Investigating Electromagnetic Compatibility (EMC) Failures in RF Devices
EMC measures how well a device works in its electromagnetic environment. The device must function correctly without creating problems for other nearby equipment.
Forensic Analysis of SIM Card and Baseband Communication in Mobile Devices
Mobile devices provide key evidence in investigations. The SIM card and baseband processor store communication and location data.
Cold Weather Failures in Mobile Phones: Engineering Analysis in Product Claims
Mobile phones must work reliably in cold environments. This includes rural areas, vehicle breakdowns, and emergency responses.
USB-C, Lightning, and Other Interfaces: Product Liability and Warranty Disputes in Mobile Devices
Mobile device connectors serve two roles. They function as electrical components. They also create legal exposure points.
RF Exposure Claims and Cellular Sites: What Engineering Says vs. What the Public Fears
Public concern grows when cell towers appear near homes or schools. Engineers measure exposure with physical laws and field strength. They compare results against safety limits. They do not rely on assumptions or stories.
The Role of Passive Intermodulation (PIM) in Wireless System Failures
When two or more radio signals interact within passive components, they can generate unintended new frequencies. This phenomenon is known as Passive Intermodulation, or PIM.
RF Interference Investigations: From Garage Door Openers to Military Radar
Radio Frequency Interference disrupts signal transmission. Unwanted electromagnetic energy blocks equipment from working properly. Both natural and man-made sources create this problem.
Equipment Room Failures: How Poor Grounding and EMI Shielding Cause Downtime
Equipment rooms need reliability. Small errors create hidden risks. Poor grounding and weak EMI shielding trigger random shutdowns.
How Antenna Misalignment Affects Coverage and Legal Exposure
Antenna alignment means positioning a cellular antenna so its radiation pattern matches the intended design.
