    • About American Cellphone signals
      Americas In North America, GSM operates on the primary mobile communication bands 850 MHz and 1,900 MHz. In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band. In the United States, regulatory requirements determine which area can use which band. GSM-1900 and GSM-850 are also used in most of South and Central America, and both Ecuador and Panama use GSM-850 exclusively (Note: Since November 2008, a Panamanian operator has begun to offer GSM-1900 service). Venezuela and Brazil use GSM-850 and GSM-900/1800 mixing the European and American bands. Some countries in the Americas use GSM-900 or GSM-1800, some others use three: GSM-850/900/1900, GSM-850/1800/1900, GSM-900/1800/1900 or GSM-850/900/1800. Soon some countries will use GSM-850/900/1800/1900 MHz like the Dominican Republic, Trinidad & Tobago and Venezuela. In Brazil, the 1,900 MHz band is paired with 2,100 MHz to form the IMT-compliant 2,100 MHz band for 3G services. The result is a mixture of usage in the Americas that requires travelers to confirm that the phones they have are compatible with the band of the networks at their destinations. Frequency compatibility problems can be avoided through the use of multi-band (tri-band or, especially, quad-band) phones.

    • Poland 4g LTE
      Poland’s Office of Electronic Communications (UKE) is expected to launch the auction of 800MHz and 2600MHz Long Term Evolution (LTE) 4G mobile spectrum early next month, according to a report from RPKom. Six firms have already pre-registered as bidders: existing cellular providers Orange Polska, T-Mobile Poland, P4 and Polkomtel, plus Hubb Investments, which is controlled by broadcast infrastructure firm Emitel, and NetNet, which is owned by the son of a senior Polkomtel executive and business partner of Polkomtel shareholder Zygmunt Solorz-Zak. As stated in TeleGeography’s GlobalComms Database, the regulator is offering five 2×5MHz lots of paired spectrum in the ranges 791-816MHz and 832-857MHz, and 14 lots of 2×5MHz between 2500-2570MHz and 2620-2690MHz. The licences will be valid for 15 years and cover the entire territory of Poland. Bidders are limited to a maximum of two 2×5MHz blocks of 800MHz frequencies and four 2×5MHz packets at 2600MHz. Additionally, successful bidders that already use frequencies in the 800MHz or 900MHz ranges will be not be allowed to exceed a combined total spectrum holding of 40MHz in those bands. A minimum price of PLN250 million (USD66.5 million) has been set for each packet of 800MHz spectrum, while the minimum bid for lots in the 2600MHz band is PLN25 million.

    • Wifi signals
      Wi-Fi, also spelled Wifi or WiFi, is a local area wireless technology that allows an electronic device to exchange data or connect to the internet using 2.4 GHz UHF and 5 GHz SHF radio waves. The name is a trademark name, and is a play on the audiophile term Hi-Fi. The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on theInstitute of Electrical and Electronics Engineers' (IEEE) 802.11 standards". However, since most modern WLANs are based on these standards, the term "Wi-Fi" is used in general English as a synonym for "WLAN". Only Wi-Fi products that complete Wi-Fi Alliance interoperabilitycertification testing successfully may use the "Wi-Fi CERTIFIED" trademark.
