One of my mobile broadband Internet provider (EVDO Rev A) planned to close its service in a near future, due to Qualcomm has decided to stop EvDO evolution. The service has real unlimited budget-plan. Currently most of mo-bro providers (both CDMA and GSM) in here are moving to early stages of 4G LTE (either FDD or TDD).
So the impact is, many BTS (base transceiver station) nearby my house have been sold, signal was going worse. Several months ago my EvDO modem (without external antenna) could easily resonated at -70 dBm of HDR power. But since the collapse was announced, signal was suffering at only around -85 down to -90 dBm typically.
(with external antenna, signal can be received at -50 dBm, but I prefer the antenna for another HSPA+ service)
Fortunately I keep an old unused indoor TV antenna. Sure it's dedicated for lower frequency band for TV broadcast. While that my dying ISP works at higher 800MHz of carrier frequency.
Hoho... then I imagined to build a simple dipole antenna to recycle that my old antenna.
