RF & WIRELESS DESIGN

Etrotrust Technologies has wide-ranging expertise with wireless design and implementing Radio-Frequency (RF) Communications solutions. We understand the trade-offs inherent in these designs. You can reach us for your RF system projects such as consumer portables, personal area networks, vehicle telematics, robotics, IoT gateways, radar and microwave applications, Time-of-Flight ranging, scientific test equipment, ultrasound and medical imaging systems (MRI). Product developers should always consider device security, especially when wireless communications are included in the design.

WIRELESS DESIGN EXPERTISE

RF Design

rf circuit board
  • Frequencies up to ~50 GHz
  • Utilizing RF “building block” ICs:
    • Transceivers, mixers, PLLs, LNAs, PAs
    • RF microcontrollers (SoC) – Nordic, TI, Dialog Semiconductor, NXP, etc.
  • Wi-Fi, GPS and cellular (GSM/GPRS/ HSPA/CDMA) integration
  • Low power ultra-wideband (UWB) and Doppler radar
  • RFID, NFC
  • Microwave (terrestrial and space)
  • Machine-to-machine (M2M) communication
  • Circuit simulation, impedance matching, and network tuning
  • Industrial, scientific and medical (ISM) radio bands
  • Feasibility assessment by modeling radio system signal propagation based on:
    • Range
    • Terrain
    • Carrier frequency
    • Power
  • Collision detection
  • Application specific communication protocols
  • Frequency hopping spread spectrum (FHSS)
  • Listen Before Talk (LBT)
  • Instrument, analyze, identify and solve bandwidth saturation problems

RF Communication Protocols

  • ZigBee, IEEE 802.15.4 low-rate wireless personal area network (LR-WPAN)
  • GSM, GPRS, HSPA, CDMA
  • IEEE 802.11a/b/g/n
  • NFC, Bluetooth Low Energy (BLE), Bluetooth wireless technology, IEEE 802.15.1
  • WiMAX
  • Software Stacks
    • TI SimpliciTI and SimpleLink
    • lwIP (TCP/IP)
    • Bluetooth GAP and GATT

Wireless Applications

  • Over-the-Air (OTA) firmware update solutions
  • Pairing and device bonding
  • Security – standards based or “purpose-built”
  • Error detection and recovery

Radio systems

  • Mesh, master and slave networks
  • Portable battery-powered devices
  • Customized network protocols
