We design networks and wireless communication systems, ensuring stable data transmission, reliable coverage and scalable solutions for the tasks of a specific facility.
We design wireless communication networks for industrial, commercial and infrastructure facilities. We develop a project for wireless communication networks, including equipment placement diagrams, calculation of coverage areas and data transmission channels. Well-designed networks and wireless communication systems ensure stable operation, secure data transmission and readiness for network expansion.
Why is a wireless network designed “from experience” always inferior to a calculated one?
The wireless data transmission medium is the most unpredictable in an engineering sense: the radio wave is not visible, its behavior in a particular building depends on the material of the floors, the placement of shelving, the number of simultaneously operating devices and neighboring networks. That is why “designing for the number of users” without radio surveys and predictive modeling invariably leads to the same result: dead zones in 30% of premises, overloaded access points in crowded areas and chronic switching of subscriber devices between channels with loss of sessions. Redesigning an installed wireless infrastructure costs two to three times more than the original correct design.
AYU-Project designs wireless data networks and professional radio systems for industrial enterprises, office and retail facilities, transport and energy infrastructure. We develop design documentation and working documentation based on predictive modeling and full-scale radio survey - so that each access point, base station or subscriber device operates with design characteristics under the conditions of a specific facility.
What types of wireless networks do we design?
AYU-Project covers the entire range of wireless data transmission technologies in demand at commercial and industrial facilities:
Wireless Local Area Network (WLAN/Wi-Fi)
Corporate and technological networks of Wi-Fi standards IEEE 802.11ac (Wi-Fi 5), 802.11ax (Wi-Fi 6/6E) and 802.11be (Wi-Fi 7) for offices, warehouses, production workshops, sales areas, medical institutions and open areas. We design managed systems with a controller (WLC) or controllerless solutions based on cloud management; We provide traffic segmentation, roaming and integration with the RADIUS server for authentication 802.1X.
UKV-radio communications and professional mobile radio (PMR)
Operational voice and digital communication systems for facility personnel: technologies DMR (Digital Mobile Radio, ETSI TS 102 361), TETRA (Terrestrial Trunked Radio) and analog ChM systems. They are used at industrial enterprises, energy facilities, transport infrastructure and facilities with security services. We design from single repeaters to multi-zone trunking systems with full coverage of the territory.
Wireless Broadband (WiMAX/BWSA)
Fixed and mobile wireless broadband access networks for connecting remote sites and corporate sites to backbone channels in the absence of cable infrastructure.
Satellite communications (VSAT)
Organization of data transmission channels for objects located outside the coverage area of ground infrastructure: oil fields, rotational camps, remote industrial sites. We design VSAT stations based on satellites GEO (geostationary) and LEO (Starlink low-orbit systems, OneWeb): the choice is determined by latency and throughput requirements.
Radio relay lines (RRL)
Design of radio relay spans for inter-facility communication (for more details, see the “Warning and Radio Communication Systems” section of our website).
Site Radio Survey as the Basis for WLAN Design
A radio survey is a field measurement of the real radio frequency situation at a facility, without which a correct Wi-Fi network design is impossible. It identifies existing sources of interference (neighboring networks, industrial equipment, medical devices), determines actual losses in building structures and verifies the parameters of the predictive model.
Passive radio survey - scanning the air without deploying test access points: SSID, channels, signal levels and noise floor (noise floor) of all visible networks in the 2,4 GHz, 5 GHz and 6 GHz bands are recorded. The result is a heatmap of interference with identification of occupied channels and assessment of the interference level.
Active radio survey (AP-on-a-stick) - deployment of a temporary reference access point sequentially in several positions with measurement of RSSI, SNR and throughput along the intended user routes. This allows you to verify the predictive model and adjust the location of access points before installation.
For production facilities and warehouses with heavy traffic of AGVs and material handling equipment, it is necessary to conduct an inspection under conditions of simulating workload: it is during the movement of metal-intensive equipment that dynamic signal blocking occurs, which is not visible on the static model.
Predictive Modeling: How do we calculate Wi-Fi coverage?
Predictive modeling is the calculation of the coverage area in a specialized software based on a digital model of the building indicating the types and thicknesses of partitions, ceilings and specific obstacles. This is a mandatory step when designing WLAN for facilities larger than 500 m², as well as for any multi-storey and industrial facilities.
The process includes the following steps:
- Import of architectural plans - floor plans with scale indication are loaded into software (Ekahau, Hamina or analogues), walls, partitions and ceilings are traced and attenuation parameters (dB) are assigned to them in accordance with the material;
- Assigning access point parameters - AP models, antenna patterns, power, ranges and standards;
- Coverage calculation - the program calculates RSSI and SNR at each point of the plan; zones with a signal level below the threshold are identified (usually RSSI ≥ −70 dBm for data transmission, SNR ≥ 25 dB for 5 GHz);
- Frequency planning - distribution of non-overlapping channels among access points to minimize mutual interference; for 2,4 GHz - channels 1, 6, 11 (three non-overlapping); for 5 GHz and 6 GHz - a significantly larger number of non-overlapping channels;
- Bandwidth calculation - assessment of the maximum number of simultaneously active client devices per access point, taking into account bandwidth requirements per client.
Features of Wi-Fi design for industrial facilities
Industrial Wi-Fi networks require a fundamentally different approach than office ones. A production workshop or warehouse is not an open space office: metal racks and stocks create shielding zones, metal dust affects the RF environment, variable frequency drives and welding equipment generate interference in the 2,4 GHz range. For such objects, the priority range is 5 GHz or 6 GHz; shielded or directional antennas; application of the standard IEEE 802.11r (fast BSS transition) to ensure seamless roaming of WMS mobile terminals without session interruption.
For Wi-Fi technology networks (wireless SCADA terminals, PLC with Wi-Fi modules), compatibility with industrial protocols (EtherNet/IP, PROFINET over Wi-Fi) is additionally analyzed and traffic prioritization ASU transformer substation with QoS marking is provided.
Professional DMR and TETRA radio communications for sites
Professional mobile radio (PMR) is an essential part of the technological infrastructure of industrial enterprises, large construction sites and sites with security services: it ensures prompt communication of personnel where cellular networks are overloaded or unreliable.
DMR (Digital Mobile Radio, ETSI TS 102 361) - digital standard for corporate radio networks Tier II (direct link and repeater) and Tier III (trunking): high energy, range up to 40 km from the base station, cost lower than TETRA. It is used on industrial sites, in housing and communal services, logistics and security structures.
TETRA (Terrestrial Trunked Radio) - standard for critical facilities: electric power facilities, transport infrastructure, oil and gas industry facilities. Provides encryption of conversations, group calls, emergency call prioritization and data transfer (SDS, packet mode). Cell size - up to 20 km; when continuous coverage is required on extended objects (tunnels, pipelines), technology is used Distributed Antenna System (DAS) with fiber optic feeder.
Design of a PMR system includes calculation of the number and placement of base stations, coverage areas, signal levels (link budget), communication organization scheme, equipment composition and materials for obtaining permission to use radio frequencies in Roskomnadzor.

Frequently Asked Questions
For BLVS: architectural floor plans (PDF/DWG) indicating partition types; estimated number of users and devices by zone; requirements for traffic segmentation and authentication. For PMR: area and configuration of the territory, presence of tunnels or extended facilities; number of subscriber devices; encryption requirements. We will clarify the missing data during a free initial consultation.
If a wireless network was built without a design, this means there was no documented frequency plan, VLAN segmentation scheme, or calculation of coverage areas. When expanding a facility or replacing equipment, an engineer work without input data - any configuration change creates unpredictable interference zones. In addition, for capital construction projects, the wireless networks section is part of the PD according to Russian Government Resolution No. 87. We also carry out retro-design - development of documentation for existing infrastructure.
For a facility with an area of up to 5 000 m² - 2-3 DD weeks and 3-4 WD weeks. For large multi-level or industrial facilities with several technological zones - individually. For PMR systems (DMR/TETRA) with a frequency coordination procedure, the deadlines are increased for the duration of regulatory procedures at Roskomnadzor. All terms are fixed in the contract.
In the absence of a finished building, predictive modeling is performed using architectural plans - this is standard practice. In this case, radio inspection is transferred to the commissioning stage (validation inspection). The project includes an iterative mechanism: based on the validation results, it is possible to adjust the location of several access points without reworking the entire infrastructure.
No. For B2B facilities this is a fundamental requirement. Consumer-grade (SOHO) access points do not provide centralised management and monitoring, 802.1X enterprise authentication, QoS traffic prioritisation, seamless 802.11r/k/v roaming or industrial-grade construction. They are not designed to serve more than 10-15 active clients simultaneously. A design based on consumer access points cannot guarantee the performance specified in the design documentation.
Seamless roaming allows a client device, such as a WMS terminal, barcode scanner or mobile computer, to switch between access points without interrupting its session. Under IEEE 802.11r, handover takes less than 50 ms, preventing WMS database transactions from being interrupted. Without seamless roaming, forklift movement between access-point coverage zones can interrupt transactions and lose inventory movement data.
Access points operating in the 2,4 GHz range (up to 100 mW EIRP) and 5 GHz (up to 100 mW EIRP in bands allowed for use without frequency assignment) do not require a permit to use frequencies. The 6 GHz band (Wi-Fi 6E) in Russia is in the process of regulatory approval; for PMR systems (DMR, TETRA), permission to use frequencies and registration of radio electronic devices with Roskomnadzor are required.
Wi-Fi 6 (IEEE 802.11ax) differs fundamentally from Wi-Fi 5 (802.11ac) through OFDMA technology: instead of serving clients sequentially, an access point can transmit data to several devices simultaneously within one channel, which is critical in high-density environments. For conference rooms, retail floors, production areas with WMS terminals, healthcare facilities and any scenario with more than 20-30 devices per access point, Wi-Fi 6 is essential. There is little reason to specify Wi-Fi 5 for a new facility: the equipment cost difference is minimal, while the available capacity for the next 5-7 years is substantial.
