How is 4G LTE Different from GSM ?

by

We’d like to draw parallels and compare and show to readers How 4G LTE is Different from GSM. The underlying multiplexing schemes in both 2G (GSM) and LTE appear similar: in both cases, multiple users are handled by ensuring that no two users send messages on the same frequency bucket at the same time (i.e., both technologies use a combination of frequency division and time division).

However, GSM is quite rigid in its resource allocation: a user is assigned one frequency bucket at the start of the session and he gets to send messages within that frequency bucket once in every eight time slots. Further, the allocation is frozen at the beginning of the session and remains fixed throughout the session.

700MHz Spectrum Better than 1800MHz for 4G LTE

by

For telecommunication starters, the 700MHz digital spectrum has better propagation than higher frequency spectrum such as 1800MHz spectrum, and better in-building coverage. The cost of achieving equivalent network coverage is significantly lower using 700MHz spectrum compared to 1800MHz. However, risks would revolve around the evolution of the eco-system for 700MHz. If it becomes a key … Read more

Optus & Telstra 4G in 1800Mhz Band

by

Vodafone Hutchison Australia [VHA] is facing increasing investment requirements to catch up to its competitors with regard to network quality, and also to renew and acquire the spectrum needed to remain competitive. There’s an ongoing perception of VHA’s network quality relative to those of Telstra and Optus, as well as fallout from the step-change in … Read more
