Long Term Evolution

Long Term Evolution a.k.a LTE, is one of the emerging technologies in 4G mobile communication which is being globally adopted by most of the telecom equipment vendors and operators. This technology promises the broadband speed 10 times faster than the current 3G network is supporting. The LTE network offers 5-12 mbps downlink speed and 2-5 mbps uplink speed which will decrease the latency in real time applications, online gaming, connected to a virtual clinic and telematics.

LTE promises a very low latency and high bandwidth. This will set the mobile networks suitable for accessing real time applications where responsiveness is very critical. With this technology you can think about the things like taking high definition videos and streaming it to others mobile across the country, multiplayer online video games with your friends in remote locations, live camera broadcasting etc...

LTE provides a global ecosystem where everyone can tap into using the laptops, personal computers, smartphones and other consumer electronic equipments. It will allow the business customers to connect to the office systems, teleconferencing, video collaborate, stream database applications and other applications to which we had bandwidth and security constraints earlier.

The first LTE network was launched in December 2009, by TeliaSonera and only a few operators have followed the suit. Why operators are waiting to adopt LTE even though it is the next big evolution in the mobile technology? This could be because of the lessons learned from the early 3G front runners who suffered after implementing the expensive networks but had very few compatible devices in the market.

However, LTE offers the equipment vendors a unique opportunity to create a long term relationship with operators and its associated companies. The early adoption of LTE has the advantages like capture the highest-spending users market, improve the brand equity by projecting as a technology leader, gain better knowledge and experience in the technology than its rivals. In addition to the these advantages the early migration will lower the CAPEX over time through long term partnerships and lower the OPEX by integrating the existing networks into single core network earlier than the rival operators.

Some of the vendors & operators Launched LTE are given below.

      NetCom (TeliaSonera) – Operator (Norway)

     Telia (TeliaSonera) – Operator (Sweden)

     Vodafone – Operator (Germany)

     Verizon Wireless - Operator (US)

     Ericsson – Network Vendor

     Huawei – Network Vendor

     NSN – Network Vendor

Near Field Communication

When you are walking across the street, the mobile phone starts giving you the sales information in the shops. Is it going to happen in the near future? Yes, it is the power of technology and consumerism. The near field communication technology (NFC) lead us to a new platform where your mobile phones can be used to read the RFID tags from the shops/billboards and give you more information about the sales. To realize the NFC services in mobile phones, an NFC mobile phone should be able to utilize the functionalities of a contactless card and a mobile phone.

NFC is a short-range wireless technology. The equipments enabled with NFC, contain a transmitter and receiver to send and receive data from other NFC enabled equipment. Multiple devices in a small area can communicate with each other using the same frequency.

Google included support for NFC in the Android 2.3 Gingerbread operating system and this functionality is also included in the Nexus S smartphone. The other smartphones enabled with NFC technology are Nokia C7, Nokia Astound, Samsung Galaxy S II, Samsung Wave 578.

Few applications based on NFC are given below (from wiki).

  • Mobile ticketing in public transport: an extension of the existing contactless infrastructure, such        as Mobile Phone Boarding Pass.
  • Mobile payment: the device acts as a debit/credit payment card.
  • Smart poster: the mobile phone is used to read RFID tags on outdoor billboards.
  • Bluetooth pairing: in the future, pairing of Bluetooth 2.1 devices with NFC support will be as easy as bringing them close together and accepting the pairing. The process of activating Bluetooth on both sides, searching, waiting, pairing and authorization will be replaced by simply bringing the mobile phones close to each other.
