This was the worst experience ever buying a computer. The owner misrepresented the computer he was selling, tried to sell me a bootleg MS operating system and when I told him the things the computer would not do he blamed me for it. He promised a gaming computer and sold me an e-machine. I had to buy a new power supply and a new video card in order to bring this computer up to the point the owner said it was capale. When confronted with his misrepresentation , he said, "It will play some games". There wasn't a truthful word come out of this man's mouth. I have submitted a Better Business Bureau complaint. Get everything in writing because this man's word is worth diddley! ...read more

My laptop had become infected with a lot of viruses and I didn't have the money to get it fixed that is when a friend told me about Micro Esc Technology Solutions. So I took my laptop in and low and behold their price was only $59.00! They had my laptop done in less than 24 hours now I am virus free and still have money for food. Will go back again!

Hello? Can you hear me now? Hello? Can you hear me NOW? Does this sound familiar? Weak cellular signals and dropped calls are frustrating for business owner, employees, and mobile users who spend hours a week in their vehicles. DAS Networx designs and installs distributed antenna systems (cellular signal boosters) that amplifies the weak signal and then distributes the signal inside your office or in your vehicle. The signal is also amplified as it is sent back out to the tower. Not only is your signal stronger, decreasing dropped calls, but is also extends your battery life as well. Your phone uses less power to transmit your signal. We also have systems to boost your 4G/LTE signal also. Call us today at 405.445.3456 to find out how DAS Networx can help "raise the bars" at your business. Serving Oklahoma, Texas, and South Central Kansas/ ...read more

A DAS Network consists of three primary components: (i) a number of remote communications nodes (DAS Node(s)), each including at least one antenna for the transmission and reception of a wireless service provider̢۪s RF signals; (ii) a high capacity signal transport medium (typically fiber optic cable or low loss Coax) connecting each DAS Node back to a central communications hub site; and (iii) radio transceivers or other head-end equipment located at the hub site that propagates and/or converts, processes or controls the communications signals transmitted and received through the DAS Nodes. Depending on the particular DAS Network architecture and the environment in which it is deployed, DAS Nodes may include equipment in addition to the antennas.DAS Network can be deployed outdoors or within large buildings and partially enclosed structures, and a DAS Network can range from two to hundreds of DAS Nodes. Each DAS Node typically transmits RF signals at much lower power levels than is common for macrocell sites. Outdoor DAS Nodes are typically attached to utility poles or similar structures in the public rights of way (PROW) at heights that are relatively low and uniform, consistent with the smaller coverage area for each DAS Node. DAS Networks are attractive solutions because they are scalable and flexible. Like macrocell sites, DAS Networks can be configured to support multiple wireless service providers deploying a variety of frequency bands and wireless service technologies in a small form-factor. While DAS Networks are often driven by the same radio transceiver equipment that is used with macrocell sites, DAS solutions enable these resources to be narrowly targeted to the areas where they are most needed and the capacity can be shifted to different parts of the DAS Network as subscriber locations and demands shift.

The FCC passed a new regulation that will go into effect March 2014 that will ban inferior amplifier products that do not meet FCC and Carrier guidelines. Many knock-off manufacturers are offering "cheap" deals on inferior signal amplifiers and making it appear as though one size fits all. This is NOT the case. These inferior system will be allowed to be "disabled" by carriers. It takes site surveys of multiple signals, building design considerations, knowledge of all cell towers for all carriers in the area, and the engineering knowledge to properly configure the system output to operate correctly as well implementing proper grounding/surge protection to safeguard the equipment. Being one of the owners and Sr. Solutions Architect of DAS Networx, I personally have been in the IT / Technology arena dating back to 1990 serving in the U.S. Army in secure communications in Germany during the Gulf War (5 Yrs total). Besides having a Degree in Network Information Systems, certifications with multiple Voice System Companies, a member of BICSI (Building Industry Consulting Services), and certified installer of structured cabling systems, I can assure you DAS Networx provides professional products and services that be "raising the bars" for businesses throughout the region. We look forward to providing our customer with the best products and services for years to come. ...read more
