wimax vs LTE
This page on wimax vs LTE describes difference between wimax and LTE. Both wimax and LTE are used for providing broadband wireless internet services.
wimax is the completely new standard developed for providing high data rate
internet services. wimax is designed for only data applications.
As it is entirely new technology without any legacy support,it is very costly and
requires service provider to install all the equipments.

LTE follow cellular standards such as HSPA, WCDMA, GSM etc but it is
designed mainly for data applications. It is also referred as all IP data network.
Voice over LTE is also possible using legacy fall backs and using VOIP protocols.
Due to predecessors existing equipments can be make use of and hence it is less costly and requires
minimum initial investment.
