Mitsubishi Electric Develops an Antenna using Seawater Plume

Mitsubishi Electric has developed an innovative antenna system, called SeaAerial, that shoots a column of seawater into the air to create a conductive plume for the transmission and reception of radio-frequency waves.

The system, which is thought to be the first seawater antenna, is capable of receiving digital terrestrial broadcasts for normal viewing. The company said it is investigating conductive and transmutative liquids as new materials for antennas.

RADWIN Launches Smart Beamforming Antenna

RADWIN introduced a point-to-multipoint antenna featuring a Smart Beamforming mechanism that can be used to deliver broadband access service with assured SLA over the unlicensed 5.x GHz bands in dense urban areas..  The company says its JET system cancels radio interference and enables operation in the most heavily congested unlicensed bands and in non-line-of-sight (NLOS)
conditions.

Some highlights:

  • Base station featuring Smart Beamforming antenna
  • Up to 250 Mbps per sector; 1 Gbps per site (4 sectors)
  • Multiband radio: 3.3-3.8 GHz or 5.1-5.8 GHz
  • Interference cancellation based on the narrow beam antenna
  • Guaranteed SLA per end-user
  • Small form factor, ruggedized IP67 units
  • Backward compatible with RADWIN 5000 installed base

Ventev Wireless Intros Optimized Wi-Fi Antennas

Ventev Wireless Infrastructure, a division of TESSCO Technologies, introduced a new line of TerraWave Solutions High-Density Antennas for Wi-Fi deployments in stadiums, convention centers, campuses, city centers, airports, manufacturing facilities, and other locales with high densities of wireless clients.

Ventev says its next-generation antennas increase capacity and optimize coverage for Wi-Fi users in large, indoor/outdoor venues by providing a narrower, focused beam of coverage that reduces channel-to-channel interference.

The highest-performing TerraWave High-Density 2.4/5 GHz Patch Antenna uses a narrow 35-degree beamwidth (compared with the traditional 50-80 degrees) and features a higher gain (14 dBi versus 6-10 dBi) that enables a greater distance between the antenna and users. Thus there is a much higher flexibility in placement without sacrificing network performance.

The 2.4/5 GHz 10/11 dBi narrow-bandwidth TerraWave Ceiling-Mount High-Density Antenna for indoor applications features an inconspicuous in-ceiling tile mount that camouflages the Wi-Fi access point for improved aesthetics and increased security. It is the only ceiling-mount high-density antenna currently available specifically designed for indoor applications such as convention centers, auditoriums, large warehouses and factories.

The new line of antennas supports all of the industry’s leading access points, including Aruba Networks, Cisco Systems, Juniper Networks, Meru Networks, and Motorola Solutions, among others. The antennas feature a broad range of technical specifications (gain, beamwidth, number of ports) and offer a variety of mounting options (ceiling, wall, mast/pole, under the seat) to ensure the right product is selected for the right application.

“Ventev’s TerraWave line of High-Density Antennas are being deployed in high-profile, high-density locations throughout North America,” said Jeff Lime, Vice President of Ventev Wireless Infrastructure. “As Wi-Fi continues to move beyond carpeted environments, including outdoors into stadiums and on campuses, the ability to provide stronger, reliable Wi-Fi signals to large numbers of simultaneous users – while mitigating interference – is a huge benefit.”
