Maximising Signal Strength Inside Buildings For Wireless LAN Systems Using OFDM
White Papers OFDM allows a base station to transmit and receive the same signal at the same frequency from multiple locations, at a low cost and without detrimental effects of Inter-Symbol Interference (ISI). Propagation inside buildings suffers from large...

Signal Strength Measurements In GSM TEMS Mobiles
White Papers A TEMS mobile has no hardware modifications at all compared to a standard (non-TEMS) Ericsson mobile phone. This means that no additional calibration has to be done after the TEMS software has been loaded.

Minimizing Calibration Effort For An Indoor 802.11 Device Location Measurement System
White Papers However, this level of accuracy comes at the price of a manual, tedious, spatially high-density calibration of signal strength as a function of location. The algorithm uses an interpolation function that gives location as a function of signal...

Throughput Unfairness In TCP Over WiFi
White Papers The paper investigates how throughput is divided among the participating wireless hosts with respect to signal strength, traffic direction and use of the RTS/CTS mechanism. The study shows that while competing clients with comparable signal...

IPhone 3G Reception Problems: Your Information, Please
Blog If you enter *3001#12345#*, you'll go into Field Test Mode, where one of the indicators is the signal strength in dBm, or decibel milliwatts. Anything below around -100 dBm is not good -- radio engineers, preferring consistency to clarity, work in...

802.11-ngratitude
Blog Comment My next router, a Linksys WRT54GX4 with "SRX400 Speed and Range Extension" was able to reach the ground floor, but only with medium signal strength. The signal strength is indeed better, even compared to the SRX400 router; I typically get Good or...

Netgear WNDR3300 RangeMax Dual Band Wireless-N Router
Blog As soon as I went down one floor, to the bedroom level, the -G network (2.4GHz) signal strength was noticeably higher than the -N network (5GHz), but both were still usable, and of course the -N was still faster.
