Re: Area coveragesaid by prairiesky:7800 mhz is also a weird frequency, not too many wifi devices operate there. said by Capricia :Its correct LLigetfa 7,800 MHz? HUH ??? Lutful might know, but I should don't know of any smartphones/laptops/USB adapters that work on that band. Do you mean 5,800 MHz? There are only a few smartphones up there, iPhone 5 (?) and Samsung Galaxy S4 and S5 do. There might have been a few USB adapters in the past year. 5,800 MHz is really, really not going to work without a clear line-of-sight, making it worthless for indoor or street level use.

I typo'd it, should have read 7,200 said by Capricia :Okay Chele you are an expert, the Area distance is 300 km square or km2 or whatever km sqr And how many Ap or base station should be built?
1.How many Ap or Bs should be built with 3 sectors antenna of 120 in one tower for example with 7200 mhz frequency 2. What is the formula for knowing how many Ap should be built in a given area? |

said by Capricia :300 km square ... 600.000 sub Just to clarify ... that is SIX HUNDRED THOUSAND subscribers. » Seting up wireless network covering 15km rangeFYI this dreamer wanted to cover same area, but with more realistic customer base. I wonder what happened to him, or the dozens of other dreamers who came here for advice on such ambitious WISP plans. Anyway, if you sincerely want to build a large urban WISP with many thousand customers, learn the basics of wired and wireless networking, and read relevant threads which discuss strategy. Here are some that I can think of quickly: 2006: » Mesh Network Simulation -- RMDLXOne of my posts have a diagram with a two level architecture required to support very large number of customers. 2008: » Planning a mesh setupmost relevant comment: Even with multiple radios assigned for backhaul duty, traditional mesh routing approach will not be best for such a scenario, but please read on for a hybrid PtMP+mesh suggestion ...
... if the remote node is on a building rooftop, you could deploy 4 separate dual-radio APs at the 4 corners.2009: » please help me i want to start wireless ispmost relevant comment: ... please understand that 1 km is almost beyond the limit for outdoor-to-indoor WiFi operation. You need to locate the APs on a taller building - put good quality 200mW TX power and -90dBm RX sensitivity radios with 90-degree sector antennas at the 4 corners of the roof or upper floor balonies.
You should ask customers to use USB WiFi dongles and point them through the window glass. For older wood shutter windows, just avoid the metal grills.2014: » [Equipment] Internet to New TownShipmost relevant comment: I advice against mixing fixed CPEs with laptops/tablet clients because of poor performance. But you can deploy separate dual-radio Mikrotik boxes as CPE+Hotspot for such clients.Older threads with relevant advice: » Vertical Separation» what tower/ap setup for this scenario?» Q: Maximum POP Customer Density and Tower AP Arrangements*** Do NOT choose Ubiquiti or any other brand of equipment BEFORE developing a comprehensive networking strategy and a viable business plan. *** You will almost certainly need custom wireless nodes with 6-8 sectors on MANY rooftops. Please go to a Mikrotik User Meeting (MUM) near you, and take their basic and advanced training ASAP. Even if you choose another company, you will learn a lot and meet many real WISPs. |

said by lutful:if you sincerely want to build a large urban WISP with many thousand customers, learn the basics of wired and wireless networking Actually I would suggest that if he wants a WISP with thousands of customers, he shouldnt be the one at the coal face. He should be employing people to run the coal face while he manages the business. Managing a network of thousands of users and all of the related carrier politics that will arise (peering and transit negotiations, faults and troubleshooting), while also managing a business of thousands of customers, and everything in between is not a one man job. Not if you value a quality operation anyway, or are some kind of superman. So I would say the next few words from the same sentence said by lutful:read relevant threads which discuss strategy are what he needs to do, then go hire the right people who can implement his vision. |

I'm sure the reality is the OP is just another example of one who thinks they can take three antennas and connect thousands of people. I'm surprised there has been as many posts in this thread as there have been. |

said by wirelessdog:I'm sure the reality is the OP is just another example of one who thinks they can take three antennas and connect thousands of people. There have been a few dozen threads like this since 2005. I will compile more links into an educational collection. Most OPs actually disappear after initial thread, but some do pursue their dreams to the business planning phase, and a few to the network planning phase. Reality bites them after setting up a few nodes in an urban area. Some adjusted their business plans with less ambitious subscriber goals, or moved their plans to nearby suburban/rural areas. They essentially become regular/normal WISPs. So there are benefits to providing guidance to such dreamers, no matter how ridiculous they appear in first thread. |

These people are from India or Africa if I remember, I gave them replies from continuous posts on the UBNT forum. Trying to explain that what they wanted to do was not realistic. They expected that we were going to provide the complete engineering for them for FREE! They kept asking the same questions over and over expecting to get the answers they wanted ! Got mad each time you told them something they didn't want to hear. All THEY wanted to hear was that they could buy a couple of radios, and cover the entire town on WiFi, connecting hundreds of devices, and making big bucks! (Why can't you tell us how to do this, you "Experts", if you can't tell us how to do this, you NO expert?) NOT GONNA HAPPEN! |

All they needs is three of these » www.wifi-shop24.com/24-G ··· mW-30dBmon channels 1, 6 and 11 with Omnis that will support thousands of users.. |

said by wtm:They also wanted to be the TV, and phone company over the WiFi ! Curiously my 2004 unlicensed band radio platform was designed to support 1024 simultaneous VoIP calls, with a lead customer who was in that business, and my 2009 updated design could broadcast 16 TV channels, in addition to those VoIP calls. The RF side used WiFi physical layer (PHY) chips, but the rest was implemented in custom FPGA. It is impossible to do that much parallel real-time traffic in a CPU. However impatient WISPs wanted to use whatever new WiFi-based radio was released by Deliberant, Tranzeo, HighGainAntennas, etc. ... and eventually started dreaming of doing "triple-play" using Ubiquiti. One of many such threads: » Using AirMax to provide triple play services? |
