Designed for communication band
signal jamming, the QBS-617 can be used in various public safety applications, for risk mitigation of remote controlled explosions, and to prevent cellular services in and around secure military and government facilities.
This, NEC argues, enables enhancement of security and certification, as well as control management of communication band
and usage amount.
4 GHz band of a WLAN system is also available and it is possible that the tablet terminal automatically selects the radio communication band
according to data traffic, etc.
The low-cost CX6002 filter module allows two-way communication between the customer premise equipment (CPE) and the cable network with minimal crossover interference between the downstream broadcast frequency spectrum and the customer-to-Internet upstream communication band
A wide range of state-of-the-art horn-based and splash plate feed systems are available for prime focus and single and dual-offset antennas covering all the key satellite communication bands
, including C, SHF, Ku, DBS and Ka-band frequencies.
Networking products using these communication bands
have higher data throughput than for those in lower frequency bands and can be used in all geographic regions.
Airfast RF power solutions are expected to deliver the industry's widest bandwidth products, and are intended to support signals in excess of 150 MHz instantaneous bandwidth and enable simultaneous operation over multiple communication bands
Flexible Coverage and Frequency Support C Operates on the 800/1900MHz mobile communication bands
, ensuring complete coverage
A cooperation agreement has been inked between Iran and Russia on utilization of the very high frequency (VHF) and ultra high frequency (UHF) wavelengths communication bands
UHF RFID communication bands
are specified for use between 860 MHz and 960 MHz by international standards.
Professor Gert Frolund Pedersen, Head of the Antenna and Propagation section at Aalborg University, articulates the issues being addressed by the SAFE consortium, "Since the mid-1990s, we have struggled to get more bandwidth out of cheap antennas that cover a wide range of mobile communication bands
According to the company, CoDeSS make use of spot jamming, barrage jamming and sweep jamming together with other tactics tailored to threat types within the HF and UHF communication bands
