NO-TIE TECH, LLC is a New Hampshire-based industrial wireless engineering firm headquartered in Lee, fully dedicated to cable-free control solutions, wireless retrofitting of legacy machinery, battery-powered wireless sensor networks, and short/long-range radio integration for manufacturers, agricultural operations, construction equipment suppliers and commercial facility operators across New England. Our coral brand color represents untethered connectivity, simplified field deployment, elimination of expensive wiring runs, and flexible industrial hardware that operates without fixed cable infrastructure. All wireless communication stacks, sensor node hardware, gateway configurations and control system retrofits engineered by No-Tie Tech follow FCC radio emission regulations, industrial low-power design standards, and best practices for robust wireless communication inside noisy factory environments. We deliver a complete cable-free service portfolio for industrial clients: wireless retrofit design for wired legacy equipment, Bluetooth and sub-GHz control link development, LoRaWAN long-range sensor network integration, battery-powered remote monitoring node design, wireless gateway setup and secure data forwarding, field radio range testing, enclosure design for outdoor wireless hardware, and ongoing support for wireless control system maintenance. Our wireless engineering design studio, radio test laboratory, prototype assembly workspace and administrative offices are located at 5 Radford Dr, Lee, NH 03861, positioned between Manchester and Dover with easy highway access serving clients throughout southeastern New Hampshire and coastal Maine. Our team consists of radio frequency engineers, embedded wireless developers, industrial retrofit specialists and field integration technicians equipped with spectrum analyzers, wireless range test equipment and low-power hardware prototyping tools. Our standard project workflow begins with site radio environment survey, evaluation of existing wired machinery, selection of suitable wireless communication technology, prototype node construction, on-site wireless signal validation, hardware installation, control logic integration and operator training. Cable-free wireless upgrades implemented by No-Tie Tech remove costly conduit and wiring labor, allow flexible relocation of machinery and sensors, and simplify expansion of production and monitoring systems.
Request Wireless Retrofit Site EvaluationNO-TIE TECH, LLC is a registered limited liability company operating from 5 Radford Dr, Lee, NH, US 03861. Founded by RF and embedded wireless engineers with over 24 combined years developing cable-free control and monitoring systems for industrial and commercial operators across the Northeast United States. No-Tie Tech was formed to address a consistent regional market gap: most automation firms focus on hardwired PLC architectures and ignore the challenges of retrofitting existing equipment with reliable industrial wireless links, leaving customers forced to install expensive new wiring or replace entire machine assemblies. All technical staff carry hands-on experience working with BLE, sub-GHz ISM band radios, LoRa transceivers, low-power microcontrollers, noise filtering for factory RF interference and battery power budgeting for multi-year unattended sensor nodes. Every new project starts with an on-site radio survey to map signal obstacles, metal obstructions and competing wireless signals. Inside our Lee radio lab we test communication reliability under simulated factory interference, optimize transmit power settings and validate battery life before deploying hardware into production environments. Our primary competitive advantage is exclusive specialization in cable-free industrial wireless retrofitting, dedicated RF test lab in Lee New Hampshire, deep experience converting legacy wired systems to wireless operation, and flexible project sizing suitable for small workshops and larger manufacturing campuses. Other regional tech businesses focus on broadcast AV, nanocoatings, field PLC service, remote telemetry or embedded PCB design without specialized knowledge of industrial radio propagation and wired-to-wireless machine conversion. No-Tie Tech unites wireless protocol selection, sensor node design, gateway integration, field RF testing and legacy equipment retrofit planning under one local New Hampshire facility. Our secure project archive stores all radio configuration files, range test reports and hardware documentation for future system expansion. From our Radford Road office our engineering staff can travel quickly to manufacturing and commercial sites throughout the Seacoast NH region for site surveys and commissioning. We provide three tiered service packages matched to project scale: Starter Retrofit Package – Short-range BLE or sub-GHz wireless link design for single machine sensor conversion; Standard Wireless Network Package – Multi-node LoRaWAN sensor deployment, gateway configuration and end-to-end data connection to existing control systems; Enterprise Facility Package – Full plant-wide wireless retrofit roadmap, interference mitigation design, long-term technical support and staged equipment conversion schedules to avoid extended production shutdowns. All wireless system configuration data and test records are securely hosted on United States servers.
Conversion of existing hardwired sensors, limit switches and control inputs to wireless communication links. Design interface circuitry to integrate radio modules with older PLC and machine controllers without requiring complete replacement of main equipment assemblies.
Short and medium range wireless communication system design for factory floors. Tuning transmit power, channel selection and antenna layout to resist RF interference from motors, variable frequency drives and other industrial electrical noise sources.
Deployment of low-power long-range sensor nodes for distributed monitoring. Gateway configuration, message routing setup, data buffering and secure forwarding of measurement data to local control systems or cloud monitoring platforms across wide facility areas.
Low-current embedded hardware engineering for unattended sensor nodes. Power management optimization, sleep-mode tuning and component selection to maximize runtime between battery changes for indoor and outdoor field monitoring applications.
Site spectrum analysis, identification of signal blockages and interfering equipment, real-world wireless range validation, antenna placement recommendations and written reports outlining achievable communication reliability across facility zones.
Configuration of multi-protocol wireless gateways to aggregate data from diverse radio nodes. Protocol translation to Modbus, MQTT or other formats compatible with existing PLC, SCADA and cloud monitoring infrastructure used by industrial clients.
Selection and modification of sealed enclosures for external wireless nodes, thermal design for New Hampshire seasonal temperature swings, antenna feedthrough layout and surge protection for hardware deployed in exposed outdoor locations.
Diagnosis of intermittent wireless communication dropouts, re-tuning radio parameters, relocation guidance for problematic nodes, firmware updates and engineering consultation for expanding cable-free monitoring and control networks over time.
Designed interface hardware to connect wireless radio modules to existing machine controllers, eliminating trailing cables on movable cutting carriages. Field testing confirmed stable communication under factory noise conditions and removed frequent cable damage failures experienced with the original wired setup.
Built low-power temperature and humidity wireless nodes, installed industrial gateways and integrated sensor data into facility climate control systems. No trenching or wiring installation was required, drastically lowering deployment cost across multiple separated greenhouse bays.
Installed battery operated wireless contact sensors on overhead warehouse doors, configured gateway data forwarding to facility management software. Avoided expensive wiring runs across large warehouse space and allowed flexible repositioning of sensors as loading zones are reconfigured.
