Residential and business users are progressively more dependent on reliable Internet connections as the world is becoming more digitised. Currently, entertainment, communication, smart home appliances and security technology make use of the Internet. Additionally, according to a joint 2019 Globalwebindex and Reddit report, the global online community is growing but changing. With declining membership of real-world social groups, clubs, and local organisations, people are turning to online communities to experience a sense of belonging.
These trends point to an intensifying need for stable and reliable Internet connections and people are asking more questions about the differences between ADSL, fibre, and LTE.
Asymmetric Digital Subscriber Line (ADSL) is a type of Digital Subscriber Line (DSL) broadband communications technology used for connecting to the Internet. Compared to traditional modem lines, ADSL allows more data transfer.
ADSL data transfer consists of electrical signals transmitted over copper telephone lines and thus, users with existing wiring into their premises, will not require any additional installations to obtain an ADSL service. However, a microfilter needs to be installed to allow concurrent ADSL and regular voice (telephone) services routed by the telephone lines of a subscriber.
ADSL subscribers must be located within a radius of 3 to 5 kilometres of the nearest geographical location of a provider to have access to ADSL services. They also need a special ADSL modem which typically supports data transfer rates of from 1.5 to 9 Mbps when receiving data (or downstream rate) and from 16 to 640 Kbps when sending data (or upstream rate).
Increased traffic generated by users in the same neighbourhood can cause congestion or bottlenecks. Also, since copper telephone cables were never intended to meet the demands of modern Internet usage coupled with speed limitations, users find the data transfer rate increasingly unacceptable. Cable theft also increases the challenges associated with copper lines. Because of the cost in their replacement, downtime and unreliable service add to the unavailability of services.
