Trimble SNB900 Radio License-free, high-speed data link for the construction jobsite Imagine a radio link for GPS that does not require licensing and is virtually immune to jamming and interference. Trimble introduces the 900MHz product family, featuring the Trimble® SNB900, SNR900 and TNR900. The SNB900 radio is ideal for permanent or mobile base stations and repeaters. You can use the versatile SNB900 for a rover in a supervisor’s truck or on a range pole. The 900MHz frequency offers many advantages for the construction site:
- Virtually immune to interference
- No licensing is required
- Low-latency, high-speed link allows two-way data between office and site machines
- Good operating ranges for construction sites. For areas in radio shadow, such as valleys, now it’s easy to place a SNB900 as a repeater.
- The internal battery provides added daily productivity, as setup is faster and easier.
Convenient Portability The SNB900 is so lightweight and portable, it fits in your jacket pocket to carry onto the jobsite. The built-in screen and keyboard make onsite setup and status checking even more convenient–you don’t need an external PC or data collector when in the field. You can set up operating modes, network configurations, port and display configurations, and check on battery status, radio status, operating mode, and network number. Then simply call the site office staff to check the status onscreen instead of driving there. External Antenna The SNB900 features an external antenna that easily mounts on a single tripod with the GPS base antenna. The external antenna also lets you locate the SNB900 in a locked, secure position with only the antenna outside. Unlike systems with the radio antenna integrated into the top of the GPS antenna. Now it’s easy to place the antenna higher to achieve the greater range needed for base station applications. The external antenna also allows for any necessary lighting protection to be added. Easy Setup You can quickly set up a repeater—just find a suitable location, place the SNB900, and turn it on. Because the SNB900 operates on internal batteries, it will run all day with no external power source. As many as four SNB900 repeaters, are supported from a single base station, with the ability to have three in a row. Since no setup software and PC/data collector are required to set up a repeater function, the reception statistics on the display make it easy to select an optimal location. Internal battery The SNB900 operates all day with no external battery for fast set up as a repeater or base. Rover operation is simple since the no cables are required. Because the SNB900 internal battery has its own internal battery charger, when it’s connected to the site power supply, it is continually charged. If the site loses power, the radio will continue to operate uninterrupted for up to 10 hours. Dual data links When you need dual data links on site, it is easy to connect an additional narrowband radio such as the Trimble® TRIMMARK3™ to the SNB900. This is possible as correction data can be passed through the SNB900 to a second radio. Two-way IP data capable Connect the SNB900 to the TNR900 to create an IP access point onsite. The SNB900 access point does not have to be at the base station; it can be a repeater site—wherever the Internet connection is available onsite. Features:
