New Airmux-400 from RAD
Posted by John Brandon in General, Wireless Muliplexers on February 25th, 2010
OK, it’s been a while since I last posted about the virtues of wireless networking, I admit. Since my last post, I have been busy with a lot of different aspects of this industry. RADWin and RAD Data Communications have since released the latest version of their wireless bridge called the Airmux-400 which now supports asymmetric speeds of up to 100 Mbps in one direction with a lower speed in the opposite direction. By offering the capability of both symmetric (50 Mbps in both directions) and asymmetric, RAD has maintained the standard 20 MHz channel bandwidths thus preserving the total number of non-overlapping 20 MHz channels available. And, the Airmux-400 ships with selectable 5.3, 5.4, and 5.8 GHz bands (4.9 is also available in addition for public safety) right out of the box.
I’ve also learned the new Airmux-400 hardware that supports 100 Mbps asymmetric speeds will soon support 100 Mbps full duplex symmetric. It will require double the channel bandwidth (40 MHz), but the benefits will outweigh the loss of some non-overlapping channels. And with so many different bands to choose from, I don’t think it will be an issue anyway.
If you haven’t deployed wireless networking where possible with RAD Airmux-400s yet, you should look at the possibility. A system can be deployed in a few hours and it can save you a bundle over the long run. I’m talking thousands to hundreds of thousands of hard dollars.
All the information on the Airmux-400 as well as all of RAD’s products can be seen on out sister site www.RADProductsOnline.com.
Broadband Wireless Bridges Eliminate Recurring Costs

New generation unlicensed, carrier-class Ethernet radios replacing T1 and T3 leased lines
In the new era of connecting the LANs of remote facilities together, the Telcos don’t want you to know about point-to-point broadband microwave bridges. Why? Becuase the Telco’s bread and

butter business is selling bandwidth in the form of T1, T3, and Sonet leased lines. Over the years, business has tried various methods of “bypassing” the Telcos by installing their own dry copper or dark fiber where possible. Until 8 years ago, connecting remote offices or facilities amounted to dialup ISDN at 128 kbps or on the high-end, T1 circuits running at 1.544 Mbps. Neither was a great choice for bandwidth-hungry Ethernet applications, but they were faster than anything else at the time. Anyone who ever had to pay for one knows they can get very pricy. And the cost goes on and on indefinately month after month.
Always looking for a better and faster way, manufacturers began offering wireless devices for the 802.11 WiFi market that could be “stretched” in some cases to go a little farther. But not until the 5 GHz frequencies were opened up did any of that really matter. Read the rest of this entry »
