Wireless Design

Xekera Systems offers a broad range of experience in wireless design and implementation of Radio-Frequency (RF) Communications solutions. Our designs take into account the inherent trade-offs. Our previous RF projects have been focused on areas such as consumer portables, personal area networks, vehicle telematics, robotics, IoT gateways, towed-wave radar and microwaves, scientific testing equipment, ultrasound, and medical imaging systems (MRI). Our expert team always considers security when designing a product, especially one with wireless communications.

We have a team of engineers who can help you develop RF solutions for a wide range of project needs and specifications.

Quality Management Systems

At Xekera, we follow the Quality Management System defined by ISO 9001. We always start off a project with a detailed project specification with achievable milestones and the costs involved. Once the client approves this, we treat it as the master plan. We demonstrate our commitment by working towards the project specifications.

For our requirements from the client for designing a product, please send an enquiry or give us a call.
