Wireless Mesh Technology - What is it?

Posted by Amy Cavaliere on Wed, Apr 21, 2010 @ 11:04 AM

There has been a lot of talk lately about wireless mesh technologies.  Because of this, there is a tremendous amount of information available for it, enough to confuse even the best of us.   I have been reading up about it (I figured as the marketing person I should since we sell it and I wanted to learn about it without having to ask my tech support and sales guys) and finally have it broken down to what I consider to be understandable terms (coming from a non technical perspective that's asking a lot). 

According to "a mesh network is a local area network (LAN) that employs one of two connection arrangements, full mesh topology or partial mesh topology. In the full mesh topology, each node (workstation or other device) is connected directly to each of the others. In the partial mesh topology, some nodes are connected to all the others, but some of the nodes are connected only to those other nodes with which they exchange the most data. " 

Ok so now I had the definition but what exactly does it do?  So I kept digging and I came across this great article that really breaks mesh down and explains it in laymans terms so I thought I would share. explains that "Wireless mesh networks can easily, effectively and wirelessly connect entire cities using inexpensive, existing technology. Traditional networks rely on a small number of wired access points or wireless hotspots to connect users. In a wireless mesh network, the network connection is spread out among dozens or even hundreds of wireless mesh nodes that "talk" to each other to share the network connection across a large area."  The article has plenty more information so check it out and drop a comment to let me know what you think about mesh.

Digital Two Way Radios: The Future of Professional Radios

Posted by Amy Cavaliere on Mon, Apr 19, 2010 @ 16:04 PM

Television turned digital, music turned digital and now two-way is going digital as well.  As a user of two way, you may ask yourself "why should I go digital? Why should I invest in the new technology when my analog radios are working just fine?"

Well, there are many features and advantages that digital radios can offer that your run of the mill analog ones can't.  Digital radios work with a greater spectrum efficiency which in turn allows for a higher calling capacity.  They provide enhanced signaling for user-friendly operation, they enable flexible privacy between individual users and groups, and they combine voice communication and wireless data applications in the same device. 

Digital radios can save you money.  Because of the technology used, there is a calling capacity double that of analog radios.  This creates two virtual channels while allowing a company to only pay the price of one "real" channel license.  It also elminates the need for an additional repeater or combiner system for the second call.  With digital radios battery life is also increased by approximately 40% leading to less costs incurred for replacing batteries.

With analog radios, signals are often distorted creating audible static.  Some digital systems have the ability to surpress background noise at the transmitter which are therefore not heard at the receiver.  They can also provide voice and privacy without requiring extra hardware or altering the quality of the transmission. Motorola has a great example of the sound quality difference between analog and digital radios. Click Motorola hear the difference to check it out.

Converting your radio fleet from analog to digital is simple and can be done over time.  There are devices that can offer both analog and digital modes in a single unit.  By choosing these units, companies can gradually convert to a digital system when the time is right for them.
