FAQ: General Questions

Why the ACRS 2.0?

ACRS 2.0 is the latest generation TVWS product built upon Adaptrum's innovative adaptive OFDMA platform, delivering unmatched rate versus range performance and interference resilience in the TV bands worldwide. The earlier generation Adaptrum TVWS system, ACRS 1.0, is the first cognitive radio system certified by the FCC and has been used in trials and demos around the world. Built upon the success of ACRS 1.0 and with significant performance and feature enhancements, ACRS 2.0 is the second generation Adaptrum TV White Space product specially targeting volume production and outdoor deployment.

Has ACRS 2.0 been field tested?

Adaptrum has been shipping ACRS 2.0 radios to our preferred customers since the beginning of 2014. Hundreds of ACRS 2.0 radios have already been deployed in 15 countries across 4 continents. Radios have been running stably for more than 6 months now.

Do I need a license to operate ACRS 2.0 radios?

ACRS 2.0 is certified with Google TVWS and Iconectiv TVWS databases for commercial use in the US. US customers do not need an experimental license to operate the ACRS 2.0 radios. International customers need to consult with their radio spectrum regulators to obtain proper licenses to operate the ACRS 2.0 TVWS radios in their countries.

FAQ: Technical Questions

What range can I expect from ACRS 2.0?

Range is heavily dependent on terrain and foliage. It also depends on channel frequency and background noise level. In most of our deployments, typical NLOS range is between 2 to 5 miles. Many ACRS2.0 radio links deployed have distances in excess of 5 miles. The longest distance reported by our customers is 12 miles.

What throughput can I expect from ACRS 2.0?

With 6 MHz channel size, the measured TCP throughput is around 10 Mbps in good link conditions. With 8 MHz channel size, the measured TCP throughput is around 14 Mbps in good link conditions.

What latencies can I expect from ACRS 2.0?

Under standard settings, the expected latency through the ACRS 2.0 radio system is between 10 to 20 msec.

How many clients can one base station support?

Up to 12 clients may be supported by one base station on a single TVWS channel depending on your deployment environment and the distances between clients and base station, as well as your general network design.

What is the download/uplink ratio for ACRS 2.0?

Normally, ACRS 2.0 dynamically adjusts downlink/uplink ratio based on network traffic to optimize the link usage. But you can also manually select the ratio to fit your application requirement using Adaptrum’s network management software.

What TVWS databases are supported?

Adaptrum equipment works with TVWS databases that are certified with our equipment. Currently, Google and Iconectiv TVWS databases are certified for use with the ACRS 2.0 system.

What antenna types are supported?

ACRS 2.0 supports various UHF antennas including log-periodics and panels. Adaptrum can provide both types of antennas, which have been tested.

Can I use my own UHF antenna?

Adaptrum cannot guarantee optimal performance with every UHF antenna on the market. For this reason, we are supplying an Adaptrum qualified UHF antenna with all of our radios.

Does ACRS 2.0 support channel bonding?

ACRS2.0 support channel bonding up to a maximum supported bandwidth of 10MHz.

How are software updates pushed?

Software updates can be pushed through our cloud-based network management software as well as local instances of the management software with a direct connection to the unit.

How do I perform network management?

A benefit of Adaptrum’s solution is our cloud-based network management system, which will allow you to monitor and configure all of your radios remotely.

How do I know the client is connected?

Client connection status can be monitored through Adaptrum management software.

Will I know the quality of a channel?

Yes, Adaptrum management software has spectrum analysis capability and can provide estimates for each TVWS channel.

Can I remotely reboot ACRS 2.0?

Yes, ACRS 2.0 can be remotely rebooted manually through the management software.

Does ACRS 2.0 support adaptive modulation?

Yes, ACRS 2.0 automatically adjusts modulation depending on varying channel conditions.

What device categories are available in the ACRS 2.0 product family?

Currently, ACRS 2.0 only has a fixed version available. A personal portable version will be available in late 2014.
