The DVK-BL652-SC is part of the range of RF evaluation and development kits, boards, and modules available to engineers and professionals for their applications. This device is a Small Cell/LTE protocol emulator and channel emulator which allows users to test or develop systems that require the exchange of complex communication information. Specifically, it allows users to develop prototypes and small cells for Long Term Evolution (LTE) and Wireless Broadband (W-CDMA).

The DVK-BL652-SC consists of two main modules. The first is the Protocol Emulator (PE), which is responsible for communicating with the rest of the system. It transmits and receives LTE and W-CDMA protocol-level information, such as the LINK PDUs, STATUS PDUs, and frame numbers. The second module is the Channel Emulator (CE). The CE is responsible for simulating radio frequency (RF) environment parameters, such as SNR, Co-channel interference, and uplink/downlink channel impulse responses.

The DVK-BL652-SC is a versatile device that is suitable for a number of applications in both commercial and industrial settings. Among the most common applications are as follows:

• Testing base station and terminal products for RF measurement and simulation.
• Testing for compliance with 3GPP (3rd Generation Partnership Project) standard protocol requirements.
• Small-cell (indoor base station) development and deployment.
• Radio access network troubleshooting and optimization.
• In-building and short-range hotspot development and deployment.

The working principle of the DVK-BL652-SC is based on a two-step process. First, the Protocol Emulator handles the protocol operations, transmitting and receiving the protocol-level information. Second, the Channel Emulator simulates the RF environment parameters, such as SNR, co-channel interference, and uplink/downlink channel impulse responses. This allows for in-depth testing and development of systems that require the exchange of complex communication information.

The device is easy to use and requires no particular expertise in the field of RF technology. The device can be equipped with multiple antennas, such as directional antenna systems, to better measure and simulate the RF environment. Additionally, various measurement instruments, such as spectrum analyzers, oscilloscopes, and signal generators, can be used to perform additional tests and measure the results.

The DVK-BL652-SC is a powerful tool for engineers and professionals who require a device that combines a protocol emulator and a channel emulator in a single easy-to-use module. With its wide range of applications, it can be used to develop, optimize, and test different wireless communication systems.
