Final answer:
Real-time testing is made difficult by limited device processing capacity, power limitations on the device, and unique mobile network infrastructures.
Step-by-step explanation:
The issues that make real-time testing difficult include:
- Limited device processing capacity: Real-time testing requires devices to process and handle data quickly and efficiently. If a device has limited processing capacity, it may not be able to handle real-time testing effectively.
- Power limitations on the device: Real-time testing often requires continuous power supply, especially for devices that are constantly transmitting and receiving data. If a device has power limitations, it may not be able to sustain real-time testing for extended periods.
- Unique mobile network infrastructures: Real-time testing relies on mobile networks for data transmission. Different regions and countries may have unique mobile network infrastructures, which can create challenges for real-time testing across different locations.
