SAF microwave radios are suitable for up to 100+km link distances depending on various factors, such as Line of Sight, the required data speed, location (rain zone), elevation of the sites and others. Often it is more economic to split up a very long path into two shorter ones.
Maximum data speed of SAF radios is 883Mbps full duplex per radio, that`s 883Mbps in each direction of transmission. This is possible with a 112MHz channel size which can only be used in licensed 28GHz in Australia.
80MHz is available in 11GHz and 6.7GHz, this allows to achieve up to 643Mbps full-duplex. The same speed can be achieved with class-licensed 24GHz radios.
56MHz allows to achieve 473Mbps full-duplex and is available in 6GHz, 18GHz and 23GHz.
Smaller channel sizes are available from ACMA in other frequency bands.
2+0 configuration can be used for doubling data speeds if faster data speeds are required. This configuration also provides redundancy.
Main benefit of using licensed microwave radios is interference-free operation. Obtaining a frequency channel license from ACMA provides exclusive rights of use of this channel in the particular area.
Other benefits of licensed microwave radios over class-licensed radios include faster data speeds, longer distances, much lower latency, a range of extra features, 1+1 and 2+0 configurations and others.
An exception is SAF 24GHz class-licensed radios- these provide the same data speeds and features as licensed radios and risk of interference is very low, however, due to ACMA limit on radiated power for this frequency band, it is only suitable for very short distances.
ACM stands for Adaptive Coding and Modulation.
In situations when link conditions worsen (typically due to environmental conditions) to the extent where a link with the same availability level without ACM would drop service, SAF radios with the ACM feature automatically switch down to a lower modulation (and lower throughput) to preserve the link data operation. As soon as environmental conditions have improved, ACM automatically switches back to the original modulation and data speed.
This allows to achieve higher link availability figures (significantly reducing or often eliminating any link downtime) as well as reduce antenna sizes.
ACM is available with all SAF radios.
Power consumption of radios varies for different models and frequency bands. Overall, the FODUs (Full Outdoor) radios draw a lot less power than the traditional indoor plus outdoor solutions and are the best option for solar powered sites. Some of the radios draw as little as 15W per unit.
Available interfaces include Fast Ethernet, electrical Gigabit Ethernet, optical fibre Gigabit Ethernet (single mode or multi mode), E1, STM-1, ASI.
Spectrum licensing involves the following fees and charges:
1. ACMA application charge – $202.00 (GST free) per link
2. Spectrum allocation charge- typically $500.00 (plus GST) per 1+0 link
3. Annual ACMA license fee- this annual tax varies between under $100.00 and over $25,000.00 per 1+0 link per annum depending on:
The process of applying for an ACMA license is very simple and typically takes less than a week- once we have decided on the frequency band, channel size and antenna sizes that would work best for you, we can proceed with spectrum coordination and apply for the licence on your behalf. You then receive an invoice from ACMA for their fees and charges, and once this has been paid, licences are typically issued within a couple of days.
Maximum EIRP (Equivalent Isotropically Radiated Power) figures for class-licensed radios are as follows:
EIRP is radio tx power plus antenna gain minus any losses.
It’s rare that you find any two installations the same, but we’ve removed the variables to give a simple answer to this question.

Yes, all microwave radios require clear LOS to operate, except very low frequency bands, such as 1.4GHz- 1.5GHz that can operate in NLOS (near line of sight) conditions. If you have a NLOS path, please contact us and enquire about the SAF CFIP Marathon 1.5GHz radios.
Yes, we do offer a link design service and this service is available free of charge or obligation. We will be happy to assist you with path profiles and link uptime calculations as well as selection of repeater sites, if required. We will also recommend the most suitable radio equipment, frequency band, channel size and antenna sizes based on your specific requirements and circumstances.
Yes, we do provide installation and maintenance services. These will typically be performed by ourselves in NSW, ACT and VIC (often in conjunction with other local companies as we strongly believe in local first level support) and by our partners in SA, WA, NT and TAS. If you have a preferred local installation company, we will be happy to work with them and provide training and any other support required.
Yes, we do keep local stock of radios in our NSW warehouse to ensure very fast deliveries for most orders. Our stock includes the most popular radio models and frequency bands- 1.5, 6, 7, 8, 11, 13, 15, 18, 22/23, 28GHz licensed and 24GHz class-licensed.
Typical lead time for items not available from stock is 5 to 6 weeks, some equipment can take longer.
