1) If you are a real Internet Service Provider you will need a minimum block of public IP's from Arin, "Minimum is 2048", static, public IP's. Bec-Tel filed with ARIN but they are not using it. It cost about $800.00 US to do this. Bec Tel is or was working with Centennial / Viva to get bandwidth. Why don't they use it? Cost, Technical capacity, or both?
2) Bec-Tel is using license free frequency, But they do have a block in the 3.5GHz that they rarely use ( I think they are trying to sell the block ). ( The block was originaly assign to them to provide rural telephony. They cheated the goverment and there for the Dominican People, they used Tricom cellular network to use in the Public Telephone. The smart people in Indotel should know this. To my understanding they are also thief of the Dominican People using the ignorance of low knowledge technical people in INDOTEL. ). Again they are a Joke or people with little or no Cash using license free equipment, taking advantage of the Dominican people.
3) OneMax is using 3.5GHz. Every Base Station has capacity of OC-3, most of the Backhauls are licensed, but they are also using License free 300Mbps backhaul. Wind-Telecom is trying to make things work in the 2.5GHz.
4) Again every one in the DR is using Arcos as the Internet Service provider, buying bandwidth in DR is expensive. It looks like OneMax has 45 Mbps total.
5) It's not Orange fiber ( They have capacity for 72 SMF, repeating in Bonao and Santiago, capacity could be of 720 Gbps ). You hit it!, they are not buying enough bandwidth.
6) You are correct, I should have said Claro or Better yet Nortel HSDPA network in DR.
OH, yes the infrastructure that the company you said is not a joke, Bec-Tel, looks nothing like the installations you see Claro, Codetel, Tricom, Orange, Viva, OneMax and Wind Telecom are using. Again Bec-Tel is not only a Joke, they are cheating the Dominican People.
