In the last article, we checked the impact of communication on the development of the country.

so today let’s talk about the current communication development in Bangladesh.

In this “[Future Impact of 4G on Business in Bangladesh])” report:

Current Situation of 4G and Its Impact

Bangladesh performs close to the regional averages across metrics of mobile market development, despite having lower income than neighboring countries.

Notably, Bangladesh is above the regional average in subscriber penetration, while only slightly below in mobile internet and in the proportions of 3G and 4G connections.

CONCEPTUAL FRAMEWORK

Fiber optic networks and their role in 5G

Fiber optic networks are a type of high-speed wireline network offering improved speed, security and bandwidth over legacy copper systems. Fiber optic technology has long been used in long-haul networks due to its high performance over long distances — fiber can travel as far as 40 miles without losing signal strength.

Now fiber is increasingly being used in metro and access networks instead of copper. And because copper can only carry a gigabit signal about 300 feet, many businesses choose to continue the fiber connection all the way to their premises — called a fiber to the premises (FTTP) configuration — to avoid losing signal strength. In essence, fiber optic networks are limited only by the technology used to transmit and receive signals.

In an ideal world, every phone, smart sensor and mobile device could be directly connected to the fiber backbone — but that would limit the mobility of the devices. That’s where 5G wireless network technology comes in. 5G networks will essentially be designed to bridge the short distance between a mobile device (as in 5G mobile services) or business (as in 5G fixed broadband) and the fiber backbone.

The essential relationship between fiber optics and 5G wireless networks

5G wireless small cells and their fiber wireline networks will never be mutually exclusive. To understand the relationship between wireless and wireline networks, it’s helpful to think of a city’s network in physiological terms: 5G will function splendidly as the capillaries (mobile fronthaul) of a city’s networking system — but internet traffic will travel nearly its entire journey in the veins or arteries (fiber backhaul).

In fact, much like the human bloodstream, only about 11% of traffic is carried by wireless networks, according to a study by Deloitte. The other 90% of internet traffic is supported and carried by the wireline network.

So in a 5G world, the customer experience will be improved by better small cell wireless access points. But ultimately, the quality and reliability of the wireless network will depend on the wireline (fiber) network carrying traffic to and from the 5G small cells.
