2.4 GHz means its frequency is high but its wave length is very short so it can only covers only few meters like 50 to 100 only. But with the help of our high gain antennas we can extend these coverage but the thing is that they are not comes under Indian TRAI and DOT specified specifications like per channel what bandwidth can be used like 5 MHz to 25 MHz Max in India as per govt policy. So we can’t go against the govt policies other wise govt put fine.
For your unlicensed band 5.8 GHz it’s a very high frequency and it runs on LOS line of sight and it uses sector panel antennas. So we have some limitations because all wimax bases stations are not OFDMA and MIMO certified for signal rebusting like mobile wimax which is very costly for small operator and for big industry players to, but mobile wimax is not yet properly tested as per wimax it can works indoor also but this technology failed to work indoor.
The best now day’s available frequency is 2.4 GHz because this is the only equipment which can service NOLS client but only thing is that before starting it a person has to do a little field survey for other existing frequencies in the service area.
Now day’s equipments are available which can serve clients up to 1 Kms with high gain receivers like USB high gain wifi receiver which cost only 2500 to 3500. Where as for wimax CPE it cost more then 6500 and above…so which is cheaper. Wifi or Wimax.
For small operators wifi is the best choice you can charge your customer security deposit of 2500 to 3500 which is refundable at the time of surrender of the CPE back to you. You can but your terms like if we found that equipment is damage or not in working condition at the time if the termination of the connection then the deposit will be forfeited.
If any one is planning to start their ISP then they can contact me.., I will give you the full plan of mini WISP for 500 to 1000 customer’s project plan. With Wifi ISM band in 2.4. But a C class ISP license is to be obtained. You can get it by providing 3 Lakhs bank guarantee to govt DOT and annual fee of 2.5 percent of your turnover. Bank guarantee is only for your performance, govt want this guarantee for security of license which is given to you. If your performance is not satisfied then govt will incased this bank guarantee.
I think is information is sufficient for all who are planning to start their ISP business and for wireless questions.
