promwad Telecom


Telecom Software Solutions

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.

How we work

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.

We work with

Startups & SMB

We work with start-ups, small and medium-sized companies to help them develop new software and hardware solutions based on the latest networking technologies for their business.


We design new devices and programmes for international tech leaders worldwide. They deliver these new products to end users or service providers (cloud, internet, satellite, wireless, cellular/mobile services).

Tech Partners

We collaborate with global tech vendors and distributors, OEM and manufacturing sites, and other design houses to complement each other's expertise and achieve our business goals together.

Telecom equipment engineering

LAN / WAN / WiFi routers

Our clients stay one step ahead of trends in the telecom market with the next-gen LAN / WAN / WiFi routers and other access point devices. Experienced since 2004, our team focuses on advanced telecom and rugged applications with high-speed interfaces, multi-layer PCB, proper thermal and signal integrity modelling.

Network switches

We design Ethernet switching equipment which serves as an integral part of any intelligent network. Our telecom R&D unit has hands-on experience with network switch technology and switch SDK from leading chip vendors. Among the examples of Ethernet switching devices are:

  • stackable & managed access switches
  • carrier Ethernet switches/routers/gateways
  • security appliances
  • aggregation switches & routers
  • TSN Ethernet switch solutions

Telecom 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
Remote desktop software integration: implementation of RDP, Citrix ICA, and VMwareP CoIP protocols
Development and upgrade of Linux-based software for L2 switching and L3 forwarding with VLANs, flow control (802.3x), etc.
Design of user interfaces and applications for managing network devices and infrastructures via web GUI, CLI, SNMP, etc.
Development of VoIP solutions, including SIP user agents with hardware-accelerated audio/voice processing
Optimization of the network stack for a hardware platform

Customized telecom solutions


VoIP integration, and more

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. 

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. 

q-in-q microchip

Selective Q-in-Q

SDK: Microchip IStaX-APPL-2020.09.

Tested on a PCB135 debug board from Microchip on VSC7558. Q-in-Q operates on the Sparx-5 microprocessor family.

Description: Selective Q-in-Q determines the pairing of a given client VLAN (on the UNI side) and the sought S-VLAN identifier. The S-VLAN identifier is joined to the input unmodified C-VLAN, and the packet is forwarded across the ISP's double-tagged network. The S-VLAN ID is removed from the output, and the client VLAN ID is retained in the packet. Packets that do not match the specified client VLANs are discarded by default.
