Perkembangan Jaringan Nirkabel tahun 2010 dan beberapa tahun kedepan : HSPA+ , LTE , Wimax

USB Wireless Network / USB dongle telah menjadi perangkat pendongkrak popularitas 4G bersama dengan CPE (Customer Premise Equipment) dan laptop. Akan tetapi, handset mobile akan menjadi kunci keberhasilan WiMax. Sebagai contoh, Yota (Rusia), Sprint dan Clearwire (Amerika Serikat) telah menyediakan layanan mereka dengan perangkat dari HTC dan Samsung.

Di saat yang sama, operator mobile juga terus berusaha mendapatkan lisensi LTE (Long Term Evolution). Sekitar 20 operator diperkirakan akan meluncurkan layanan mereka pada kuartal keempat 2010 mendatang. LTE sendiri merupakan Next Generation dari GSM setelah HSPA+

Evolusi GSM, Perkembangan GSM, Perkembangan Teknologi GSM

LTE capabilities:


  • Downlink peak data rates up to 326 Mbps with 20 MHz bandwidth


  • Uplink peak data rates up to 86.4 Mbps with 20 MHz bandwidth


  • Operation in both TDD and FDD modes


  • Scalable bandwidth up to 20 MHz, covering 1.4, 3, 5, 10, 15, and 20 MHz in the study phase


  • Increased spectral efficiency over Release 6 HSPA by a factor of two to four


  • Reduced latency, up to 10 milliseconds (ms) round-trip times between user equipment and the base station, and to less than 100 ms transition times from inactive to active
 
Cakupan layanan LTE memang belum akan menyaingi WiMax, akan tetapi pada akhir kuartal keempat 2012, diprediksikan sekitar 600 juta pengguna akan dapat menikmati layanan tersebut.

Pasar 4G akan mencapai 150 juta pelanggan di akhir tahun 2014 mendatang. Adapun pangsa pasar antara WiMax dan LTE akan tergantung pada komitmen operator WiMax untuk mengupgrade ke 802.16m.

Vendor MiMax seperti Motorola dan Huawei sendiri sedang menyiapkan perangkat 802.16e+ yang akan membawa fitur-fitur 802.16m ke pasar. Sejumlah perusahaan di ekosistem ini sendiri sudah mulai mengujicoba interoperabilitas untuk 802.16m.

ABI Research sendiri telah mengumpulkan data kota-kota dan populasi yang tercakup layanan 4G selama setahun terakhir. “TD-LTE merupakan kuncinya,” kata Jake Saunders, Vice President for Forecasting ABI Research, seperti dikutip dari PCAdvisor, 14 Mei 2010.

“Meski awalnya ditujukan sebagai teknologi evolusi untuk TD-SCDMA bagi China Mobile, teknologi tersebut meraih minat sejumlah operator WiMax,” kata Saunders. “Kedua kubu (WiMax dan LTE) akan berusaha secepat mungkin menyelesaikan produksi chip, portofolio produk dan cakupan layanan. Akan ada persaingan yang keras dalam beberapa tahun ke depan,” ucapnya. (hs)



Informa forecasts that, even including fixed and mobile WiMAX, subscriptions will reach only 5 percent of the global 3G market by 2013, with 103 million connections. Forward Concepts predicts 38 million WiMAX subscribers by 2012, while Juniper Research forecasts 47 million WiMAX subscribers by 2013 –compared to nearly 1.8 billion UMTS-HSPA subscriptions by 2013 according to Informa.

Agree, looks to me like you are doing excellent work with all the detail on those houses. Don't short-cut yourself without trying animals or portraits. You already are doing lots of shading and detail.

Hal ini juga berguna bagi mereka yang memiliki jaringan nirkabel, karena menyediakan peta untuk jaringan Anda. Harga program ini adalah sekitar 40 dolar.

Operators who will soon provide a "truely all IP Next Generation Network" can quickly adopt WiMAX 802.16e because this system has operated well and tested, and available terminal equipment (CPE) that can access through WiMAX modem (in the form of a USB dongle) or have be embedded in laptops, netbooks, Smartphones, iPad, iPhone, Android HP, etc.. Another alternative is to wait 1-2 years until the operation of the network and CPE LTE terminal that is expected to start in 2011.
