What affects speeds on my iPhone VPN!
Actual data transfer rates of your iPhone VPN will vary depending on many factors. The main factors include your ISP (Internet Service Provider), Wi-Fi or the cellular network, iOS (Apple’s Operating System) and the chipset in your phone. In addition, the server connections on your iPhone VPN have their own set of variables.
Therefore, two people in the same park using the same Wi-Fi and the same iPhone VPN service provider, but with different iPhone models can experience very different speeds. By the same token, two people with the exact same phone but using different networks and different iPhone VPN providers may have different speeds. The variables include:
The ISP You Are Using
The iPhone lists having an ISP as a requirement. The speed at which the ISP communicates with your iPhone VPN server is the most important. This transaction takes up about 20% of your speed considerations. International routing is not as fast as domestic (U.S.) routing. Many times special servers route traffic through countries and this slows your speed. One way to test these routing protocols is to visit the speed test page of a prospective iPhone VPN service provider. You can get a speed estimate according to ISP and country.
Your Wi-Fi or Cellular Network
Your speed on the iPhone VPN is dependent on the quality and speed of your Wi-Fi or Cellular Network. The iPhone initiates contact in the following manner.
- It connects to the last Wi-Fi that you used, either a hotspot, or your work or home Wi-Fi.
- If none are shown, you are presented with a list of wireless networks to choose from.
- If you choose not to join a Wi-Fi network or there are none, your iPhone continues to seek connection to an ISP over a cellular data network.
- If Wi-Fi or a cellular data network is not available, the iPhone cannot connect to the Internet or to an iPhone VPN.
Your speed on Wi-Fi or a Cellular Network will depend on the Wi-Fi configuration and the cellular network configuration. For example, the 802.11a/g Wi-Fi protocol is very fast, but the coming 802.11n will be faster and 4G cellular networks are faster than 3G. In addition, if the networks are clogged with other users, your speed will suffer.
Apple iPhone Operating System (iOS)
iPhone Central Processing Unit (CPU)
The A4 CPU in the iPhone 4 has much less horsepower than the dual-core A5 chip in iPhone 4S (advertised as up to two times faster).
Technical differences in iPhone VPN Protocols
L2TP is more secure than PPTP, but not as fast. PPTP is faster and its security issues are being addressed. iPhone VPN users should investigate these protocols authorized for the iPhone.
- L2TP/IPSec (Layer 2 Tunneling Protocol over the IP Security Protocol)
- PPTP (Point to Point Tunneling Protocol)
- Cisco IPSec
- Juniper Junos Pulse
- Cisco AnyConnect
By analyzing the variables that affect VPN speed, you can select the provider that best meets your needs.
