With the speed of our Wireless emerging markets growing faster plus the demands of Lighting fast data rates in GigE capacity to keep up with Productivity , many IT Professional are looking at what other companies have invested their infrastructure to create immediate Mission critical solutions for either Rapid deployments needs or Disaster Recovery planning as Fail overs.
And now they are having 2nd look & turning to Fiber Wireless radios to fulfill their needs & perhaps not so much Fiber trenching which can be time consuming with permits to wait on & delays of just wanting to move into new locations to consider.
Alternative choices at hand - we see them based on Field tested results & 100% Customer satisfaction with many of our clients ( USA & International ) who have taken their 1st steps and experienced immediate business gratification in form of Revenue increase due to Productivity & Cost savings in their bank books.
These 3 main true tested Technologies are - Last Mile solutions in Optical communications ( FSO ) , eBand links 70/80Ghz mmWave radios & traditional microwaves for short / long range connectivity. When you get a chance look into them & see which may fit your next IT rollout LAN / WAN broadband wireless project.
Millimeter waves are radio waves with a frequency between 30GHz to 300GHz. Millimeter wave radio offers several advantages and a few disadvantages over lower frequency microwave communications.
The primary advantage millimeter wave radio has over lower frequency microwave radio is its huge bandwidth potential. Millimeter wave radio solutions are capable of offering multiple gigabits of data capacity in a single link. Take for example Athena Wireless’ A060-Mini radio. The A060-Mini offers 1000Mbps full duplex, or 2000Mbps aggregate throughput, but only uses 550MHz of spectrum. Lower frequencies simply can’t achieve the same data rates as Millimeter wave radio.
Millimeter wave products can achieve a narrower beam width than lower frequency radios. Radios that take advantage of the narrow beam width of millimeter wave, such as Athena Wireless’ A060-Mini – which has a 2 degree beam width – benefit from increased interference protection and spectrum reuse. The highly directional and narrow radiation pattern from millimeter wave radios allows many radios to be deployed near each other without causing troublesome interference even when they are using the same frequencies. Using cross-polarization techniques allows even more radios to be deployed in an area, even along the same path.
Since millimeter waves have a narrow beam width and are blocked by many solid structures they also create an inherent level of security. In order to sniff millimeter wave radiation a receiver would have to be setup very near, or in the path of, the radio connection. The loss of data integrity caused by a sniffing antenna provides a detection mechanism for networks under attack. Additional measures, such as AES encryption, allow a network to be fully protected against attack.
As the frequency of a radio wave increases the size of the antenna needed to maintain gain decreases. The antenna size of a millimeter wave radio can be one-tenth or less the size of an equivalent lower frequency radio. Millimeter wave radio manufactures can take advantage of this property of radio wave radiation to build smaller, lighter systems. For example, Athena Wireless’ A060-Mini uses an integrated antenna that is only 7×7 inches (182×182 mm) but provides 37 dBi of gain.
In the United States, and many other countries, large portions of the millimeter wave spectrum can be used under only a light license or- as with the 60GHz band – under no license at all. Athena Wireless’ A060-Mini radio operates in the 60GHz band, and as such, can be deployed in the United States, Europe, and many other parts of the world without the need to register or license with any regulatory body. This provides a distinct advantage over other frequencies by way of quicker and simpler deployment and saved licensing cost.
Radio waves in various parts of the millimeter wave spectrum are more affected by atmospheric absorption – particularly oxygen and water absorption – than their lower frequency counterparts. While this may at first seem to be only a range limiting factor, it also provides a distinct advantage for radios using the affected millimeter wave bands.
Because of oxygen absorption, millimeter wave radios – particularly those using the 60GHz band – face lower interference than lower frequency radios. Other millimeter wave radios in the area of a receiver are not likely to interfere with the receiver since their signal will be largely degraded by atmospheric attenuation. These radios, such as Athena Wireless’ A060-Mini, are able to be deployed near each other and even along the same path, without the same levels of interference that other frequencies would face.
