· Moving forward to LTE-Advanced with Heterogeneous Networks
Wireless technologies have evolved to provide mobile users higher data rates on wireless networks with seamless connection anytime and anywhere. Commercial HSPA+ and LTE networks serve the Smartphone and tablet users with faster wireless data communication, and upcoming LTE-Advanced technology targets even faster speeds, with up to 1Gbps, maximum downlink data rates. To achieve this dramatically faster wireless data communication, Carrier Aggregation, with the wider transmission bandwidths up to 100MHz, enhanced Multi Input and Multi Output (MIMO) with up to 8x8 signal processing, and other advanced technologies, will play an important role. In addition, Heterogeneous Network (HetNet) will provide new and advanced network topology, which moves wireless networks closer to mobile devices with various approaches including lower power small cells and relay nodes. Remote Radio Heads, Distributed Antenna System and Wi-Fi can also be the part of a HetNet, improving coverage, spectrum efficiency and data rates of the overall wireless service.
This paper will introduce HetNet with a comparison to traditional networks, describe its benefits, present the different elements including various types of cells (macro, micro, pico and femto), Remote Radio Head, and Distributed Antenna System. The paper will also address the test challenges of HetNet, and introduce broad and powerful Agilent Heterogeneous Network design and test solutions.
· RF Power Amplifier Design Series: Envelope Tracking Simulation and Analysis
Modern modulated signals have high peak-to-average power ratios (PAPR.) Power amplifiers that must amplify these high PAPR signals, if using a fixed bias, must be operated at relatively high output power back off, to avoid greatly distorting the signal when its envelope excursion is near its peak. However, the greater the amount of back off, the lower the efficiency of the power amplifier will be. Envelope tracking is a way of overcoming this issue, by allowing the amplifier’s drain bias to track the magnitude of the input signal envelope. When the input signal envelope is low, the drain bias can be reduced so the amplifier operates closer to its optimal efficiency point. This webcast will provide an overview of Envelope Tracking simulation and analysis.
· Multi-Standard Radio (MSR) Base Station Introduction and Measurement Challenges
Next generation base station (BS) transmitters, and receivers, will support wider bandwidths and include not only multiple carriers (MCs) of a single radio format, but also multiple formats in one transmitter path. As an example, GSM, W-CDMA and LTE MCs can be transmitted from a single MSR base station unit simultaneously. Having BS support multiple formats in a cellular network is important for network operators to save both BS size and cost: MSR BSs are expected to realize a smooth and seamless network migration from the currently deployed 2/3G radio formats toward 3.9G (e.g. LTE) and even 4G (e.g. LTE-Advanced) technologies through certain periods of time. While it will be beneficial for the network service providers and mobile subscribers alike, applying MSR MC configurations may possibly introduce some unexpected BS RF performance degradations: finding an effective way to test MSR BS is an essential portion to ensuring the successful cellular network migration to MSR BS. Release 9 of the 3GPP specification includes a series of documents, TS37 series, that focus on MSR BS conformance testing.These documents cover the MSR MC combinations of 3GPP FDD formats (e.g. LTE FDD, W-CDMA/HSPA and GSM/EDGE) and 3GPP TDD formats (LTE TDD and TD-SCDMA).
This paper discusses:
- An introduction to MSR technology
- MSR market overview
- New 3GPP MSR BS conformance test requirement summary
- Key challenges to test MSR BS
· LTE-Advanced Physical Layer Design and Test Challenges: Carrier Aggregation
Achieving the IMT-Advanced 4G target peak data rates of 1Gbps in the downlink and 500 Mbps in the uplink requires wider channel bandwidths than the maximum 20 MHz bandwidth that is specified in LTE release 8. In order to achieve those target peak data rates, LTE-Advanced extends LTE release 8 with support for carrier aggregation where two or more component carriers (CCs) are aggregated in order to support wider transmission bandwidths of up to 100 MHz. For most operators, however, 100 MHz contiguous bandwidth is hard to find in the available spectrum resources and, therefore, the ITU has allowed the use of non-contiguous carrier aggregation. In this case, the CCs can be non-contiguous in the same spectrum band (Intra-band) or non-contiguous in different spectrum bands (inter-band). This paper provides an overview of carrier aggregation along with some of the associated design and test challenges from the physical layer perspective for both evolved Node B (eNB) and user equipment (UE) followed by how to tackle those challenges using Agilent’s signal creation and analysis solutions.
· Using RF Recording Techniques to Resolve Interference Problems
As RF power is spread over wider bandwidths to improve range resolution, increase data rates, and decrease probability of detection, RF devices encounter a wider bandwidth of interference. As designers look to create robust solutions that can perform in such environments it becomes more important to create those conditions in the lab, or model those environments. This paper discusses the problems associated with system operation in a cluttered environment, and RF recording techniques that can be used to capture minutes or hours of data for subsequent analysis. The solution discussed in this paper is a dual channel PXI uW analyzer capable of 2 x 100MHz bandwidth simultaneous gapless recording capability to find an event that occurs infrequently. Having a dual channel system enables a number of interesting measurement modes that can be used to greatly reduce the effort involved in finding events of interest.
