Network Equipment Solutions
For nearly two decades, we create innovative and cost-effective multi-purpose network equipment for our clients.
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 designed by Promwad.Â
What we do
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. We design for our clients:
- Network routers
- Low-power mini servers, thin clients
- Analog-to-digital PBX & VoIP routers
- Network-attached storages (NAS)
- Equipment for wireless access points (WLAN)
- Baseboard management controllers (BMC)
- Multi-purpose network devices for smart home and office, digital TV, telephony, Internet, etc.
- Custom CWMP client applications (TR-069)











How we create business value: some of our case-studies

7-in-1 modem router
We have designed and prepared for mass production an advanced VoIP modem router that provides all types of office communications (7 devices in 1).
Our engineers designed an enclosure, hardware, low-level software, and Linux-based middleware, as well as stands for functional testing at the production site. The new product included the functionality of seven devices in one:
- telephony with DECT base station,Asterisk-based VoIP gateway, and office PBX;
- Internet and local network via Ethernet, xDSL, WiFi, 3G, WiMax;
- connection with peripheral devices and operation of network storage (NAS).

Mobile router with LTE/3G/GSM
Commissioned by our client, we designed a router for stable internet access with the simultaneous operation of three SIM cards from different operators: up to 300 Mbit/s. Features:
- 2G/3G/LTE modem with 3 SIM cards connected via Ethernet or Wi-Fi
- Freescale i.MX6Solo/6DualLite CPU, ARM Cortex-A9
- Internal battery + external power source
