Beamforming antennas for hazardous areas

The recent improvements in beamforming and internal antennas makes them the ideal choice for most applications, including hazardous areas and industrial settings.

When we designed the Wireless X we wanted to be able to encapsulate the most flexible and latest technology from leading vendors. The reason being the better the technology, the more speed and security we can offer, also with better coverage and increased speede fewer access points is needed. Also being able to standardize on a single model or type across both non-ex and ex areas is a benefit for most clients, simplifying the design and rollout.

Beamforming concentrates the signals exchanged between a Wi-Fi router and the clients it’s paired with.

802.11ac is becoming the standard for most enterprise clients. New versions of the standard is in the making and choosing an access point which is future proof and capable of the latest and greatest speed and coverage is important when deploying enterprise wide wireless networks.  With innovations like CleanAir, ClientLink 2.0 and VideoStream, Cisco has made great progress in boosting speed and coverage for their latest access points with internal antennas. The  industry has been an ever-changing and increasing need for speed, which makes it a little strenuous for some network providers of yesterday to change its current system.


Since mobility products and services become a vital requirement for the consumer, cases of security standard and technical mismatch emerge. For this purpose, Cisco has made a change to its past product line of access points. Some of these Access Points include Aironet® 1040, 1140, 1260, and 3500 Series which are replaced with the product lines Aironet 1815, 1830, 1850, 2800, 3800 series. These product lines come with the new generation 802.11ac access points. With these new product lines, there is an improvement in spectrum intelligence, internal antenna, antenna density, and client acceleration. This means fewer access points need to be installed, and the latest and greatest security is in place. The new generation of Cisco’s Aironet access point is tailored to a wide variety of requirements for the state-of-the-art, demanding, and business service to pave room for dependable wireless communications. Cisco’s range of access points can meet the client’s connectivity demands irrespective of what the requirements are, be it a small wireless network for home and small business, or network for high demanding signal coverage for different locations.

The new Cisco access points with internal antennas come with an in-built 801.11ac Wave 1 radio and compatible with 4×4 MIMO standards with spatial streams features. These access points performance is three better than the present day 802.11n Wi-Fi on both short and long-distance communication. Also Cisco has made lots of improvements in access points roaming in terms of speed of attaching and release of clients. Not only the improved antenna, the new access points are more energy conservative. Also, the latest internal antenna access points have lower noise compared cross access points. Also thee models are improved with precise location. The 80-GHz channel support on Cisco’s CleanAir® offers better location tracking.

These internal antennas are perfect for both office and industrial installations. With Cisco’s CleanAirTM innovative technology which enables autonomous repairing and self-enhancing network Pperformance enhancements for mobile devices such as phones, PCs, tablets, and any other devices utilizing 802.11ac one spatial streams, two partial streams, or three spatial streams, with Cisco’s ClientLink 2.0. Extended support also goes to 802.11a/g devices as well.

Access points having built-in antennas have an “I” in its nomenclature for example 3800i. There is a relatively low gain for external antenna arrays (2.4 GHz, 2 dBi, and 5GHz, 4 dBi). While the internal antenna has a relatively high gain(2.4 GHz, 2 dBi, and 5GHz, 4 dBi) they are also factory configured in the right way and are slightly less expensive.

To conclude we recommend the access points with internal antennas mounted in the Wireless X since it offers the latest technology, combined with compact form factor. Also, since we don’t rely on external antennas the cost and weight is favourable compared with legacy solutions.
