Structure

As defined in the National Telecommunications Policy (1998) and the International Long-Distance Telecommunications Services (ILDTS) Policy (2007), all mobile operators must interconnect through Interconnection Exchanges (ICXs), while all international calls are to be routed through International Gateways (IGWs), which connect to both mobile and fixed operators via the ICXs. The Interconnection Exchange (ICX) will receive all calls from the mobile and fixed operators whenever the call is made to another network and will pass it to the destination network if the call is local, and will pass to the IGWs if the call is international. ICX will also deliver calls received from IGWs where the call is destined. Below illustrate the structure of interconnection between different interfaces.

Service providers

Public switched telephone network The number of public switched telephone network (PSTN) subscribers in Bangladesh as of February 2009 was 1.372 million. PSTN operators in Bangladesh include:

Mobile phone operators

There are four mobile phone operators in Bangladesh, operating under the names of Banglalink, Grameenphone, Robi and TeleTalk. The number of mobile phone subscribers in Bangladesh as of April 2015 was 124.705 million, having risen from the February 2009 figure of 45.21 million. As of September, 2022 the number of mobile phone subscriber has risen to 181.43 Million. [1]

Long distance operators (as per ILDTS Policy 2007) On 25 February 2008 the Bangladesh Telecommunications Regulatory Commission awarded licenses for two Interconnection Exchanges (ICX), three International Gateways (IGm), and one International Internet Gateway (IIG) to six firms through an open auction in February 2008. The incumbent BTTB got the same licenses too. And after then on 12 April 2012, the Bangladesh Telecommunications Regulatory Commission awarded licenses for twenty-one Interconnection Exchanges (ICX), twenty two International Gateways (IGw), and thirty International Internet Gateway (IIG). Here is the list of all operators:

Worked examples

Example 1 — a first encounter with Telecommunications in Bangladesh

Start with the simplest possible case. Write down what Telecommunications in Bangladesh claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telecommunications in Bangladesh before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telecommunications in Bangladesh ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telecommunications in Bangladesh

In research: Telecommunications in Bangladesh appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telecommunications in Bangladesh in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telecommunications in Bangladesh is common in secondary-school and first-year university syllabi. It links to neighbouring topics Telecommunications in Bangladesh, so understanding it makes those chapters shorter.
In everyday life: Look for Telecommunications in Bangladesh outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
