We spent the afternoon adding capability to the Angola Assemblies of God website.  The email system of the hosting ISP had been down for a month or more.  We added a new domain name and email service from another ISP (bugflicker.com) and had the email operational in 2 hours.  There still remains an issue with the smtp but it works OK for me via my broadband provider.  Now comes trying to pry away the original domain name from the errant ISP.  That should be fun.

 

Later we designed a local area wireless distribution system to provide >2 mile hotspot transmission/reception for a customer's marine application (High Gain ship wireless device.pdf ).  That was a fun job and it is at the stage we can start to build the prototype.  The production cost has to be less than $350 so it adds a little challenge.

We have been busy for the past couple of weeks on projects.  Currently we are working with TR Water Services in Miami on their website.  We have added a form on the Contact page that has Captcha security.  Also we have added a player on the Products page that plays a video (a very large video 44Meg) about some of their products.  Thanks for the business Roger.

 

As you know we have migrated more and more to website design and development so that we are able to reduce our travel.  After 20 years of almost constant travel in the wireless and 2 way business we are looking for a place to light for a while.  We are concentrating on SMB websites and are very responsive and cost effective - our rates reflect our low overhead - so you save lots of $$ using us for your websites.

 

 

I have been studying Wilson Electronic cellular dual band signal boosters.  They are BDA's of higher quality than the lowest price units.  An installation of these devices would cost approximately $1000 to $2000 for a standar type house SOHO application.  What do you get for these $$$?  You get a strong cellular connection in remote or under-covered cellular areas.  For example. in my office I receive my Verizon signals is some areas and not in others.  If I installed the device under discussion, I would receive a strong signal and have excellent voice/data transmission rates.

 

If you are a long way from a cell site(s) of any type and multiple cell vendor coverage (e.g. Verizon/AT&T) is required then multiple high gain antennas might be necessary.  This would add cost and complexity.  However, if only one vendor is needed then one high gain antenna would lessen cost.  This all points the necessity of performing a "site survey".  These are divided into two stages - preliminary and detailed site surveys.

 

The preliminary site survey (PSS) is used to determine if the installation is at all feasible and to document a few facts as to location, obstructions and other general details.   The detailed site survey (DSS) is much more detailed and covers building construction, mounting points for antennas, power sources and equipment locations.  The DSS also documents the azmuith and distance to the required cellular towers but this could be part of the PSS.  Both the PSS & DSS could be performed at the same time depending on the complexity of the proposed system.

The Zircon stud finder has a small learning curve but it is important to find a good "calibration" area.  Otherwise false alarms will occur.  It took a few anomolies to determine  I was not getting a good calibration.  Also, do not remove the instrument from the wall after calibration.
