DL475-70 maintains distortion free signal at higher modulation rates and high power to maintain low packet errors and maximize data throughput. The design uses highly linear power amplifier to deliver maximum power even at 64 QAM radio modulations while maintaining low distortion EVM (Error Vector Magnitude). With better Rx sensitivity and high SNR, DL475-70 is specially designed to deliver best performance in long-range applications. The Industrial/Military grade design & enhanced resilience to RF surges & ESD makes it ideal for deploying in harsh environments.
Key Features
- Best-in-class OFDM broadband radio technology ensures high throughput, spectral efficiency, advanced RF interference mitigation and resistance to multi-path delays for Near Line of Sight (NrLOS) performance.
- Doodle Labs’ proprietary PrismTM hybrid heterodyne technology with advanced filtering and noise reduction techniques to achieve high Interference Immunity.
- Operation in the 440 - 510 MHz UHF frequency band for radio services in the ITU’s regions 1, 2 and 3.
- Up to 48 Mbps data throughput.
- Software configurable high Tx power up to +31 dBm (1.3 W) for long-range coverage.
- High desensitization capability for out of band interfering signals.
- Distortion free signal (low EVM) to maintain lowest packet errors to maximize data throughput at higher data modulation.
- 128 bit AES encryption for over the air data security
- Supports software configurable 5/10/20 and 40 MHz Channel Bandwidth to maximize spectrum efficiency.
- Traffic prioritization queues for video, voice and data applications.
- mini-PCI host interface
- Supported by open source MadWiFi Linux kernel drivers
- Proven compatibility with dd-wrt and many other 3rd party Wireless Router Operating Systems
- Military grade design ensures durability in harsh operating environments
- Two MMCX connectors provide flexibility in system design for antenna diversity or Internal/external antenna selection options
