LTE devices and applications for wireless and wired networks. By providing unparalleled point-to-point LTE testing, TEM can produce proactive LTE equipment, and operators can ensure that users get a super experience from 4G networks. To achieve this goal, detailed verification of next-generation 4G network devices, smart user devices and rich media applications is required.
