Russia Requires WiFi Registration
While WiFi wasn’t as broadly unlicensed in Russia as it is in most other industrialized nations, your can not find wifi antenna anywhere a state regulator exempted indoor use in certain bands from registration. The Mass Media agency apparently believes that it has the authority to compel this, although there’s some doubt by observers as to whether it really falls in their purview.

MR330T



Description


GPS receiver and antenna in a fully weather proof enclosure for time transfer application

The AQTIME MR-330T is the integration of a timing GPS receiver and antenna in a compact/weather proof enclosure for time transfer application. It outputs UTC synchronized 1PPS with +/- 1 microseconds tolerance, which is close to an atomic clock in accuracy. As a time transfer device, the AQTIME MR-330T is capable of operating with even 3(three) satellites after having a fix position with 3 or more satellites previously, so you can get precise time base anywhere on the Earth even under a very harsh environment where only one satellite is available.

Key Features:

  • UTC synchronized precise time base can be obtain anywhere on the earth at a relatively low cost
  • Ultra compact, fully weather-proof, easy to mount
  • Quick start, 18 seconds warm start typical
  • Continue to output time data with even one satellite tracked
  • Wide supply voltages range (9~34VDC)
  • Low power consumption (0.9W typical)

Applications:

  • Time Stamp Data Logger
  • Synchronization of radio base stations for cellular
  • Phone, pagers,¡Ketc. Time control of computer terminals connected to network
