ROUTER, VOIP and Smart Home Functionalities IN One Device
Case study
About Client
PingCommunication – a Nordic technology company specialized in designing and manufacturing Access Devices like xDSL, Fiber, Cable, Ethernet, 3G/CDMA Gateways, Mesh systems, and a wide variety of Home Networking Products. In 2021 the company merged with 2 Scandinavian companies to became Heimgard Technologies.
The client needed a cross-functional team of Embedded Software Engineers and Front-end Developers to deliver the product for – fully functional router for market release.
Our Services
We built and provided a cross-functional team of Embedded Software Engineers and Front-end Developers who worked with the Client from 2018-2021. In total, 14 engineers were engaged in the project.
The team’s first task was integration and modification of SDK from HW provider (Realtek) and then product development related to the following areas:
· Low-level Linux – handling memory, drivers, configuration
· VoIP– implementation of most VoIP gateway functionalities. FXS and DECT integration, adding an abstraction layer separating the FXS/DECT device type from higher layers, modifying the behavior of the SIP application to meet customer requirements
· router configuration (VoIP, networking, smart home) – responsibility for the back-end and front-end (WebUI)
· Router core functionalities: WAN/LAN configuration, software update, security, etc.
· Running Wi-Fi tests
CHALLENGE
The main challenges in the project:
· meeting all required product functionalities for the end user while taking into account hardware limitations
· modification of FXS support and implementation of DECT support from scratch (integration of CMBS API from DSPG and its support)
· creation of an abstraction layer for FXS / DECT and implementation of call control features in phone (VoIP application integrated in Realtek SDK)
· modification and implementation of new functionalities in the back-end.
SOLUTIOn
Innovative and multi-functional device – a premium router with the functionalities of an ordinary router, a VoIP gateway and Smart Home.
Our Team was responsible for implementing and integrating various functionalities related to different areas and delivering a fully functional router.
