  2. Agenda • What’s new in wireless? • Is there a “silver bullet”? • Making the best of what you have • Lessons learned

  3. What is new in wireless? • Devices are new • Networks will remain the same on all vendors for the next 12- 15 months. • Voice networks will remain the same • Mobile broadband technology will continue to be built out (from an tower network approach) however no change to the product- EVDO-Rev A and 3G

  4. Point of reference

  5. ATT Mobility (http://www.wireless.att.com/home/) • Network- GSM –Global System for Mobile Communications • Voice frequency – GSM • Data services – GPRS, EDGE, UMTS, 3G.

  6. ATT Mobility coveragehttp://www.wireless.att.com/coverageviewer/

  7. Verizon Wirelesshttp://www.verizonwireless.com/b2c/index.html • Voice frequency is CDMA – (code division multiple access). Verizon is now an all digital network. Most handsets no longer have an analog frequency • Data Frequency- 1xRTT, EVDO- Rev0, EVDO- Rev A

  14. What to do improve what you have • PRL (preferred roaming list) updates. - Verizon & Alltel= *228 (send) Select prompt 2- “update roaming” - Sprint- *2 (send/talk), then prompt 3, followed by prompt 3 again.

  15. What to do improve what you have • PRL updates continued: ATT Mobility & T-Mobile- power off device for @ 10 minutes. Power up device- this will cause the device to register to the network.

  16. Antenna’s are line of sight.

  17. Line of sight & terrain • Hills • Valleys • Building clutter • Tunnels

  18. Brick cement & rebar Sheet rock Glass Trees Leaves Rain/Fog Attenuators-that reduces the amplitude or power of a signal without appreciably distorting its waveform

  19. Asymmetrical trees!

  20. Lessons Learned • Abbreviated cell phone battery life • Trees in Texas • All digital vs. tri-band

  21. Looking forward • LTE-4G future technology for ATT & Verizon Wireless (in 3-5 years) (http://www.phonemag.com/att-verizon-google-discuss-fcc-700mhz-auction-042235.php) • XOHM by Sprint (http://www.xohm.com/learn-overview.html)
