Wimax vs. Long Term Evolution - 929 Words

Wimax vs. LTE: LTE and Wimax are 4G technologies. LTE is Long Term Evolution project which is been proposed by 3GPP (3rd generation partnership project) which is nothing but collaboration between various telecommunication companies. So LTE has its background from the GSM technology. Wimax is IEEE 802.16 standard and it’s mainly roots in CDMA. Frequency of operation: LTE operates at lower frequency as compared to wimax. Higher the frequency of operation, higher the attenuation. Both wimax and LTE uses OFDM (Orthogonal Frequency Division Multiplexing). OFDM uses orthogonal frequencies as carrier frequencies so that there will be no interference between the signals i.e. it uses the principle of orthogonality. This in turn improves the spectral efficiency. Multiple Access: Both LTE and wimax uses MIMO (Multiple Input Multiple Output), which a Space Division Multiple Access technique. It is a smart technique in which the same signal is transmitted in different streams to the receiver. The receiver choses the best of the transmitted signal streams and decodes the signal. It is chosen such a way that, the best quality signal is obtained. So, even the weaker signals are boosted up by this technique. Infrastructure: Both LTE and wimax uses ip infrastructure. The flat structure of ip helps the mobile as well as the base station. Latency: Latency is less in LTE when compared to wimax. Range: Theoretically LTE has better rang than wimax. Speed: speed of LTE is way higher thanShow MoreRelatedNetwork Speed - 4G Technologies Essay1402 Words   |  6 Pagessystems, short range wireless connectivity and wired systems will be combined into a complimentary platform. 2.

However IP based mobile isn’t perfect and has its own host of problems and those will be discussed as well later as well as possible fixes in short and long term to these problems. The main need to implement mobile IP is the fact that it can support more users and keep those users closer to the internet, meaning that the internet is integrated into the system. This can cause some issues with connectivityRead MoreSpectrum For Wireless Broadband : Old Media Vs New Media1836 Words   |  8 Pages Case: Spectrum for Wireless Broadband: Old Media vs New Media †¢ Question 1 : As an Apple or Verizon executive, what legislation would you propose to the house and Senate committees to advance the reallocation of spectrum to wireless broadband?
