Technology Corner: A Look Into License Free Radio Spectrum World Wide |
In an Era of IP network explosion, the license-exempt wireless communication platform has expanded its role beyond simple voice communication. It has reached the mass market segment to provide a reliable alternative to hardwiring for voice over IP, IP TV, and security applications to name a few. There are several great reason why wireless is a preferred medium over hard wiring. Wireless is economical, faster time to deployment, secure, and reliable. In many cases, wireless is the only option. License exempt wireless is available worldwide in several frequency bands. The most popular and uniformly accepted is 2.4GHz frequency. 2.4 GHz frequency allocation is adequate for voice and data communication therefore usage of cordless telephones and wireless computer access points worldwide find their home in this band. Among other license free bands, not all are uniformly acceptable worldwide. National restrictions may limit or omit the use of certain frequency bands for one country versus another country. The following map provides a rough overview of license free frequencies supported or not supported worldwide.
Figure 1. License Free Bands of the World - A Rough Overview
When considering wireless communication for security applications, there are two wireless technology options, proprietary or standardized. The install base for proprietary wireless technology is small and costly relative to standardized wireless technology based on Wi-FI (802.11). Wi-Fi is well proven and readily available since late 1998. It is also one of the most successful industry standards in history. Wi-Fi is experiencing rapid advancement with newer extensions released to enhance wireless performance. WiMax is another wireless standard rapidly gaining grounds and hold a lot of promise for the licensed bands. However, the industry anticipates cost effective WiMax equipment to emerge within a few years time frame. Long range wireless equipment by Inscape Data based on WiFi is available today and brings host of benefits to the security market. Table I provides a rough overview of license free bands and characteristics and use of each band if available in your deployment region.

Table I. License Free Frequency Review (FSO, Free Space Optics)
Illegal or improperly use of license free radio equipment is a federal offense and extreme care should be considered when using it in your country. Confirm with national authorities when in doubt if a particular frequency band is considered license free or when a new frequency band will be available in your region. The following table provides information on fourteen regional spectrum management authorities and their website.

Table II. Country or Regional Radio Spectrum Authority
Radio transmission power and antenna gain combination or EIRP at specific frequencies are primary technical considerations in deploying license free radio equipment. EIRP stands for equivalent isotropic radiated power and is defined by each country's spectrum authority. In the United States, equipment operating on 2.4 GHz frequency may not exceed a maximum of 36 EIRP for point to multipoint communication as stated in the FCC part 15 rules. License free radio spectrum is a great tool for the industrial, medical, and scientific community for the advancement of cost effective radio communication technology. After all, wireless is economical, faster time to deployment, secure, and reliable. In many deployment scenarios, wireless is the only option.

Help Desk : Can a High Power AP with 1W Max Tx Power Cover 5 Mile Radius? |
The most common question asked for the Inscape Data sales team is how far can the radios reach? This is a very valid question because if the wireless signal reaches short of the receiving radio, zero communication happens. Although an Access Point maybe specified for 5 miles, care should be considered for duplex or two ways data communication links. In a nutshell, wireless duplex communication requires two or more devices to handshake. For duplex radio handshake, two main criteria must be met. 1st and foremost, The Tx power, the transmit signal power, need to be strong enough to reach the receiver and 2nd the Rx power, receive signal power; need to be above the receiver's threshold level. Often the misconception if the one end of the equipment can support a specified distance, the other end of the link may also support it. This is entirely true if the equipment on both end of the link is identical in specification. The assumption would need to be further considered if the equipment on both end of the link is dissimilar. The following scenario illustrates dissimilar equipment for a point-to-point link using one AB54E Pro and one notebook computer with integrated 802.11g. Table I summarizes the wireless signal reach for each equipment.
2.4 GHz Equipment |
Tx Power |
Antenna Gain |
EIRP |
Theoretical Line of Site Maximum Distance Reach |
AirEther AB54E PRO |
30 dBm |
6 dBi |
36 dBm |
6 Miles / 10 km |
Wireless Notebook Computer |
16 dBm |
2 dBi |
18 dBm |
0.5 Miles / 1km |
Table I. Theoretical Distance Reached
The equipment in the table can transmit a signal of 6 miles and 0.5 miles theoretically. The limiting factor in this scenario is the wireless notebook with weaker Tx power and lower gain antenna. The maximum theoretical communication distance between the AirEther AB54E Pro and wireless notebook computer is 0.5 mile, the least common denominator.
There are other critical considerations for successful and reliable communication techniques including but not limited to interference, line of site, frequency band, cable loss, and weather. In most cases, shorter distance links are more tolerable than long distance links. Many of these details and wireless training are covered in the Inscape Data Certified Professional Training.
