Why LTE ?

The first question that comes in our mind is, why we need of the LTE network?
It is very simple to answer this question in today's world, where we are talking a real time gaming, IP TV, High Definition video on demand, Multi user gaming over IP, Live TV, Live Video Conference and much more things. If you have to experience these services with the quality of services and new services, thus we need LTE should come in to picture. LTE satisfies the wireless broadband requirements instant on, always on and multi magabit throughput.
The improved speed and low latency provided by LTE will offer a much improved end-user experience for all corporate services:

• For applications where data throughput is important - faster e-mail and file uploads, enhanced VPN connection, high-speed internet, etc.
• For interactive applications where latency is crucial - IMS based VoIP, mail and file synchronization with an on-line server, peer-to-peer applications such as “Net Meeting”, SIP multimedia services including video and voice conference over IP, application sharing, etc.
  

LTE Characteristics:

• Peak LTE throughput's
            − DL: 100 Mb/s SISO (Single Input Single Output);
            − 173 Mb/s 2x2 MIMO (Multiple Input Multiple Output);
            − 326 Mb/s 4x4 MIMO; for 20 MHz
            − UL: 58 Mb/s 16 QAM
            − 86 Mb/s 64 QAM (based on 1 Tx UE)
• Ultra Low Latency
  − less than 10 msec for round-trip delay (RTD) from UE to
    server
  − Reduced call setup times (50-100ms)
  − =>wired user experience
• Capacity Per Cell
  − 200 users for 5 MHz, 400 users in larger spectrum
