ARS Technia has a very informative article on unifi pro gear in a home environment. Very good, but long read.
MTIN is announcing changes to our pricing structure effective March 1, 2019. In order to simplify things, we are consolidating into two different pricing structures.
$139 per hour during normal business hours (8am-5pm EST time)
$159 per hour for after hours and weekend
First come first serve. No SLA.
Minimum of 1 hour
Normal Business Hours (8am-5pm EST time) $91 per hour
Late night & Weekend support $110 per hour
Must Purchase in 6-hour blocks ahead of time to meet response times below for any non-scheduled work. After hours work can be scheduled ahead of time for normal business hour pricing.
All contract customers will incur a minimum of 1 hour per month.
Normal working hours (3-hour maximum)
Late night and weekend (4-hour maximum)
All existing customers with time balances will not be affected at this time.
For customers who need specific projects, we offer our 6-hour block of time at a discount of $89 per hour. There is no SLA includes as projects are agreed for a completion date when taken on. Project rates do not include support on anything but the project. If additional support is needed it can be billed at the above rates.
Projects are negotiated on a case by case basis based upon the scope of work, time frame needed, and other circumstances.
Welcome to the second month of 2019. I have some exciting changes coming which will make this a more exciting year. These changes will affect how MTIN does business. As many of you have noticed I am doing more Youtube and similar projects. These will be increasing. Look for more product reviews, deep dives, and educational videos.
MTIN will be cutting down on the amount of available consulting time for new clients. For a long time now I have believed the best way to help network operators is to have a tighter relationship with those whom I support. This means getting more and more involved in their networks on a regular basis. As a result, the pricing structure will change somewhat.
The first change will be dropping of the tiered support model. We will now have contract and non-contract customers. More on this in a different post. Secondly, I have taken on a more active role with a couple of clients here in Indiana. This means I am dedicating more time to their networks. Networks are becoming more and more complex and having a consultant that understands both the technical and business aspects is very helpful to you as a network operator.
Does this mean MTIN is not taking on more consulting business? No, but it it means I am more selective on the projects and clients I bring on. MTIN is not a big consulting firm, nor do I wish to be. As many of you have seen I launched the JSW consulting brand awhile back. You will start to see more and more distinction between MTIN and the JSW brand. Look for some new web-sites coming shortly.
Over the next few weeks, I will be finishing up some projects on the plate for current customers. After that, look for some exciting announcements.
Recently, there have been some discussions on Facebook about waining support for 2.4GHZ . KP Performance recently published a Future of 5GHZ and beyond blog post. So why all this focus on 5GHZ and why are people forgetting about 2.4?
To answer this question, we need to update our thinking on the trends in networks, not just wireless networks. Customers are demanding more and more speed. Network backbones and delivery nodes have to be updated to keep up with this demand. For anything but 802.11 wifi,2.4GHZ can’t keep up with the bandwidth needs.
One of the significant limitations of many 2.4 radios is they use frequency-hopping spread spectrum (FHSS) and/or direct-sequence spread spectrum (DSSS) modulation. Due to 2.4GHZ being older, the chipsets have evolved around these modulation methods because of age. When you compare 2.4GHZ to 5GHZ radios running OFDM, you start to see a significant difference. In a nutshell, OFDM allows for higher throughput. If you want to read all about the differences in the protocols here ya go: http://www.answers.com/Q/Difference_between_ofdm_dsss_fhss
Secondly, is the amount of spectrum available. More spectrum means more channels to use, which translates into a high chance of mitigating interference. This interference can be self-induced or from external sources. To use an analogy, the more rooms a building has, the more simultaneous conversations can happen without noise in 2.4GHZ we only have 3 non-overlapping channels at 20mhz. Remember the part about more and more customers wanting more bandwidth? In the wireless world, one of the ways to increase capacity on your APs is to increase the channel width. Once you increase 2.4 to 30 or 40 MHz, you do not have much room to deal with noise because your available channels have shrunk.
One of the biggest arguments in support of using 2.4GHZ for a WISP environment is the physics. Lower frequencies penetrate trees and foliage better. As with anything, there is a tradeoff. As the signal is absorbed, so is the available “air time” for transmission of data. As the signal travels through stuff, the radios on both sides have to reduce their modulation rates to deal with the loss of signal. Lower modulation rates mean lower throughput for customers. This might be fine for customers who have no other choice. This thinking is not a long term play.
With LTE especially, the traditional thinking is being uprooted. Multiple streams to the customer as well as various paths for the signal due to antenna stacking are allowing radios to penetrate this same foliage just as well as a 2.4 signal, but delivering more bandwidth. These systems are becoming more and more carrier class. As the internet evolves and becomes more and more critical, ISPs are having to step up their services. The FCC says the definition of broadband is at least 25 meg download. A 2.4 radio just can’t keep up in a WISP environment. I am seeing 10 meg becoming the minimum customers want. Can you get by with smaller packages? Yes, but how long can you maintain that as the customer demand grows?
So what is the answer? Cell sizes are shrinking. This is helping 2.4 hold on. The less expensive radios can be deployed to less dense areas and still provide decent speeds to customers. This same trend allows 5GHZ cells to be deployed as well. With less things to go through, 5GHZ can perform in modern networks at higher modulation rates. Antenna manufacturers are also spending R&D to get the most out of their 5GHZ antennas. More money in the pipeline means stronger products. My clients are typically deploying 3.65 and 5GHZ on their towers. LTE is changing RF WISP design and taking the place of 2.4 and 900.
We are trying out something new. This is aimed at a quick burst of information for ISPs, network operators, and those involved in supporting networks. These “flash briefings” are aimed to be 2-5 minutes in length. iTunes and other subscriptions coming shortly.
In this flash briefing:
ISPs, the deadline for form 477 is March 8th.
