Solution
Bottleneck is a time during processes when something causes the process to slowdown or stop all together.
Some cases the WiFi signal broadcast by the Cradlepoint router will interfere with the WiMAX signal that the devices use if they are too close to each other.
Actually, the problem is the Wi-Fi signal most of the time. The upper bands of the 2.4. GHz spectrum (Wi-Fi) and the lower bands of the WiMAX (2.5 GHz) can overlap because Wi-Fi radios are not very highly controlled on how they can cause \"radio wave pollution\". If WiFi work at 2.5GHz and WiMax work at 11 GHz should be no problem.
But changing to Wi-Fi Channel #1 or #2 is a major step to improving signal. CradlePoint router\'s warn you about that. If your WiMAX modem is plugged in, and you go to the tab at the top that says status, I\'ll see a big warning, saying \"Use WiFi Channel 1 or 2\" or something like that.
In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is small cell, with femtocell as a subset. It is also called femto AccessPoint(AP). It connects to the service provider’s network via broadband (such asDSL or cable); current designs typically support four to eight active mobile phones in a residential setting depending on version number, and eight to 16 active mobile phones in enterprise settings. A femtocell allows service providers to extend service coverage indoors or at the cell edge, especially where access would otherwise be limited or unavailable. Although much attention is focused on WCDMA, the concept is applicable to all standards, including GSM, CDMA2000, TD-SCDMA, WiMAX and LTE solutions.
Use of femtocells benefits both the mobile operator and the consumer. For a mobile operator, the attractions of a femtocell are improvements to both coverage, especially indoors, and capacity. Coverage is improved because femtocells can fill in the gaps and eliminate loss of signal through buildings. Capacity is improved by a reduction in the number of phones attempting to use the main network cells and by the off-load of traffic through the user\'s network (via the internet) to the operator\'s infrastructure. Instead of using the operator\'s private network (microwave links, etc.), the internet is used.
Higher mobile data capacity, which is important if the end-user makes use of mobile data on his or her mobile phone (may not be relevant to a large number of subscribers who instead use WiFi where femtocell is located)
The placement of a femtocell has a critical effect on the performance of the wider network, and this is the key issue to be addressed for successful deployment. Because femtocells can use the same frequency bands as the conventional cellular network, there has been the worry that rather than improving the situation they could potentially cause problems.
