Telecom
Design and manufacturing of telecom equipment
Since 2004, Promwad has been helping customers to be on the cutting edge of telecommunication technologies, creating for them new networking devices and software within long-term R&D co-operation models.
We work with manufacturers of telecom equipment, integrators, and telecom operators to create commercially successful network solutions for faster and more accessible broadband Internet for end-users and businesses.
Our clients are companies with many years of experience in telecom, they do not just follow trends of the industry, but also set them through constant innovations and R&D process. To be in the avant-garde, to offer eco-friendly and convenient network devices – not only in terms of technology but also in terms of design – these are the goals set by our customers.
Many of our clients have their own R&D departments and experience with Chinese manufacturers. However, they choose Promwad to take their business to the next level, as they trust our experience in telecom electronics design and partnership with world-leading semiconductor vendors.
Networking hardware and equipment
We design bespoke hardware and network appliances for high-speed data processing:
- End-user equipment: CPE, routers, residential gateways, set-top boxes, home networking adapters, wireless AP, and thin clients.
- Ethernet switching: stackable and managed access switches, Сarrier Ethernet switches/routers/gateways, security appliances, aggregation switches and routers.
- Industrial network equipment and industrial Internet of Things (IoT): switches for industrial process control, transportation and automotive applications, smart grid energy distribution.
- Custom FPGA network cards for broadcast video, high-performance computing, AI, and data-center applications.
Our developments meet high requirements for data network bandwidth capacity.
I want to mention the high level of proficiency of Promwad. They developed excellent technical solutions in full compliance with the specifications. Transparency of company processes made a very favourable impression.

Software development
We develop software for network equipment in compliance with the highest requirements for bandwidth and quality of service (QoS) performing the following tasks:
- Development of system drivers for network chips, wire and wireless interfaces
- Optimization of the network stack for a hardware platform
- Development and upgrade of Linux-based software for L2 switching and L3 forwarding with VLANs, flow control (802.3x), flow/port mirroring, IGMP snooping, GVRP, etc.
- Design of user interfaces and applications for managing network devices and infrastructures via web GUI, command line interface (CLI), simple network management protocol (SNMP), telnet server, JSON RPC, etc.
- Development of VoIP solutions, including SIP user agents with hardware-accelerated audio/voice processing
- Remote desktop software integration: implementation of RDP, Citrix ICA, and VMwareP CoIP protocols
Promwad software engineers have developed system and user software for managed switches with Energy Efficient Ethernet and PoE support, home and industrial routers, hubs, and other network devices.
Our portfolio includes specialized distribution files for VoIP devices, embedded solutions for thin clients and mini-servers. We also developed a full software package for the second commercial plug computer in the world.
