And the part 15 type B certification is a self certification process with no filing needed with the FCC and there for no FCC id number provided. Majority of the testing is line noise testing ie what possible signals the device might be outputting into the electrical grid. That is where the most stringent requirements are on a type B device.
Your mixing up the type class B certification with full Part 15 certification testing. Yes the crossroads and the rb411r have full certification because they have transceivers that needs certified built on to the unit. But a regular class B device does not. Just take a look at any regular computer part with exception of a radio card or modem. You will find NO FCC id's on any of those devices but more than likely you will find a FCC logo on them to indicate that the testing been done and that the device passes and the manufacturer have the testing documentation in their own company files. Class A restrictions are lower than Class B restrictions because they are expected to be used/installed by professionals while a Class B device is installed by the less technical knowledged. Take a regular computer for example the parts and pieces are Class B certified yet you can use a computer in a business/commercial environment because a Class B device exceeds the Class A requirements. / Eje -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of ralph Sent: Wednesday, September 16, 2009 12:22 PM To: 'WISPA General List' Subject: Re: [WISPA] backhaul choices Don't forget that routerboard is a computer. It does more than enable the wireless card. It needs to have a Part 15 computing device certification as well, just like your PC. So regardless of the radio card and the antenna and any of the rest of the things that people are disagreeing on, it still boils down to a fine for the user if the RB causes interference and is found to be not certified. If some of you were around when PC clones were being first built, we had these computer shows and fairs and even some Hamfests where the local pc builders were showing their wares. A popular PC case was a convenient flip top affair that allowed easy access to the cards inside without using screws. The FCC made many a visit to these shows, shutting down and fining the builders of these systems. They did not build the motherboard and they did not build the case, they just *assembled* it, just like you folks are doing with the Mikrotik stuff. As far as I can tell from the FCC info, only 2 routerboards have any FCC Part 15 Class A or B computing device approval. They are the Crossroads and the RB411- both of which already have on board wireless. I will quote part 15.3 here and you can decide whether or not your routerboards are required to be certified. If I were you, I would demand that MT have all their computing devices certified. ======= Digital device:ยง 15.3 (k) Digital device. (Previously defined as a computing device). An unintentional radiator (device or system) that generates and uses timing signals or pulses at a rate in excess of 9,000 pulses (cycles) per second and uses digital techniques; inclusive of telephone equipment that uses digital techniques or any device or system that generates and uses radio frequency energy for the purpose of performing data processing functions, such as electronic computations, operations, transformations, recording, filing, sorting, storage, retrieval, or transfer. A radio frequency device that is specifically subject to an emanation requirement in any other FCC Rule Part or an intentional radiator subject to Subpart C of this Part that contains a digital device is not subject to the standards for digital devices, provided the digital device is used only to enable operation of the radio frequency device and the digital device does not control additional functions or capabilities. Note: Computer terminals and peripherals that are intended to be connected to a computer are digital devices. Class A digital device: A Class "A" digital device is a digital device that is marketed for use in a commercial, industrial or business environment. Class B digital device: A Class "B" digital device is a digital device that is marketed for use in a residential environment. Examples of such devices include, but are not limited to, personal computers, calculators, and similar electronic devices that are marketed for use by the general public. Class B equipment, intended for use in a residential environment where the likelihood of RFI is greater, must meet much stricter RF emission limits than the Class A devices. ======= -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dennis Burgess Sent: Tuesday, September 15, 2009 7:32 PM To: WISPA General List Subject: Re: [WISPA] backhaul choices The way I understand it, the routerboard don't matter, the antenna, and radio matters, as its certified as a system, with xx gain of this type of antenna. You also have to have the FCC information, etc, on the outside that MT offers to only its distributors. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jerry Richardson Sent: Tuesday, September 15, 2009 6:12 PM To: WISPA General List Subject: Re: [WISPA] backhaul choices That's been the ongoing argument. I use the analogy of a PCMCIA or USB card. that's the device that is FCC certified - the computer (routerboard) just runs it. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Tuesday, September 15, 2009 2:53 PM To: WISPA General List Subject: Re: [WISPA] backhaul choices Excuse my ignorance but since the card is the only thing that transmits why does the board and especially why does the enclosure need to be certified? If one puts a two way radio in a car the radio needs to be certified, not the whole car.
