General Interest / Specifications

What radio should I use? Why not use a Wi-Fi system?


Call a representative at AvaLAN Wireless at 650-384-0000 ext. 201. WiFi systems generally are less secure and may not work well due to radio saturation and interference. The range is also reduced due to the wider spectrum and higher frequency being used.

Why didn’t my radio come with a product manual?


Manuals are in digital format only readily available from the AvaLAN website.

What is the IP Finder Utility?


AvaLAN’s IP Finder Utility are windows based programs that will discover AvaLAN Wireless radio’s on a Local Area network.

Can the 5.8GHz 100Mbps radio pair with the 5.8GHz 300Mbps radio?


No, it’s not supported.

Do I have to use the POE provided with the radio?


AvaLAN radios use forced POE injection and do not respond to 802.3af or 802.3at supported POE switches. A POE convertor is required to power an AvaLAN radio. Part # AW-POE-CON

Can I power the radio using a POE switch?


AvaLAN radios use forced POE injection and do not respond to 802.3af or 802.3at supported POE switches. A POE converter is required to power an AvaLAN radio. part # AW-POE-CON

What is the range of a non-line-of-sight scenario?


Every non-line of sight is unique and the range depends on how many obstructions are in the way, and the size, shape, and density of each obstruction. Foliage is easier to penetrate than a building.

Do these radios have Wi-Fi signal?


No, the operate using proprietary wireless communication.

How long can the networking cable be between the POE injector and radio?


For the 100 Mbps radios: cable length using shielded CAT5 or CAT6 cable is maximum 300 ft. For the 300 Mbps radios: cable length using CAT6 cable is maximum 50 ft. For the 1 Mbps radios: cable length using shielded CAT5 or CAT6 cable is maximum 300 ft.

Can a bridge pair become a point-to-multipoint configuration?


AW900xTR and AW2400xTR can be reconfigured for point-to-multipoint configuration. AW58x00 series: Due to licensing and legal requirements, bridge pairs cannot be configured as point to multi-point. To create a point to multi-point system, you need to buy unpaired radios.

Can I protect the radio against lightning damage?


Yes, there’s protection on both the ethernet and antenna side available.

Which antennas will achieve the maximum range?


Directional antennas are best for maximum range.

Can the system route packets between subscribers?


Yes, the AP monitors Ethernet traffic from each SU and transmits it to the appropriate destination, either another SU or into the network.

How many Ethernet devices can I attach to each subscriber unit?


A total of 128 Ethernet devices are supported per access point. A subscriber unit has one Ethernet port and can connect to an Ethernet switch to aggregate multiple Ethernet devices.

How does a point to multipoint system work?


A point to multipoint system uses one access point (AP) radio with up to 16 subscriber radios (SU) to create a multipoint network link extension. Each SU must be individually keyed to the AP before installation. After key exchanging the installation is simple, fast, and requires very little technical skill compared to other Ethernet products on the market today.

Each AP continually monitors the SU until data is transmitted or received. When data is to be transmitted either from the AP to the SU or vice versa the data is encrypted, transmitted, decrypted, and fed into the network.

What is the speed of the RJ45 Ethernet interface?


The radios use a 10/100 full duplex interface with exception to the AW58300 and AW58303 radios which use a gigabit interface.

At what voltage do the radios operate?


It depends upon the product.

At what temperature range do the radios operate?


-40° C to 70° C (-40° F to 158° F)

How much latency or lag occurs during the delivery of packets?


AvaLAN’s products use a proprietary communication protocol that has an exceptionally low latency and very high payload efficiency. The systems latencies are appropriate for video conferencing, surveillance video, VOIP applications, and even head to head gaming.

How do the radios handle encryption?


All AvaLAN products use at least a 128-bit AES FIPS 197 NIST certified encryption protocol. We also offer radios that are NIST certified FIPS140-2 Level 2 encryption.

How can I know what channel is the best to use?


Each AvaLAN radio is designed to find the best frequency/channel available. If the radio is having a hard time doing this because of interference, it has built-in tools such as a sprectrum analyzer to observe channel behavior and allow you to choose the best channel manually. The process depends on which model radio you are using. Details may be found in the instruction manual which may be downloaded from the product page.

How do the radios handle retransmission of packets with errors?


AvaLAN products use a sub-block retransmission protocol rather than a full packet retransmission protocol. AvaLAN’s Smart Packet Fragmentation protocol breaks large Ethernet packets into smaller sub-blocks. If any sub-block has an error only that block is retransmitted instead of the whole packet.

How do the radios handle interference in unlicensed spectrum?


AvaLAN products operate in 900 MHz, 2,4 GHz and 5.8 GHz bands. Unique to AvaLAN products is our frequency intelligence that merges the best of Frequency Hopping with Direct Sequence radio architecture. AvaLAN’s protocol continuously monitors the error rates of each packet to determine the quality of the link. If the error rate increases due to interference the AvaLAN product will autonomously change channels. With 12 channels at 900MHz, 29 channels at 2.4 GHz and up to 9 channels at 5.8GHz the AvaLAN solution can intelligently adapt where frequency stagnant or random hopping systems fail.

How can I determine the terrain profile along my transmission path?


There are a handful of software tools that will help with design. Google earth is an example of a easy to use tool. We recommend using a program such as Google Earth to view the terrain that you will be working with.

Configuration / Troubleshooting

How do I perform a factory reset?


If you need to perform a factory reset, call Technical Support at 650-384-0000.

How many subscribers can I connect to each access point?


All access points can connect to up to 16 subscriber units, with exception to the AW900F and AW900FS radios, which can connect to up to 4 subscriber units.

My radios are not connecting. What should I do?


Verify network name, encryption key, frequency and device ID all match. Refer to manual for specific programming instructions.

Does it matter which side is the access point, and which is a subscriber unit on a point to point configuration?


Under normal circumstances it does not matter which side is the subscriber, and which side is the access point. The both act as transceivers, pushing and pulling the data.

Should I use fixed or dynamic IP addresses?


Best practice is to use a fixed IP address.

How do I perform remote diagnostics?


Each radio has a Browser Interface by which one can manually reconfigure the radio and view the data statistics.

Can I add new radios to an existing AP? Can an SU become and AP and vice versa?


All radios with exception to the bridge pairs can be used to expand the existing wireless network. To add new radios to the network, simply key the new subscriber unit to the existing access point, ensuring that the Network Name, Encryption Key, and Channel are identical to the those of the radios of the existing network. Only the 900MHz and 2.4 GHz radios have the option of switching from a subscriber to an access point and vice versa. the 5.8GHz radios do not have that capability.

How do I align the antennas?


There are several methods for antennas alignment. LED’s and the embedded web interface will help with alignment.


What video settings work the best?


All Ethernet protocols are supported. However TCP and H.264 are settings we recommend.

Can the system handle multiple network cameras transmitting back to the same AP?


Yes, so long as the combined data rate from the cameras does not exceed the radios’ capabilities. A rule of thumb is to imagine only having 60% of the aggregate bandwidth (180 Mbps for a radio with 300 Mbps aggregate bandwidth) available through the AP or divided among the SUs. As long as the cameras operate within the bandwidth budget they can be combined in a point to multipoint configuration. For example, if your system contains 3 cameras on a 300 Mbps radio, each camera must be set to require a maximum of 60 Mbps.

How do I transmit analog video over digital Ethernet radios?


Two Options:

Use a video server that converts analog video data to Ethernet data packets.

Use a network enabled DVR that buffers the analog video data for later transmission over Ethernet.


How many VoIP phones can be used simultaneously?


Testing has shown that up to 14 VoIP phones can work simultaneously with the point-to multipoint system. For the test, one VoIP phone was connected to each subscriber unit. The subscriber units were all linked to the same access point. 14 VoIP phones were able to join a conference call successfully.

Digital Signage

How much data can be pushed to the signs in 24 hours?


With regards to the 900MHz and 2.4GHz radios (excluding the AW900f and AW900FS), a point-to-multipoint system uses bandwidth that provides approximately 7.5GB per day. 16 digital signs w/ subscriber radios & 1 access point, you could deliver 465MB per sign; 7.5GB per day.

How many digital signs can be used simultaneously?


16 digital signs can be used simultaneously with the point-to-multipoint system; one subscriber unit per sign.

Access Control

Do the radios support RS232, RS485, Wiegand, TTL, or USB?


We have a RS232 (AW900R2-PAIR) point to point option. A RS485, Wiegand, TTL, or USB to Ethernet converter will enable functionality with AvaLAN systems. For converters see

What if access control devices make data requests simultaneously?


The point-to-multipoint protocol would separate the requests, and each request would appear on the network side of the access point one at a time. The access control server would then handle each request.

How many IP enabled access control devices can I use simultaneously?


16 access control devices can be used simultaneously with the point-to-multipoint system. Door open response time: AvaLAN’s point-to-multipoint system uses a special polling technique to minimize latency and provide robust data communication to each individual subscriber unit. With 16 door authentication devices each with its own subscriber unit and one access point, the door open response time would be approximately 1 second.

Mobile Applications

Can an access point connect to another access point?



Can a subscriber unit connect with multiple access points simultaneously?


No, the subscriber unit can only hold encryption keys for one access point at a time. However, copies of an access point can be created, and the subscriber would be able to connect to any of the duplicates if the original access point fails.
